Crawl analysis

What is SEO crawl analysis?

The SEO crawl analysis is a method used by the experts to examine and understand how search engines crawl, index and evaluate a website.

This analysis enables us to identify technical problems, errors and irrelevant pages that can have a negative impact on a site's SEO performance.

Tools to use for SEO crawl analysis

To carry out an SEO crawl analysis, there are several tools available on the market, some of which are free and some of which you have to pay for. Here are a few examples:

  • Google Search Console This free tool from Google provides invaluable information about crawling and indexing problems, as well as the errors encountered.
  • Screaming Frog SEO Spider This pay software (with a limited free version) allows you to crawl a website and retrieve various useful data for your SEO audit.
  • OnCrawl SEO log analysis: this paid platform offers an SEO log analysis service, ideal for gaining a better understanding of how Google crawls and indexes a site.

Steps for carrying out an SEO crawl analysis

To carry out a successful SEO crawl analysis, you need to follow a number of key steps:

1. Site crawl

This first step involves crawling your website using a tool like Screaming Frog SEO Spider or OnCrawl. The aim is to retrieve all the URLs (pages, images, CSSetc.) on your site to analyse its structure and SEO performance.

2. Analysis of errors encountered

Once the crawl is complete, it is important to examine the errors detected by the tool used. The most common errors include :

  • 404 errors These errors occur when the requested resource cannot be found on the server. 404 errors must be corrected quickly to avoid penalising theuser experience and natural referencing.
  • Temporary redirections (codes 302 or 307): temporary redirects can cause indexing problems because they tell search engines that the target page has only been temporarily moved. It is preferable to use permanent redirects (301) to ensure better indexation.
  • Exploration errors These errors are detected by Google Search Console and may be linked to server connectivity problems, blocked URLs or resources that are inaccessible to extraction robots.

3. SEO performance analysis

At this stage, you need to check a number of key elements in order to assess the effectiveness of your SEO strategies :

  • Meta-titles and meta-descriptions Make sure that these elements are optimised for each page, that they comply with best practice (size, relevant keywords, etc.) and that they are unique.
  • Hn tags h1, h2, h3 tags: check whether your site uses h1, h2, h3, etc. tags correctly, to structure the content and make it easier for search engines to understand.
  • Duplicate content Check whether there are pages with identical or very similar content that could lead to penalties in terms of natural referencing.
  • Canonical URLs tags: check whether your site uses rel="canonical" tags correctly to avoid problems of duplicate content.

4. Mapping and prioritising actions

Once the analysis is complete, it is crucial to prioritise the actions to be taken to improve the optimisation of your website. To do this, draw up a list of recommendations according to their impact on SEO performance:

  1. Priority actions These are actions that require little effort and have a significant impact on natural referencing (for example, correcting 404 errors and optimising meta-titles).
  2. Secondary shares They require more effort, but can also offer significant improvements in terms of visibility and traffic.
  3. Long-term equities They are carried out over time and do not offer immediate improvements, such as the production of content or improvements to the site's structure.

By following these key steps, you will be able to carry out an effective SEO crawl analysis tailored to the needs of your website. It is essential to repeat this analysis regularly to ensure that the optimisations you have made are bearing fruit and to quickly detect any problems encountered by the search engines when crawling your site.
