Facebook.
Facebook is one of the most visited websites in the world, as I had posted on the 11th of January, social network is great for exposure and indirectly increasing the search rankings.
I am going to create a facebook account and edit some basic information such as website, location and such.

Here you can see a screenshot of my facebook page. It is new, so I don't have any contacts yet, but I have already become a fan of a SEO expert, and I will be posting more news and information on it.
I have also made my url more user friendly.
