I own a pretty popular blog online, and I was looking to get more traffic using a SEO plugin for my wordpress blog. There are a bunch of them online, but I don't know which one is the best.

I've been looking around, and I found one called Keyword Winner. I went ahead and purchased it after reading a review that I found online... let me know what you think about it..
