I'm wondering if anyone has an opinion on the value of adding your link in forums or blog comment threads. This has of course been a popular strategy for years with people offering to get you hundreds of links for a certain price. My instinct is that this sort of link building is very transparent to the search engines and will add minimal benefit (if not cause harm) to your rankings. In the right circumstances these links might send some relevant traffic I suppose- but I question how good they are for SEO.
