SandboxPenalty
 

Recently, my site has been penalized in Google search and this has definitely shocked me. I think that there are punishments for the changes in the sites. It is for the first time that I lost my location. There are of course several times that I have told about the pages to be indexed, especially when I did a search domain. Unfortunately, I could not find it in Google again. Currently, I have also lost some pages which have again surprised me, and I want to know how did it happen exactly? Is it because of the black hat seo techniques?
