How to get real facebook page likes?

Hi BHW,
I got a facebook page in a good niche that I'm sure will have plenty of likes. I've seen related pages with really active people and would like to get likes to my page too. I post interesting things and tried to comment on popular pages related to my niche like posting an interesting pic in the comment of post created by those popular pages and comment on it like "Like our page if you wanna see more of these." but still no likes.
Is there some kind of bots that do such kind of spamming? How do you get real people like your page?
Please help.

THeres a lot of different methods, offer something free like a tool, software, or ebook in exchange for a like, that could work, try and test, until you find something that works then expand it.
I've found I get a good response from sending direct messages on Twitter asking to exchange Likes, so I began running a few dozen twitter accounts in FollowLiker to scrape users in the niche and auto send the dm for me. I have most of my automated settings set low with longer time delays as most of these accts are fresh, but I still get around 40-50 likes a week on autopilot. Almost, I should say, as every couple of days I do login to FB and reciprocate the favor to hold up my end of the deal . That's another way, and it works for my workflow, but it all depends on what you feel like doing and not doing, and how much you want to succeed and how much you don't

Thank you Spinethetic,
My niche is about entertainment, vines community funny stuffs. I'm thinking but can't find what I can offer for free to people to like the page. But I'm still looking for something that will help me get them likes. Hoping that I'll come with a good idea.

As your niche is about entertainment/vines/funny things, then try to post as much funny vines/viral clips/create funny memes about celebrities (ex: Poot lovato haha) as you can on your page. You can also try to comment on famous page "as your page" with some funny comments/pictures (make sure your comment will be top comment so more people will notice it) to get people attention so they may like your page ^^

Thanks Ahnrie,
I think you just said what ive been missing: making the comment top so everyone can see it.
I use to comment on other pages related to mine but i guess they didnt get seen by lot of people.
So is there a bot that makes a comment top one?
