Best way to grab likes is put a badge on your website and if people will like your website, service or product then they will automatically like it.. Don't waste money or time in buying likes.
That's right you don't want likes. You want other people to see it, when it is like. The other people being the likers facebook friends.
+1, this really works. Also your content for likin should be SM-optimized, that means, good for the public, intriguing, not to sophisticated. People like amazing pictures and shocking news rather than usual content on your website
