Wow it seems great traffic but your blog is hosted on blogspot, its a free domain so will it be worth buying?
I did it on purpose since it was originally created on blogspot service 3 years ago. If I change it to another domain Google might not like that + blogspot (blogger) is a service by Google so the SEO is wonderful ! Its highly recommended for advertising , the traffic is very quality and unique !
