Facebook can be the most lucrative marketing activity you ever do for your business, but the problem is that most people spend $50 on a couple of ads, then get discouraged and quit when those ads fail to create a positive return on investment. But, these people aren't giving Facebook ads a chance to succeed, because they aren't doing nearly enough testing to figure out how to create the right kind of ads on Facebook.

It's simple: The more data you have about ads -- how they work, how much you should spend and more -- the better you can understand the market and the better you can market on Facebook in the future. So, don't just run a couple of ads and then quit. Instead, be willing to take the time to test what works and what doesn't.
