It takes a lot of testing with custom audiences to get your price point low. Facebook is still one of the cheapest traffic methods I use.
i did both ways with custom and their choice with keywords but price is still way over normal
Poor Facebook owner needs moneywhy are the ads so expensive all of a sudden, the keyword is not that special, supposed to be about 60million users but they only give me 2,000 for 10$ min. cpm is more than 5$ that is insane
