I own a property management company and therefore I am not selling any products or services on a regional or national basis. I just need to increase the Page Rank for my main site to rank on the first page of Google for my primary keywords. I have been writing articles for my main site, posting them on EzineArticles and other article directories, and a little bit of social bookmarking. How can I use Facebook, Twitter, or Flickr for that matter to increase page rank? I do not see the value of driving traffic from a national audience because 99% will never have a need for my service. Thank-you in advance for your help. This forum has been very helpful to me.
