AKN-London, can you give at least one good example of successful SEO campaign for facebook?
I only saw big brands that ranked well for keywords, most likely it's because they market their facebook like any other website.
In my experience, facebook doesn't give you much link juice specificly to your page. So it is very little value to have a page there for SEO purposes.
I think Squidoo and Hubpages will give you much better perks in terms of SEO.
