This system attempts to artificially increase the ranking of other sites in our search results. This artificial ranking favours irrelevant results over the requests of Internet users, which contravenes the Google guidelines for webmasters. Therefore, we have decided to give less credit to links from your site. The manual action for spam has been applied specifically to domaine.com/.
To resolve this issue, please correct the links by following the instructions below and then submit a request for reconsideration in the Search Console. We will cancel the manual action applied to your website once the Google Search Quality team has determined that the issue has been successfully resolved.
