So Facebook changed how their ad system works about a month ago... long story short, they found an excuse to charge more for clicks and impressions. In addition, they stopped maximum bid for CPC and replaced it with "target bid." Overall, this priced me out of being able to use Facebook advertising for the target audience I wanted. But I found a bit of a loop hole. If you use the "boost post" function, not only can you include more text in your "ad" but it seems to run in a similar way to the old facebook ad system. So for anyone that is getting priced out of facebook advertising, try the boost post function as a replacement for ads, it has been performing very well for me. Cheers!
