The term SEO crawling refers to the process whereby search engine robots (also known as spiders or crawlers) explore and analyse a website to extract relevant data and information.

This involves browsing the content of your web pages to examine their performancestheir quality, structure and hierarchy, as well as to identify any potential structural defects.

Using a specific algorithm, these robots follow the internal and external links on a site, moving from page to page to analyse the content.

Once this information has been collected, it is sent to the search engine servers where it is sorted, indexed and used to determine the site's position in the search results.

How does the SEO crawling process work?

Le crawl is a complex process involving several stages. Here are the main ones:

1. Preliminary site analysis : Before starting to browse the content of a site, search engine robots examine its meta tags robots and its "robots.txt" file to check whether the owner has authorised or prohibited access to the site (or certain parts of it).
   
   
2. Links : Once this preliminary analysis has been carried out, the robots move from one web page to another by following the internal and external links present on the site. In this way, they exploit the site's hierarchical structure to discover and analyse all of its content.
   
   
3. Data recovery : When crawling the pages of a site, robots collect information such as the title, description, text, images, page layout, etc. This data is then transmitted to search engine servers where it is indexed. This data is then transmitted to search engine servers where it is indexed.
   
   
4. Content analysis and evaluation : Search engines use sophisticated algorithms to assess the quality and relevance of the information gathered during crawling. This process determines the position of a web page in the search results based on its quality and popularity.

Criteria taken into account by robots when crawling

During the SEO crawling process, robots take several factors into account to assess the quality of a site and determine its ranking in the search results. Here are some of the most important criteria:

• The quality of the content : The more relevant, rich, fresh and original your content, the more it will be appreciated by search engine spiders.
• Site architecture : A good navigation structure and a clear hierarchy help robots to better understand the organisation of your web pages and encourage indexing.
• La loading speed : Sites that load quickly and offer a high level of user experience are favoured by search engines.
• The number of links : Sites with a large number of quality inbound and outbound links generally rank higher in search results.
• Keywords: Relevant terms integrated into titles, subtitles, image alt tags and body text can improve your SEO performance.
