It helps, but you have to look around various forums to determine which ones to target. You should try to target relevant forums to your niche ad then pillow off a few non-relevant that can boost your authority. You should check to see if you can get dofollow links, though most forums nowadays set up their forum so only nofollows are posted unless a moderator changes it.skiwee wrote:Is really blog comments help to increase page rank?
If you run into a forum with all nofollow links, what I try to do is work on youtube embeds. Youtube embeds will help with the ranking of the YouTube videos and no one blinks an eye if you use those on a forum as long as the video is useful and relevant to what the forum members are looking at.
