We have been managing PFN's SEO and marketing for about 4 years. They currently have several first-page listings on Google and Bing for various keyword terms. We manage the social networking on a weekly basis with Facebook, Twitter and their LinkedIn group as well created custom pages associated with those accounts.
We also created a custom newsletter area on the website which includes a tabbed layout so visitors have immediate access to 6 months of newsletters, a Featured Article, Featured Member, New Member "Shout outs", Newsletter archives and more! We created a matching HTML email template for the client to send out with Constant Contact each month to help bring members and visitors back to the site. We manage the entire newsletter and send-out each month. We are currently getting a 24% click-through rate!
