I've been using WordPress for less than a year, but I've blogged on different services for many years, here and there, and never successfully.
What I like about this Bizxpress tool is that it makes it possible to do real SEO for my WordPress sites.
I like the incredible amount of information that you get in the keyword research. The included training takes a long time to get through, but it's so different than most of the other stuff I have bought online that it is worth it to me to go through each step and get this different point of view.
Using this plugin has already changed my WordPress experience (for the better) and I feel I feel like I have more control over my sites.
