With the CPM pricing model, you’ll get paid based on the number of impressions an advertisement gets (in other words, how many visitors see the ad). If you generate a lot of website traffic, this pricing model will work in your favor. If your audience is smaller but more engaged, the CPC pricing model can deliver better results. Instead of receiving income for the number of impressions, the extra income that you earn is based on how many times a visitor clicks on an advertisement.
