You’ve just set up Google Search Console and submitted a sitemap but you check back a few days later and there’s no traffic being logged?
In this case, check which URL you are using. With the introduction of HTTPS and the change to no longer requiring WWW in the website address, there are four possible addresses you can setup as properties in GSC. To find the one with the most traffic, try this search in Google:
For example, I would type https://www.google.com/search?q=site%3Alanguedoc121tech.fr.
This then shows me that the WWW version of my site is the one getting the most traffic, so this is the one I need to log and monitor in GSC.
Armed with this info, delete any other URL variations you have setup in GSC and then add the one that comes up in the search you just ran.
Bingo! Soon (there’s a delay of course) you’ll have traffic.
You can also resubmit the sitemap to speed things up.
