Programs and services for SEO website analysis

A website may look functional, load quickly in the browser, and contain high-quality content, yet still lose visitors from Google. This is often due to issues unnoticed by the owner: pages blocked from indexing, incorrect redirects, duplicate meta tags, weak interlinking, or poor search query matching.

SEO website analysis software helps detect such errors and collect data for correcting them. Some tools check the technical condition of pages, others display search queries, analyze competitors, or evaluate link profiles.

We'll explore free and paid SEO services, compare their capabilities, and show you how to conduct an initial website audit yourself. We'll also look at Seo-Gen's browser-based tools, which are suitable for specific SEO tasks.

What are SEO website analysis programs and why are they needed?

SEO analysis programs collect information about a website's health and help identify issues that may hinder search engine optimization. They check the technical parameters of pages, analyze content, examine search results, and show changes in website visibility for selected queries.

Some data is available directly to the website owner through Google Search Console and Google Analytics 4. Additional services are used for competitor research, bulk URL crawling, and backlink checking.

Automatic reporting helps identify problems faster, but their impact must be assessed separately. For example, identical titles for pagination pages and main commercial categories require different approaches to fixing them.

What tasks do SEO programs solve?

The capabilities of SEO tools depend on their purpose, available data sources, and data processing methods. For a comprehensive analysis, multiple programs are typically used, each responsible for a specific part of the analysis.

Most often, SEO programs are used for the following tasks:

• Technical audit of the site. Finding 404 errors, bad redirects, duplicate pages, and robots.txt, sitemap.xml, and canonical issues.
• Indexation analysis. Checking the availability of pages for search robots and finding out why they are not listed in Google.
• Keyword selection. Collecting the semantic core, studying search volume, search intent, and grouping queries.
• Competitor analysis. Comparison of search visibility, site structure, content, queries and link profiles.
• Rank tracking. Tracking changes in Google search results for selected queries and regions.
• Content analysis. Checking meta tags, H1–H6 headings, text structure, and keyword usage.
• Backlink check. Studying donor sites, anchors, new and lost links.
• Speed analysis. Assessing Core Web Vitals, mobile performance, and page loading issues.

The results of these checks help create a correction plan and determine the sequence of SEO work. For a small website, some tasks can be accomplished with free tools, but a large online store will typically require a more comprehensive suite of programs.

What's the difference between an SEO analysis program and an online service?

The main difference lies in the way they work with data and access features. Desktop programs are installed on a computer, while online services are launched through a browser and typically process information on their own servers.

Both formats are suitable for SEO audits, but they differ in limitations, automation capabilities, and ease of collaboration. When choosing, consider the number of pages being audited and the frequency of re-audits.

Programs installed on the computer

Desktop solutions include Screaming Frog SEO Spider and Netpeak Spider. They crawl a website using internal links, collect technical URL parameters, and generate reports on any issues found.

These programs are convenient for bulk crawling of thousands of pages, analyzing redirects, and comparing scan results. The amount of processing available depends on the license, program settings, and computer resources. When working with large sites, it's necessary to monitor the server load.

Online services and browser extensions

The online SEO analysis service runs without installing any separate software. The user enters the website address, connects the project, or uploads data, and then receives the results in the service interface.

Browser extensions, such as SEO META in 1 CLICK or META SEO Inspector, are suitable for quick tasks. They help you view meta tags and some technical elements of the open page. However, an extension is no substitute for a full site scan or search statistics analysis.

What types of SEO tools are there?

It's easier to choose SEO programs based on the tasks you need to solve on a specific website. Technical accessibility checks, semantic analysis, and competitor research require different data, so the services' functions vary significantly.

Before purchasing a subscription, it's helpful to determine what information is already available in free tools. This is especially important for small website owners who don't require the constant use of expensive analytics platforms.

Technical audit tools

Technical audit programs check page accessibility, HTTP response codes, internal links, and indexing parameters. They help identify errors in the website structure that are difficult to detect during a normal page review.

For example, crawling may reveal that some products link to deleted categories, and several important landing pages redirect users through a redirect chain. The resulting URLs can be exported to a spreadsheet and passed on to the developer along with the required corrections.

