you can use facebook ad campaign, adwords ad campaign to generate traffic for the page, if they really like your page, they will definitely like, if you feel that this idea is a crap. thanks for sharing the information.
If you are lloking for real fans that you want to monitise then I agree with several other people here, don't buy cheap likes, these will not be real people, get Facebook ad set up, it's easy to do and you can set your budget really low if you don't have a lot of money. Regards Polly.
If you want to increase your facebook fan page, you should copy the link to your forum and refer to someone who would like to earn. It's like promoting your online store by doing back links.
Be creative, I got huge numbers to one of my fanpages by setting up a quiz where people had to 'like' my page to partake. If you make the quiz title snappy and appealing enough to pique people's interest it'll spread around facebook like wild fire.
Yes, inviting all your friends and their friends. Fiverr is also a good place for getting likes. About 400 from a trusted gig.
No is not really a blackhat method. they are no bots involved, they are just people who like your page in exchange you will like their.... you may also add a like button on your website, or if you just want likes (for SEO,etc) just buy an large package of 1000-2000 likes.
there is no any other way to increase your likes of the facebook page.Your likes will automatically increase if you will post a quality content or ask ur frinds to like
