If you’re a member of any forums out there, like audioholics.com for stereophile hobbyists, you can increase your blog or site’s promotional mileage by creating a thread that’s relevant to both your blog and forum and inviting members to visit your blog or web site.
Just be sure that your site covers the same interests that the forum does. If it’s about photography, your blog or site should have that as its main focus or anything related to it. You can also use the forum’s signature or avatar with your site’s URL as signature. This is one fine promotional method as your site gets displayed every time you post in the forum.
In the process, you leave your site’s URL link on the forum. This is one form of back linking to your site which increases its page rank in Google. If you can do this in a number of forums related to your site or blog, the better for your site.