Semantic and competitor analysis services

These platforms collect search queries, evaluate their popularity, and help identify competitors' pages receiving organic traffic. They also show keyword overlaps and thematic areas that are not yet fully covered on the website being analyzed.

Competitor data is often estimated, as analytics services don't have access to their internal statistics. Therefore, the results are useful for comparison and identifying opportunities, but are not suitable for accurately determining other companies' traffic.

Programs for link analysis

Link services collect information about pages that link to the domain being researched. They are used to study the number of donors, link types, anchor text used, and changes in the link profile.

The donor's topic, region, page language, and link context require special attention. A large number of backlinks alone does not guarantee good website visibility. When analyzing, it's important to evaluate the quality of the sources and the naturalness of the link profile.

Tools for content analysis and search performance

Content tools help check the title, description, heading structure, and keyword usage. Some programs compare page content with competitors' materials and highlight topics that might be useful to readers.

Search performance is assessed based on impressions, clicks, CTR, and ranking dynamics. Google Search Console is used for this analysis, while visitor behavior and conversions are analyzed using GA4. This combined analysis helps identify pages that require additional optimization.

Comparison of the best programs and services for website SEO analysis

The market offers everything from small tools for a single check to platforms with dozens of SEO reports. The differences between them lie in the depth of analysis, the amount of available data, automation, and cost.

Below is a comparison of popular solutions based on their primary purpose. Free access may come with limitations on the number of queries, pages crawled, or report depth.

The subscription price doesn't always reflect the usefulness of a particular service for a project. If you only need to check a single page after changing meta tags, launching a complex analytics platform is usually overkill.

For a large online store, the situation is different: regular crawling, saving error history, and exporting reports significantly reduce the time spent on technical checks. Therefore, programs should be compared based on the required functions, not the number of features listed in the advertising description.

Free SEO analysis software and services

Free SEO tools are suitable for initial website diagnostics, indexing monitoring, and search engine performance analysis. Many of them provide data directly from Google, which cannot be obtained with the same accuracy through third-party platforms.

A good place to start is with Google Search Console, Google Analytics 4, and PageSpeed Insights. These services cover several important areas of analysis and help you understand which additional programs are truly necessary.

Google Search Console – indexing and search performance analysis

Google Search Console shows how website pages are presented in Google search. The owner of a verified resource can study search queries, clicks, impressions, CTR, average position, and index status.

The URL inspection tool is particularly useful. It displays information known to Google about the page, the selected canonical URL, and any detected restrictions. After fixing the issue, you can request a re-inspection, although this doesn't guarantee the page will immediately appear in search results.

For regular SEO analysis, it's worth comparing metrics across individual pages, countries, devices, and time periods. For example, a decrease in CTR with stable impressions may prompt a check of the title, snippet, and changes in search results.

Google Analytics 4 – organic traffic analysis

Google Analytics 4 helps you study visitors coming from organic search and their actions on your site. Reports let you analyze sessions, acquisition sources, events, key events, and results for individual landing pages.

For an online store, it's useful to track product views, cart additions, and purchases. On a service website, you can measure form submissions, contact page clicks, and other significant actions if they are properly configured in the analytics system.

GA4 shows visitor behavior after landing on a website, but it doesn't provide a full list of Google search queries. To analyze queries, it's used in conjunction with Search Console, after setting up links between the resources.

Google PageSpeed Insights – website speed check

PageSpeed Insights analyzes page performance separately for mobile and desktop devices. The report includes Lighthouse diagnostic data and, where sufficient data is available, real-user metrics from the Chrome UX Report.

The service helps detect issues with images, JavaScript, CSS, loading of important elements, and interface stability. After technical fixes, the page should be re-checked, comparing the results under identical conditions.

Lab scores may vary between runs due to testing conditions. Therefore, a single Lighthouse score should not be taken as definitive proof of a site's speed.

What Core Web Vitals metrics should I check?

Core Web Vitals describe three user experience characteristics: speed of primary content appearance, interface responsiveness, and page visual stability. Google uses a separate metric for each characteristic.

Key metrics:

• LCP (Largest Contentful Paint). The time it takes for the largest visible content element to appear. A value of no more than 2.5 seconds is considered good.
• INP (Interaction to Next Paint). Interface response time to user interactions. A good result is no more than 200 milliseconds.
• CLS (Cumulative Layout Shift). The total value of unexpected element displacements. A value of no higher than 0.1 is considered good.

