A Meta Description is an HTML tag intended for search engines that describes the content of a web page. The content of this tag does not appear on the site but in SERP under the title of the page.
If the Meta Description is not filled in, search engines will generate one from the content of the landing page. Thus, the customization of Meta Description Tags, allows a better control of the snippets of the pages and the overall communication of the website.
How to optimize a Meta Description Tag?
The Meta Description does not directly influence the positioning of the page in SERP of search engines. On the other hand, by inciting Internet users to click, it represents a powerful lever of traffic towards the sites.
Like the Title Tag, the optimization of a Meta Description consists in finding the balance between the immediate understanding of the content of the web page by Internet users and the placement of keywords for search engines.
