I think that forum signature links are much more valuable than forum profile backlinks. It also helps if the forums are related to whatever you are link building for. This way they can actually bring you some targeted traffic that can convert as well as some indexed backlinks.
Forum signature links are awesome. It's the most effective free method for promoting your site, and building backlinks.
Yes, they are helpful but not so helpful, if you get a links from blogs on pr 3 then it is better than 10 forum links.
Links from discussion forums in your niche are really going to help you generate good backlinks for your website
They do help, esp as many forum threads end up ranking high in search engines. They are proven to increase your search visibility
I've read that they are very low value links. However, they are good for getting new sites indexed quickly.
As noted above and on other threads, a link is a link is a link, so yes they will help you. But they are not, IMO, of particularly high value. But if you enjoy the forums and like to help people, just keep doing that and they will build up. Just do us all a favor, I see what I consider to be spammy comments here as much as some blogs. If you're going to make a comment, try to be helpful, not just saying something really pithy like "I agree".
Forum Links are great i'm told.. I'm testing them out for my site. Hopefully will get traffic soon... Just takes time..