These metrics are assessed based on real user data, when available, and in accordance with Google's established methodology. Fixing Core Web Vitals is beneficial for user experience, but does not by itself guarantee ranking gains.

Google Trends – analysis of interest in search queries

Google Trends shows the change in the relative popularity of search queries over a selected period. You can compare topics, regions, seasonality, and audience interest in specific business areas.

For example, for an online store selling climate control equipment, the service can help identify seasonal fluctuations in demand. For a medical website, it can compare interest in specific informational topics and determine the appropriate time to prepare content.

Google Trends uses a normalized metric between 0 and 100. Therefore, its data cannot be interpreted as an exact monthly search volume. Estimating absolute search volume requires additional sources.

Software for technical SEO website audit

A technical website audit is especially useful after migrating to a different CMS, changing the URL structure, or performing a mass catalog update. In such situations, errors can affect hundreds of pages simultaneously, and manual verification would be too time-consuming.

Specialized programs crawl internal links and collect information about the URLs they find. The resulting reports help identify systemic issues and verify whether developers have actually fixed the detected bugs.

Screaming Frog SEO Spider

Screaming Frog SEO Spider is installed on your computer and scans your website like a search engine crawler. The program collects HTTP statuses, headers, meta tags, canonical tags, internal links, and other technical information.

It's easy to find broken links, duplicate titles, pages without descriptions, and long redirect chains. Results can be filtered, compared, and exported for further work.

Screaming Frog has a free version with a limited number of crawled URLs and a paid license with advanced features. For a large site, it's important to properly configure crawl depth, request speed, and JavaScript processing.

Netpeak Spider

Netpeak Spider is designed for mass technical analysis of websites. The program helps check indexing directives, links, redirects, meta tags, and other parameters of individual pages.

The ability to collect errors by URL groups is especially useful for online stores. For example, you can analyze categories, product pages, and information sections separately and then compare the number of issues.

Netpeak Spider reports are suitable for delegating tasks to technical specialists. However, automatic alerts should be checked in the context of the site, as some detected features may be intended by its architecture.

Sitechecker

Sitechecker provides tools for website auditing and tracking technical changes. The service is suitable for those who prefer a browser interface and want to keep a history of detected issues.

Depending on the features and plan selected, page audits, site monitoring, and additional SEO reports are available. This is convenient for regular project work, when you need to check the results after each set of edits.

Before connecting a project, it's worth checking the page count and crawling frequency limitations. The terms of use may vary significantly for a small business-card site and a large catalog.

What technical errors should SEO programs find?

A good SEO analysis program should display not only individual warnings but also the URLs where the issue was detected. Ideally, the user receives the page status, error type, and the data needed to reproduce it.

However, identical warnings on different websites may have different significance. For example, a missing description on a utility page and an erroneous noindex on the main commercial section require completely different priorities.

Indexing and HTTP status errors

The first step is to check pages that should appear in Google but are unavailable for indexing. This could be due to an erroneous noindex, a crawl restriction in robots.txt, server errors, or incorrect canonicalization.

HTTP codes help determine the technical status of URLs. A 200 response indicates successful processing of the request, 301 indicates a permanent redirect, 404 indicates a missing resource, and 5xx errors are related to server issues.

Long redirect chains and internal links to old addresses should be checked separately. Even if the redirect works, it's usually better to point the internal link directly to the final, current URL.

Duplicate pages, canonical, and sitemap.xml

Duplicates occur due to URL parameters, versions with and without a slash, catalog filters, or multiple URLs with identical content. An SEO crawler helps collect such pages and compare their technical parameters.

Canonical specifies the preferred address, but search engines may choose a different URL if they receive conflicting signals. Therefore, it's important to check redirects, internal links, page accessibility, and the contents of your sitemap.xml.

An XML sitemap helps Google find the right URLs, but it doesn't guarantee their indexing. It typically includes relevant canonical pages that are actually intended for search results.

Mobile version, speed and internal links

Technical analysis examines the ease of use of a website on a smartphone. It's important to evaluate the readability of the text, the functionality of the menu, the accessibility of buttons, the stability of the interface, and the loading of the main content.

