I have a big following on Facebook and Twitter but want to improve on my incoming traffic from Google and Yahoo search engines to my entertainment website.

What are some ways of getting my Facebook fans to do the work and boost my pagerank, search engines credibility, alexa ranking, etc. for my website?

(I know that being linked to on other popular sites increases your page ranking but how would I get my social following to help get my links out there in a big way?)
