How do search engines work ?

SEO mainly focuses on Google. More than 90% of connected French people use Google at least once a day. Integrating this search engine into its problem and its SEO strategy is essential.

Google analyzes, indexes and ranks billions of pages daily. Robots explore the web and probe online sites, we speak of "crawl". If a page meets Google's technical expectations, then it will be indexed. Its position will depend on the relevance of its content on a given theme. From there, when an Internet user makes a request, he will obtain in response the pages that best define his request.

To do this, Google takes into account hundreds of criteria by which it judges the effectiveness and value of a page. SEO takes all these constraints into account and tends to respond to them to allow a site to position itself well.

In its quest for relevance, Google's algorithm is constantly evolving. Updates, each relating to precise criteria, mean that this search engine improves its capacity to deliver answers adapted to the requests formulated by the Internet users.

Google Panda: This update judges the quality of the content of a page or site.

Google Penguin: This is the net linking that is subject to analysis. The quality and relevance of this net linking can favor or penalize a site.

Google Colibri and RankBrain: Both are about understanding user intent. Thanks to this, the results submitted to the Internet user are always more targeted and best meet their request.

Google mobile-friendly: It’s mobile adaptability that is taken into account. "Responsive" sites are favored in terms of mobile indexing.

When the indexing and referencing criteria are not met, Google then applies penalties. The referencing of the site is then destroyed and the latter is found banished from the results pages. Algorithms are not the only ones to judge the quality of creation, manual sanctions can also intervene.

SEO audit and technical optimization recommendations

The SEO audit is the way to take stock and judge the effectiveness of a site. This audit will determine the most promising strategy for a project. The latter must take into account the expected technical specificities, as well as the particularities relating to the target market.