Internal links help search engines find pages and understand their place in the site's structure. If an important category is only accessible through internal search or JavaScript, it's important to check whether Google can detect links to it.

Websites with multiple language versions are additionally checked for hreflang accuracy. Errors in language URLs and cross-references can make it difficult to display the correct version of a page to users in different regions.

Paid SEO services for competitor analysis and promotion

Paid platforms are especially useful for researching competitors' search queries, tracking rankings, and planning site structure expansion. They collect large amounts of information and provide domain comparison tools.

When choosing such a solution, it's important to consider the availability of data for Ukraine and the required languages. A large international database alone does not guarantee high-quality analytics for a narrow local niche.

Ahrefs – competitor, keyword, and backlink analysis

Ahrefs is used to study organic visibility, semantics, and link profiles. Using Site Explorer, you can explore a competitor's domain, find prominent pages, and view the queries for which the service detects its rankings.

Keywords Explorer helps you explore keywords and related search queries. Link analysis includes information on donors, anchor text, and changes to the detected profile.

Ahrefs is useful for identifying topic gaps and planning link building. However, the estimated traffic figures and the platform's own metrics should be viewed as analytical estimates, not Google statistics.

Serpstat – semantics, SEO audit and monitoring

Serpstat combines tools for keyword research, competitor analysis, technical audits, and search ranking checks. The service is suitable for regular work on multiple websites and SEO reporting.

When analyzing competitors, you can look for overlapping queries and pages that rank for important thematic groups. This information helps you identify missing sections of your website and refine the content of existing pages.

For a Ukrainian project, it's essential to validate the selected search engine database, region, and language. This will determine how closely the queries received match the actual demand of the target audience.

SE Ranking – comprehensive search engine optimization analytics

SE Ranking is used for ranking monitoring, competitor research, and technical SEO audits. The platform also provides semantic and link profile analysis tools.

The service is convenient for projects that require regular monitoring of rankings in different regions and comparing changes after content publication. When setting up monitoring, you must correctly select the country, device, and search engine.

Agencies benefit from reporting and the ability to manage multiple projects in a single interface. Before purchasing, compare plan limits for the number of queries, sites, and available audits.

Similarweb – Competitor traffic assessment

Similarweb is used to compare website audiences and visitor acquisition channels. The service helps explore the estimated traffic structure, audience geography, and certain characteristics of competing resources.

For example, you can see what share of estimated visits comes from organic search, direct visits, or other channels. This information is useful when studying a competitor's overall marketing strategy.

For small websites, the accuracy of estimates may be limited due to a lack of available data. Therefore, Similarweb is best used for comparative analysis rather than substituting its calculations for your own Google Analytics metrics.

How to choose a competitor analysis service for the Ukrainian market?

To promote in Ukraine, it's necessary to check Google support, Ukrainian and Russian languages, regional databases, and local search queries. The difference is especially noticeable when analyzing services tied to a specific city.

For example, a service might be good at finding high-frequency queries by country but miss smaller local groups. Therefore, it's advisable to validate the semantic core using multiple methods and compare it with actual search results.

An international project will require additional assessment of language versions and geography. Russian services primarily focused on Yandex should not be used as the primary source of Ukrainian Google SEO analytics.

Tools for analyzing keywords, texts, and links

After technical diagnostics, it's necessary to check how well the website's structure and content meet the needs of potential visitors. This is done using semantic, content, and backlink analysis programs.

These areas are interconnected but address different objectives. Semantics helps understand demand, text analysis reveals the quality of topic coverage, and link services allow you to explore external mentions and donors.

Programs for selecting and clustering keywords

Keyword selection begins with identifying the website's primary products, services, and content areas. The queries are then expanded using Google Keyword Planner, Ahrefs, Serpstat, SE Ranking, and other available sources.

After collecting semantics, it's necessary to remove irrelevant variants, check search volume, and determine search intent. Queries with similar wording aren't always suitable for the same page, so their distribution requires search results analysis.

Semantic clustering helps organize queries into thematic groups and prepare the structure of landing pages. For preliminary work, you can use Keyword Generator Seo-Gen and the clustering tool.

SEO text and meta tag analysis services

SEO text analysis helps identify repeated keywords, overly long fragments, and insufficiently covered topics. This is accomplished using text analyzers, heading checking tools, and page comparison services.

