I'd advise against buying any likes. Post reach on facebook pages have been cut to around 3%. So any thing your post on your page, only around 3% of your fans will see it by default now. If you have high fake likes, you are wasting the only chance you have at communicating with your real fans. If you are building nice sites, the like will come naturally. If you are building made for adsense junk, real or fake likes probably will not matter anyway.
Depends on who you buy from. If they are publishing status update to a large group of fans then it is very possible to gain a real fan base. If i were in the market I would look for people who are selling status updates in my niche and and avoid people selling exact quantity of LIKES. No one can guarantee that people will like your stuff so if they offer 200 LIKE for $10 and deliver they most likly are not going to convert well for you and your money will be better spent on a quality ad in a status update.
Yes,it is very good to have many likes on your page . It will create more traffic on your website and will also help you to get good ranking on Google...but one thing you have to be aware of is that likes you get should not be disappeared after some time.The most important thing is that your page should contain useful information and it will automatically attract people to like your page and your posts.
I do not think is a good thing to buy likes, they are real likes of people interested in your content. Don't waste your money buying likes that will not help you much.
I was thinking about buying likes on fb, but now i'm changing my mind.. how do you know they are real or fake? Maybe it's better to promote page by myself and find real people..
