what is backlinks? how does it work? I think I know this but now I doubt it and have others confusion in my mind.. let's say my new site has zero backlinks, then I order gig on fiverr that promise me some backlink (web 2.0 either social bookmark either blast etc), but later on I check my site there's not few of them.. WHY!? eg. ordered 100 .edu backlink. Check my site > 10 backlinks found.. didn't get index is it? is that the cause of the problem?