Particular attention is paid to ensuring that the Title, Description, and H1 tags are consistent with the page's content. The title should explain the topic to the user, and the meta tags should accurately describe what the visitor will find after clicking on the link.

When working with content, they also evaluate the H2-H4 structure, internal links, the usefulness of tables, and the completeness of answers. High-quality SEO copywriting requires an understanding of the topic, not a mechanical distribution of queries across paragraphs.

Why doesn't high keyword density guarantee rankings?

Keyword density measures the frequency of a particular word or phrase relative to the text's volume. This metric is useful for editorial review, especially when an author repeats the same constructions too often.

However, search relevance depends on the page's content, the quality of the response, the site's structure, and other factors. There is no universal density percentage that guarantees good Google rankings.

For analysis, it's helpful to check for repetitions and then read the text as usual. If keywords interfere with comprehension, they should be replaced with natural wording or removed without losing meaning.

Link profile analysis tools

Backlink analysis helps us understand which sites link to a domain and how its link profile is changing. This research uses Ahrefs, Serpstat, other link platforms, and available Google Search Console data.

The reports focus on the donor's subject matter, anchor text, regional affiliation, and link type. The nofollow, sponsored, and ugc attributes are checked separately, if available.

When evaluating links, don't rely solely on DR, number of domains, or other numerical metrics. The content of the source page, organic visibility, natural placement, and relevance to the topic of the website being promoted are all important.

Seo-Gen online tools for self-checking your website

One-time SEO checks don't always require installing software or paying for a subscription to a large analytics platform. Often, it's enough to check a specific URL, identify the error, and forward the results to the specialist responsible for the site.

The Seo-Gen tools section contains 49 tools for working with technical parameters, texts, semantics, links, and search results. They are launched via a browser, and the availability of individual checks depends on the tool selected.

SEO analysis of a page without installing software

SEO Checker Seo-Gen is suitable for initial review of a single page. This format is convenient before publishing new material, after changing meta tags, or when troubleshooting a technical error.

The user enters the page address and reviews the available analysis results. After checking, they can proceed to individual tools for a more detailed analysis of the detected issues.

If you need to check the response code of a specific URL, use HTTP Status Checker. To detect incorrect redirects, you can use Redirect Checker.

For widespread issues, it's advisable to supplement the results of a targeted check with a full site crawl. This helps determine whether the error affects a single page or is repeated across the entire section.

Speed and Core Web Vitals check

PageSpeed Checker Seo-Gen is designed to test speed and Core Web Vitals metrics. It allows you to examine individual pages and identify potential performance issues.

It's recommended to test different types of pages: homepage, category pages, product pages, and primary commercial landing pages. Their speed may vary due to images, additional scripts, and template features.

After optimizing images or changing CSS or JavaScript, you should repeat the test. It's best to compare the results with available field data, as lab results may fluctuate between runs.

Keyword and SEO text analysis

Keyword Density Checker helps analyze the frequency of words and search phrases. This tool is useful for preparing SEO articles, editing commercial pages, and detecting excessive repetition.

Separate tools for selecting, checking search volume, and clustering queries are available for preparing the semantic core. These tools allow you to pre-form keyword groups before analyzing search results.

When analyzing meta tags, a snippet preview is also useful. It helps you estimate what the Title and Description might look like, although the final presentation of the result in Google is determined by the search engine itself.

Checking website backlinks

Backlink Checker Seo-Gen is designed to check backlinks and explore available link profile information. It can be used as a starting point before conducting a more detailed donor analysis.

When conducting a link audit, it's important to consider more than just the number of links found. You also need to check the link's origin, whether the page matches the site's theme, and how natural the anchor text appears.

For internal problems, Broken Link Checker will be useful. It helps identify broken links that may prevent users from moving between sections and make it harder to crawl the site.

What to do after errors are detected?

An automated check typically concludes with a list of comments and technical indicators. Next, it's necessary to determine which issues affect important pages and which can be addressed through scheduled maintenance.

Priority depends on the scale of the error, its frequency, and the role of the affected URLs. For example, an incorrect canonical on the main page of a commercial section requires more careful review than a minor flaw in a secondary image.

Errors you can fix yourself

A website owner with access to the CMS can independently change meta tags, fix an obvious internal link, or update outdated text. Such actions typically don't require changes to the overall site architecture.

