i just want to know if its good for visitor loyalty, getting more visits, etc. is it effective? have you seen some results?
I strongly suggest adding the open graph like buttons. There are a few advantages: 1) When someone likes your page, it get's broadcasted to all of their friends AKA free publicity 2) There is no way this won't be an SEO factor at some point. What's more relevant to how good a page is then how many people physically vote for it?
If you've got good content and your users aren't afraid to share it should work. After all that's what it's for right? Also I've seen a a few pages that are liked just check otu the buy sell forum they have about 5 likes. It does work but it might nto be easy. I have a like site and it has gotten well over 200 likes. You just got to know how to encourage people liking it also it doesn't help my traffic was facebook targeted traffic.
