Another tidbit from SEO land

Another way to get traffic for free is from other sites in your niche. Getting links with other sites in your niche is also good for SEO, especially if you manage to get links without the famous nofollow attribute. But even if the links are nofollow (i.e. they are useless for SEO), they still help to get traffic to your site. If you manage to put your link in a visible place on a site with high volumes of traffic, you can get thousands of hits from this link alone. If you need list of sites within your niche where you could get backlinks from, check the Backlink Builder tool. However, be careful if you exchange links because linking to bad neighbors can do you a lot of harm.