Before saving, it's a good idea to check that the same settings aren't being used on multiple pages. For example, editing the general Title template could affect the entire catalog, even if the user intended to change just one category.

After making the correction, open the page, check the result, and ensure that the changes have been reflected in the source HTML. If the site uses caching, you may need to wait for the cache to update or clear it using the established method.

Errors that should be handed over to an SEO specialist or developer

System issues include mass URL duplicates, incorrect redirects, incorrect section indexing, and multilingual errors. These fixes often involve server settings, routing, and CMS templates.

Incorrectly changing robots.txt or canonical can result in important pages being excluded from search results. Therefore, before implementation, it's important to prepare a list of affected URLs, the expected behavior, and the verification process.

If the automatic report contains many comments, it's useful to conduct a technical SEO audit. It helps identify the causes of errors and prepare tasks for the developer, taking into account the site structure.

How to conduct a website SEO analysis yourself: a step-by-step guide

It's easier to conduct an independent audit sequentially to avoid wasting time on minor issues. First, ensure that the main pages are accessible to search engines, then check the technical parameters and content of the site.

Let's look at a process for a small service website that receives some traffic from Google. This algorithm is suitable for initial diagnostics and helps determine whether a more detailed audit is required.

Step 1. Check your website's accessibility for search robots

Start with the homepage and a few important landing URLs. Check HTTP statuses, robots.txt accessibility, the presence of a sitemap.xml, and the absence of erroneous indexing restrictions.

Then, examine the canonical and ensure it points to the correct version of the page. If there are multiple languages, additionally check the hreflang and the accessibility of the associated language URLs.

In Google Search Console, open the URL Inspection tool and check the page status known to Google. If it's indexable but not visible in search results, examine the internal links, content quality, and URL discovery information.

Step 2. Find errors on pages

After checking indexation, move on to the Title, Description, H1, internal links, and the technical condition of the pages. For a small site, you can start with individual online checks, and for a large number of URLs, use a crawler.

Pay attention to duplicate meta tags, broken links, redirects, and content on important landing pages. If errors are found on multiple similar URLs, check the corresponding CMS template.

Analyze your site's loading speed on mobile devices separately. Issues with images, unstable elements, and heavy scripting can degrade the user experience and prevent visitors from completing their desired actions.

Step 3. Check semantics and competitors

Create a list of key services and queries that users might use to search for your website. Then compare it to existing landing pages and identify unmet audience needs.

To analyze competitors, examine Google search results for selected queries. Pay attention to the content, heading structure, terms and conditions, tables, FAQs, and internal links.

Don't copy your competitor's structure entirely, as their website may address different needs. Use the patterns you've discovered to refine your own structure and prepare any missing content.

Step 4. Check links and search performance

Open the Google Search Console performance report and compare clicks, impressions, CTR, and average positions for the relevant periods. If necessary, break down the data by page, country, and device.

In GA4, check organic traffic and visitors' target actions. If traffic to specific pages is declining, compare search metrics with changes to your site structure, content, and competitive search results.

After this, examine your link profile and internal linking. Pay particular attention to important pages without sufficient internal links and URLs reached via outdated redirects.

Step 5. Create a list of fixes by priority

It's best to present the analysis results in a table, listing the affected URLs, the probable cause, and the required action for each error. This document is convenient for delegating tasks to a developer or content specialist.

Example of prioritization:

Priorities shouldn't be determined solely by the type of alert. The page's traffic, its commercial importance, the scale of the issue, and the risk of changes must be considered.

The general sequence of the check is as follows:

HTTP statuses → indexability → technical errors → structure and content → semantics → links → search performance → fix plan.

After implementing the changes, a rescan is performed and the results are compared with the original report. This helps verify that the issue has been resolved and that no new errors have appeared.

How to choose a program for SEO website analysis?

The choice of software depends on the site's size, the user's skill level, and the tasks that need to be performed regularly. A simple online tool is sufficient for checking the meta tags of a single page, but working with a large catalog requires more advanced features.

Before purchasing a subscription, it's a good idea to run a few trial checks and evaluate the reports you receive. It's important to understand what data the service provides, how accurate it is, and whether it can be used for a specific project.

