How much will it affect the pr of my website if I put my link in my signature of this forum.? As I know the pr of this forum is 7!
PR from the actual URL matters..Sigs would be from Threads and Posts..and the actual PR would be zero.. The link back would count.. and Real PR would be sent to your URL, however if u keep an eye on TBPR, it will not change.. No effect as such..Backlink will get counted though..
it gives just a very little percentage like what trichnosis said. just keep on doing this, still it helps you, their is nothing to worry about as long as you don't spam.
