Getting good backlinks to your site is key with real estate being one of the most competitive online verticals there is. The links will help your search engine rankings. Just any old link from another site is not good enough you need to focus on related sites and getting a link that will pass value to your site. This is not in the form of a banner or footer link but needs to be on a page with content and should have relevant link anchor text. Link anchor is the text or term that you would like your site to rank for. Real Estate Knoxville is an example of link anchor text if you are looking to have your site rank for that term. Link anchor text should not always be the same, linking needs to look natural so sites linking to you will not always use the exact same anchor text. Think of terms you might like to rank for "Knoxville Housing" "Knoxville real estate agent" and so on - Don't under estimate the power of inbound links - even a well placed base link can be worth a lot in terms of SE rank and traffic.
