You can open up many more options by developing a blog that works in conjunction with your site. Obviously it is the power of the blog content that brings in fresh visitors on a consistent basis from which you will benefit. It is more than possible to create an incredible marketing funnel that leads right to the door of your membership site. You will have a golden opportunity to allow your readership to become friends with you, and that is a good thing. What about Facebook and Twitter? Do not avoid bringing those elements into the mix on your blog. Once your blog is up and running along, then you will see how much impact this will have on your membership site.
