To continue the top lists for 2013 this one is all about referrals. A referral is a site where they reference my blog and their readers click the link to here. It could also be a comment I made on a post somewhere and it linked back to my blog. While search engines rule, you can see social sites like PlanetLotus.org, LinkedIn, Twitter, and StackOverFlow had some pretty good numbers. However, this supports the “content is king” motto when you see search engines with such a powerful referral number.
