You don't advertise in forums and groups. You contribute by asking and answering questions. If you create a compelling signature file and you show up in the forum a lot people will click on your link.

Another way to get traffic is through Article distribution. You can write articles and distribute them to lots of different article directories such as Ezine Articles and many others. With articles you again include a good signature file. This is a good way to get traffic, you just have to be willing to write.

You can also post articles on Squidoo which does allow more room for advertising.

Another good place to post articles is at Digg.

Traffic exchanges is another way to get free or low cost traffic to your website. An example of this is Traffic Swarm.

You can also get involved in social networks like Facebook, Friendswise, myspace and there are many others.

And still another great way is to create a blog just like this one. There are many places where you can get a free blog. WordPress.org and Drupal.org are a couple of great places to go to creae a blog.]]>
