Facebook ads are a lot simpler than people think. Facebook have made the service as easy as possible so that anyone and everyone can use it. Most seem to think it's a very complicated process when it really isn't. What does get complicating though is working out and optimising your ads for the best return on your investment. You want to be targeting the right people with the right ads. You also want to work out whether you want to go for CPC or CPM, both differ a lot.
