How to Get More Likes on Facebook
1) Great Content Works
People like to follow Facebook pages because they get some value from it. Either they’re entertained or informed or get some other great satisfaction from it. If your fanpage is filled with content that is self-promotional rather than something that provides value to people, then you really ought to recognize this fact and make your content better.
2) Hold Some Kind of Contest
Many pages have held some kind of contest to get a lot more interaction and interest on their page. If the prize is compelling enough, people will go out of their way to interact with your page. This might lead to a rapid inflation of raw numbers, but not necessarily as much long term engagement unless you provide content that people want to stick around for.
