Using forums for SEO

Forums are online communities where people come together to discuss similar subjects. When you leave useful comments on forums, you can usually place a small link back to your business web site. Doing so will help to increase your link popularity.

If your web site is for example about cooking, just go to Google and type down "cooking"+"forum" and hit Search. Google's search results will then show you all the forums that you could possibly imagine and participate in.

Good luck!
