It's a lot simpler than you think. Not sure if this has been posted before but since I can't find it anywhere I'm posting it (it's a common method). You can use xrumer or manual posting (a LOT better for this.) 1. Search the forum for your content/relevant content on your topic. For example search for anything on weight loss on the forum via google. for example: site:http://www.ocf.berkeley.edu/~wwu/cgi-bin/yabb/YaBB.cgi weight Even though they're all physics things it will still count as slightly relevant so post a relevant answer on the post (to weight loss). 2. In your post make a smiley (default smiley like the forum has like this): And make it link to your site. 3. BOOM! relevant content backlink to your site from a good forum.
