Yes, there is such a thing that if you start doing it yourself, then all your work may simply be in vain when your site will be in the search engines at the very bottom and will not be of interest to anyone .. at the moment there are many companies that do this professionally, for example: https://crowd-groups.com/en/2022/03/23/filter-google/
Therefore, if you have the necessary funds, I would look for professionals .. but I didn’t dare to do this myself ..-) good luck to you
