These days, there are online forums about almost anything. And a great way to drive traffic to your blog is through becoming active in a relevant forum.

The first thing you must do is find a forum that is directly relevant to your blog. After signing up to become a member, look for posts whereby you can add valueable insight or information. Make sure you add a signature, which includes a link to your blog. This way, each time you reply to a forum topic, your blog and link will be shown for free. This can get you traffic and also it can help increase your popularity in the search engines eyes.

Another way to take advantage of forums is to get hired from another website or blog to get paid to make forum postings for them. You can usually negotiate a rate whereby you get paid per forum post.
