I avidly post guest blogs on Xanga to drive traffic to my websites. These guest blogs are usually posted in the hot areas of Xanga (their gaming section, as well as the men's section), and the traffic boost lasts about 1 weeks. During this time my traffic usually doubles or triples, in some cases I get my own personal record breaking traffic. Sadly, none of the visitors from Xanga seem to click ads.
I don't know how many of you actually try to utilize Xanga, but I thought I would throw out my personal experience with using the guest blog feature and how well it works. (or doesn't in this case)
