Here’s a simple little trick to find other sites that you can list your business on and have a link back to your own website.
Do a Google search on your keywords and location and then follow the links that come up, one at a time. For instance, if you’re a massage therapist, try typing in Massage Therapy <Your City Here> and see what comes up. Check each listing that comes up and see whether it is some kind of Massage Therapist directory – if it is then find out how to submit your business and do it right away. Systematically work your way down the list of search results and whenever you come across another business similar to yours, get yourself listed on the same site as well.
Try this tactic with a variety of keywords and get yourself listed on as many relevant directories as possible, and this will play a part in increasing your search engine rankings.
