Do you want to improve your site, make sure that all your pages are taken into account by Google? Or even check the structure of your site? Use Google Webmaster Tools.

Google Webmaster Tools, GWT for those in the know, is a free, relatively simple tool that lets you see how Google crawls your site. Soon the indexing of the search engine will have no more secrets for you ... and your site either! Forward, and beware of (bad) surprises.

Once you have set up your account, open the hood of your site! Among other things, you can:

Know how Google indexes (or not!) The pages of your site. GWT tells you the number of URLs submitted to Google, which ones are indexed and which ones go wrong. For these, it is up to you or your webmaster to repair them.
Know your traffic in more detail: what are your keywords that attract the most visitors? What are your internal links that refer to your site the best?
Check that your main SEO tags are unique (Title, meta descriptions…). Google penalizes sites whose tags are duplicated.
Track your site's performance (page load speed, number of pages crawled per day, etc.). With this information, you can easily improve the user experience.

Google is not stingy with advice to help you improve your performance. Do not hesitate to follow his recommendations.
