What is a meta description?

The meta description is an HTML tag that provides a concise summary of the content of a web page. It usually appears below the page title in search engine results.

It is designed to inform the user about the main topic of the page before they click on the link.

This description is not part of the content visible directly on the page, but it is included in the source code to assist search engines.

Why use meta descriptions and what is their purpose?

Using a meta description improves a website's natural search engine optimization by making its pages more attractive in search results. A clear and relevant description encourages users to click on a link.

It also helps distinguish your page from other results by providing a quick and accurate preview of the content, which can increase the click-through rate (CTR).

Furthermore, even though Google does not always consider meta descriptions to be a direct ranking factor, they remain an essential element for user experience and website visibility.

How does the Meta Description work in practice?

La méta description est incluse dans la section <head> du code HTML d’une page web à l’aide de la balise <meta> avec l’attribut "name="description"".

Search engines retrieve this description to display it under the title when presenting results. If no meta description is defined, the engine uses excerpts from the page content to generate a summary.

Its recommended length is generally between 150 and 160 characters so that it is fully visible in the results without being truncated.

What are the advantages and disadvantages of meta descriptions?

The benefits of meta descriptions include better presentation of pages in search results, which can increase click-through rates and improve visibility.

It also provides an additional communication opportunity to quickly explain the relevance of the content to the user.

However, its limitations lie in the fact that Google does not always guarantee that it will use the description provided, and may choose a different excerpt if it deems it more relevant.

Furthermore, poor writing or over-optimization can damage the site's image and appeal.
