Forums are a phenomenal place to get backlinks if you do it correctly. If you spam your hub in a post, the mods will just delete your post. If you find yourself a forum where the mods don't care and let everyone link out to anything, then your link won't help you.



You have two real options when it comes to getting backlinks on forums, you can use your signature line which is perfect since moderators usually don't throw a fit about the links people have in their signatures.



Your other option is to find a forum that is related to your hub. You'll want to make a few posts that aren't related to your hub -- just being friendly and replying to things people say. Then after you've at least made a small presence on the forum mention that "this article kind of describes how I feel BACKLINK_HERE." Just be respectful, no-one likes a spammer .



Looking for a forum? There are a huge number of forums all over the Internet. If you need help in finding a forum, I highly recommend making a quick Google search like "your_interest forum." All sorts of results will show up and you'll quickly find the perfect forum for your needs.



There are some things you have to look out for when selecting a forum. First, you'll want to make sure that the search engines can access the posts. This is easy. Just check and see if you can access posts on the forums without being logged in. If not, then the chances that a search engine has access the posts is slim.



You'll want to make sure the links in the forums are do-follow. There is a really handy free tool that will let you know whether or not a link is do-follow. You can find out about this tool (and other awesome SEO Tools) in my hub, Top 7 Free SEO Tools. <-- See that plug there, that's how you'll want to do it in the forums... nice and natural. :P
