An additional benefit to referral traffic is the fact that it gets people talking more about your web site on forums, web sites, and other areas. Which actually helps your Organic Traffic. It helps because most search engines check to see how many web sites are linking to your web site. So the more sites that link to yours, the higher your site will be in the search results. Which means more free traffic to your site. This was especially effective for my A.W.Surveys web site.
Don't forget about the power of E-mail as well in getting more traffic to web sites. If you are able to send out a monthly news letter for your site, you can always add in other web sites where you can receive Referrals from. Other way to do is add in another web site that you own to drive more traffic to it. The synergy by this makes my other web sites more popular as well. This is where Small Business Stacking comes into play as mentioned in the Core Theories, this is very important!
