Understanding search engine algorithms

Essentially, an algorithm is a series of logical and mathematical steps used to solve a problem or accomplish a task.

As far as search engines are concerned, the algorithm's primary mission is to classify and organise all the web pages available in order to provide users with the most relevant results possible when they carry out a search.

General operation of a search engine algorithm

A search engine's algorithm generally follows three main stages:

    1. Crawl : Search engine robots are constantly exploring and retrieving information from the web.
    2. Indexation : The robots store and organise this information in a indexa gigantic database of all web pages.
    3. Ranking: When a user performs a search, the algorithm sorts the indexed pages according to their relevance to the query and presents them in the form of results.

Over the years, search engines have evolved considerably to offer a wide range of search options. increasingly sophisticated algorithmsThey are capable of identifying and classifying billions of web pages according to a multitude of criteria. To do this, they use hundreds of "signals" to assess the quality and relevance of a web page.

The main criteria taken into account by the algorithms

Although each search engine has its own algorithm and its own secrets regarding these criteria, it is possible to distinguish certain major aspects that influence the ranking of web pages in the search results.

Keywords are at the heart of the search process: they enable the algorithm to understand what web users are looking for.

Therelevant use of keywords in the content of a page (title, body text, tags) is a key factor in being well positioned in search results ( SEO ).

Search engines place a great deal of importance on the added value of a page, i.e. its ability to offer useful, complete and high-quality information to Internet users. A page with original, well-structured content is more likely to rank well in the results.

Site popularity and authority

Search engine algorithms also assign a certain authority to websites based on their notoriety, age and reliability. So a site that is recognised as an expert in its field will generally be better positioned in the results than a less well-known or less reputable site.

User experience

L'user experience is a criterion that is increasingly taken into account by search engines, as it reflects the overall quality of a website.

This includes elements such as loading speed pages, ergonomics and responsive design.

Changes and updates to search engine algorithms

In order to provide users with the best possible results, search engines regularly update their algorithms to improve their efficiency and combat fraudulent practices (spam, abusive referencing).

Major updates and impact on SEO

Some updates are considered major because they cause significant changes in the ranking of web pages in search results.

These updates generally concern one or more specific criteria of the algorithm and can have major consequences for websites, particularly in terms of SEO (Search Engine Optimization).
