Facebook Page Likes

I am struggling with my Facebook page likes. I have selected niche related Audience, Age, Interest for Facebook page Ad campaign but did not get appropriate results . Please give any suggestions for increase my Facebook page likes.

there are tons of cheap likes for sale on fiverr and here on the marketplace.
personally, I only want likes on my pages that are from same industry type of pages OR same city based users. I feel that too many likes from random and foreign sources is a waste of time.
What is your page about? Maybe I can give you a better idea how to get some legitimate likes instead of crappy ones.

Did you use facebook ad and not getting enough likes? You can create new profile that attracts people and use it to promote your page. Also you could use free like-exchange services.

I have one real estate page and one digital marketing page. The response rate was very low after ad campaign. I already invest lots of money to boost my Facebook page likes but did not get response. If any blackhat technique please suggest. I have already tried lots of tools for increasing FB page likes but all of these are useless.

using the facebook page advertising will usually end up costing you about $3/like in my experience. This just isnt a good deal and your money will go fast. There are easier ways to get likes on your page, the easiest of which is to make connections in social groups of similar people and exchange likes with them, or simply post something worthy of them liking it. So for real estate pages you should join REESAS, Activereain, Zillow, etc. as each of them has a large social community which is good for getting Likes.

PM me your page and I will give you a Like.

Why do not you target to niche related groups?Believe me,this will give one perfect boost and better engagement.Just Stop your ads for a week and try it.
Else,
Share informative content on your page and share it with people,you will find some good number of likes.
