both of us all know the forum signature is a good way to get the backlinks, but how can you do this best and how can you avoid to be banned ? and I always see many forums put many pictures ADs in above or below the post, how can I do this? if I want to do this, should I must contact with the Administrator?
Just look at their rules and regulations. some forums may let you advertise and some may not. so, before doing something just know their rules.
yes...reading forum rules is the way to avoid ban...some of the forums allow links after certain amount of posts. If you are too early to put the links in signature, there are chances that you get banned..
first forums rules and regulation read than forum is dofollow or non follow, forum PR, popularity, hoe many daily online users. than start Forums posting some question ANS and even i have any question so i will post Question and get suggestion
