I've been doing a lot of work with a company called MemberPress lately. They are a fantastic membership plugin for Wordpress that enables you to create a membership platform and start making money from your content in no time. I would highly recommend them if you are planning on launching a membership site anytime soon.
I've been writing a series of blog posts for them about online marketing and the first one is out! It is about supercharging your membership site rankings with webmaster tools. If you'd like to read the full article, check it out here on their blog.
I'll keep this post updated with links to all of the posts I've done for them as they come out. Upcoming next...Google Authorship and Ranking Protected Content with Excerpts.
