I checked to see if the site has been indexed by Google. In the Google search box, I typed: site:orlytaxis.fr [enter].
In the results, you'll see how many pages are currently being indexed by Google. When I did this, I received the following results:
This shows that Google sees 7 pages of your website. Do you have that many? Or, do you have more than that on your site? If you've added more and don't think they have been indexed, consider that you haven't published them yet. Also, do you have your site connected to Google Search Console (formerly know as Webmaster Tools) and Google (or some other) Analytics? Do you have the files: robot.txt and sitemap.xml submitted to Google?
These are some of the basics to check.
