What the heck?!?!

One of my shortest and most insignificant posts has brought obscene amounts of traffic to my blog. Apparently people searching for “happy” or “happy image” on the web are being directed here. I’m baffled and I don’t know whether to embrace it or remove the post. I would have hoped that this increase in traffic would yield more readers/followers/comments, but an audience looking for “happy” isn’t interested in a blog about being Bipolar. So what should I do? Has this happened to anyone else?
