I do not backlink. I am really at a loss as to how. I also like being semi-anonymous here, so I don't tweet, FB or anything like that. I have yet to join Pinterest and can't decide if it's even a good idea.
On the other hand, I am not raking in the bug bucks, LOL. So far my best month has been about $3.50. I'm at about $5 right now for March, so I'm feeling super successful.
Maybe I should try backlinking but it makes my head hurt to think about it.
