When considering website audits from the perspective of SEO auditing tools users, paying particular attention to platform capabilities, ease of use, data accuracy, integrations, etc., is essential. In this study, we will consider all the factors that affect the analysis of website efficiency and help you understand them in more detail. We will also discuss website usability and the brief/specification for developers based on the tech SEO audit results to provide you with a quick error correction algorithm.

How to Do an SEO Audit?

A regular, independent technical audit is a crucial step in maintaining the effectiveness and optimization of a site. It's worth noting that the recommended frequency of such an SEO site analysis depends on the page amount, changes in content or search engine algorithms, or even the frequency of reviewing your promotion goals. However, general recommendations suggest conducting an audit at least once a quarter. This allows you to identify potential SEO issues and make timely adjustments.

An audit is necessary when changes such as content updates, site structure modifications, and adding new features occur. It's also essential to check the quality of SEO services a contractor (agency) or an in-house team provides.

Furthermore, sometimes, it's essential to analyze competitors' websites' performance to identify improvement opportunities and evaluate the optimization level. You can use specialized services like Serpstat, Screaming Frog, and Netpeak Spider for competitor analysis. For elemental analysis of your site, the basic features of Google Search Console are sufficient.

The main steps for conducting an autonomous audit include:

1.Analysis of technical parameters:
  • HTTP response status codes: 200, 301, 404, etc.
  • Meta tags and headings: Title, Description, H1-H6;
  • SSL certificate: validating the digital security certificate's presence and accuracy;
  • Microdata: the presence of certain types of microdata and its correctness;
  • Rel HTML attributes for backlinks, canonical tags, and redirects;
  • Robots.txt and Sitemap.xml files.
2.Typical site structure and navigation mistakes:
  • Indexing issues;
  • Categories, filters, catalogs, and their nesting;
  • Mobile responsiveness.
3.Content analysis:
  • Uniqueness, duplicated content;
  • Keyword optimization;
  • Content relevance.
4.Internal and external linking:
  • Checking for the broken links;
  • Interlinking optimization.

SEO analyzer tools can quickly check most of these parameters. Additionally, they can provide recommendations for correcting found errors. 

By the way, our specialists researched technical errors that most often occur in audit results:

Among them, problems with microdata, meta tags, and links stand out. We will briefly discuss how to correct them and create technical specs for devs directly in the exported Serpstat audit report.

How to Make an SEO Audit Report?

A technical audit of a website is just the first step towards its improvement. It's crucial for you to interpret data accurately and correct errors. There are several steps to preparing a technical specification for developers to fix issues:

1.Export the ready report of the site scanning results in a table format and supplement it by carefully studying Serpstat's recommendations.
2.Review the list of detected errors and their priority to adapt them to your requirements.
3.Add links to the necessary documentation or examples to set up site components correctly.
4.Specify the information other specialists must provide to correct errors (if necessary).

1.Complex interfaces can hinder understanding and use of all features.
  • Unrevealed metrics/data are challenging to comprehend.
  • Lack of explanations and recommendations for error correction.
  • Inconvenient platform navigation.
2.Free versions often limit the number of checks, depth of analysis, or access to certain features.
  • Just a few checks are available.
  • There are no key features in the trial or lack of a freemium plan or test period.
  • Restrictions on data export.
3.Data accuracy, as different platforms may provide varying results when scanning.
  • Inaccurate scan results or outdated information.
  • Incomplete range of analyzed metrics.
  • Errors in problem identification (may occur due to incorrect rendering of JS).

    Search Console reports provide statistics on site visits from organic search, various links, bounce rate, conversions, and technical information.

    Scan reports can yield essential information about the site's indexing status, including:

    • Errors must be corrected to improve the site's accessibility for search bots.
    • Indexed pages.
    • Advice on the site structure and its content for better indexing.
    • Pages excluded from the index and the reasons for their exclusion.

    The website structure defines the organization of content and navigation for users. When forming the structure, consider the following requirements:

    1.Minimum levels. Users should quickly find the menu, click on categories, and return to the menu if necessary. Structures should be built with at most three levels. Specialized platforms can check the number of clicks from the main page:
    2.Logic and brevity. Plan the structure so visitors can quickly find the information they want.
    3.Analysis of audience needs. Before developing the structure, it's essential to study not only keyword list but also the needs of your target audience.

    By following these guidelines, you can develop a well-structured website and enhance its usability. Moreover, a properly designed internal structure will improve search engines' indexing of pages.

    • Define your needs: site aspects, budget, the level of SEO experience required;
    • Compare different platforms: features, reviews, prices, and pricing plans;
    • Test the platforms: assess the interface for ease of use, simplicity, data accuracy, and available tools.

    The duration of an SEO audit can vary depending on the size and complexity of the website. A manual SEO audit for a small website with less than ten pages on average might take a few days. A broader audit for a more extensive site could take about one week to complete. For huge websites, the audit could extend to several weeks. Automated tools can speed up the process to one day, but manually reviewing the results by an SEO auditor is essential to ensure accuracy.