For a beginner specialist and a small website owner

At the initial stage, Google Search Console, GA4, PageSpeed Insights, and separate SEO tools for page auditing are sufficient. This set helps analyze organic traffic, indexing, and key technical parameters.

It's worth adding additional programs as tasks arise that can't be solved with free tools. For example, to check a few dozen pages, you can use the available crawler features, or try a specialized service for competitor research.

There's no need to buy several similar platforms at once. It's more helpful to first learn how to read reports, correctly identify the causes of errors, and test the results after making changes.

For an online store or a large website

Online stores often contain thousands of product pages, filters, categories, and pagination pages. Manually checking such a structure is inconvenient, especially if the catalog is constantly updated.

Screaming Frog, Netpeak Spider, and other mass crawling solutions are suitable for technical audits. Additionally, monitoring indexing, server response status, and internal link structure is required.

When choosing a program, consider the volume of URLs processed, JavaScript support, CSV export, and the ability to automate re-checks. For larger projects, it's also useful to work with server logs and analyze site crawls by search engines.

For an SEO agency

An agency typically requires several types of tools: a technical crawler, a semantic analysis service, position monitoring, and a competitor research platform. Separate solutions are used for link auditing and reporting.

The appropriate set depends on the number of projects, the regions being promoted, and the available budget. If the agency works with Ukrainian and international websites, it's important to consider support for the relevant search engine databases.

Lead SEO specialist — Gennady

I use several SEO analysis programs because a single service doesn't provide a complete picture of a site's health. Google Search Console helps you see queries and pages that are already receiving impressions, Screaming Frog helps you find technical errors, and Ahrefs or Serpstat helps you study competitors and missing keywords.

An automatic report can contain hundreds of issues, only a fraction of which require immediate correction. Therefore, I start with technical accessibility and indexing, then check the page structure, search queries, and links. This order helps me understand the root cause of problems and avoid wasting time on fixes that will make virtually no difference.

What should you pay attention to before paying for a subscription?

Before purchasing a program, it's a good idea to create a list of specific tasks and compare the capabilities of several services. It's especially important to check the limits on the number of projects, queries, crawled pages, and available reports.

Main selection criteria:

• Geography and languages. The service must support the required search regions and provide sufficient data on the target audience.
• Depth of verification. It is necessary to find out which technical parameters are being analyzed and how detailed the error reports are.
• Usage limits. The number of URLs, projects, keywords and available queries to the system should be taken into account.
• Data export. The availability of CSV, tables, reports and integrations with other analytical tools is desirable.
• Automation. APIs, scan schedules, and change notifications are useful for regular checks.
• Cost for the team. When calculating your budget, you need to take into account the number of users, additional modules, and limitations of the selected plan.

It's best to make a final decision after testing the service on a real task. If the service's reports are clear, the data is suitable for your region, and the limitations don't interfere with your work, a subscription may be worth it.

What mistakes are made when using SEO programs?

One common mistake is to evaluate a website's quality solely based on its automatic SEO Score. Such metrics are calculated according to the specific service's rules and are not a direct assessment by Google.

There's also a common confusion between the technical feasibility of indexing and a page's actual presence in search results. Even if a URL returns a 200 and doesn't contain a “noindex” tag, Google may not add it to the index for other reasons.

Another problem is related to competitor assessment. Third-party services calculate organic traffic based on their own databases and models, so their figures may differ from actual traffic.

Content automation deserves special attention. Artificial intelligence programs and services can speed up data collection, query grouping, and drafting, but the results require factual verification.

Don't fix every warning you find without assessing the impact. Incorrectly changing robots.txt, canonical, redirects, or internal links can cause more harm to your site than the original issue.

To work safely, a simple procedure is needed: detect the error, check its cause, identify the affected pages, prepare a fix, and recheck the result.

A high-quality SEO analysis usually requires a combination of several programs. Google Search Console and GA4 help study search performance, crawlers detect technical errors, and analytics platforms provide data on competitors, semantics, and links.

Start with the checks that your site really needs. In the Seo-Gen tools catalog, you can choose the appropriate service, check the page and determine further actions.

If you find widespread indexing errors, structure problems, or unclear technical warnings, order an SEO website audit. Seo-Gen specialists will help you understand the causes and prepare a specific plan for correction.
