Hi there guys I have a male enhancement site that is on the third page for it's main keyword. I also have started a classifieds site that is just starting up but is already getting about 10 posts a day. Google is crawling the classifieds site well and has already indexed about 200 pages or so. I was wondering if I should put a backlink on the footer of every page of my classifieds site linking out to my male enhancement site. That way, I have a backlink every time someone posts a ad in my classifieds site. I am just worried about the content though. They are obviously not even closely related and I would have to put the link somewhere in the bottom where people don't notice it. The enhancement site serves the U.S. and the classifieds site serves India. So, they don't match even in that sense. Will this affect either of my sites in a bad way. Will Google penalize me for this and will these backlinks help my SERP's. Sorry about all the questions but it was hard to find an answer for a situation like this. Will be grateful for your opinions.
