alot of pharmacy site contains viagra, cialis pills but they have been around for alot time, I do not know think it is the subject of the contents that cause the site to be deindex, it is something else, which i cannot figure out
If deindexed its because it was banned most probably. The reason, if not because the content, maybe because some bad practice. Readd Google TOS.
Did you or anyone else remove it in webmaster tools? The site still has its PageRank which doesn’t happen for a site that isn’t indexed. Give it a few days and see if it comes back. Thanks Brian
Google possibly removed it due to spam or it got penalized for some bad SEO practice. What have you been doing in regards to SEO?
