I'm not sure Facebook 'Like' have any SEO benefit since it is a Javascript/iFrame load and Facebook doesn't control a search engine, therefore they have no clout in search. I would always recommend people to Like my Facebook page for engagement b/c people on Facebook like to stay on Facebook - so if you give them news and updates on Facebook, they're more likely to see it and engage with it. On the flip side, I have heard Google +1 does have some minor SEO benefits though I'm not sure if they're going by raw +1 counts or if it's only relevant if someone within your circles +1 the site. (e.g. it'll show up 1st or 2nd in your search results if someone you know +1 a site with a topic you're searching on.)
