CPM vs. CPC: Which is cheaper for Facebook ads?

Marketing changes as the market ebbs and flows, and so do you. CPC or Cost-Per-Click is a good option to start out, its the cheapest option to get yourself a good foothold in the market. CPM or Cost-Per-Impressions, is a better way to get more clicks, more reach, but is more expensive and works better when you have the follower count and profitability to justify it. This however is a general rule and some ad campaigns work better or worse depending on products and services.
