There are plenty of companies out there offering all kinds of deals on facebook likes, e.g 1000 likes for $20 etc. But are they really of any value? I would say no as I doubt those thousand fake likes would have any interest in your facebook page, or your business.
Recently I was involved in the set up of a new website and part of that involved getting the facebook page set up. This site was specifically targeted towards 16-20 year old females, in the USA.
Using facebook adverts I was able to set up an advert that specifically targeted that age range, in that location and females. I could set my own bid price and set it at a maximum of 15 cents per click.
I managed to achieve this result for this facebook page
101 Page Likes for $21.69
I know I could have bought a fake package for a lot cheaper however I actually managed to get 101 likes from my target audience.
Anyway I am not going to go into the specifics of exactly how to set the adverts up, that’s pretty simple, just make sure you set your budget and maximum bid, otherwise you can burn through a lot of cash in short amount of time. And of course make it highly targeted to the audience you are trying to attract.
