If you don’t know, advertising is a broad umbrella to cover, and both costs per click and pay per click are two of the most primitive types of advertising that most businesses look forward to.
Although both types of ads are flexible and only cost when someone clicks on the ad, the basic line of difference is because of the advertising module.
Such as, cost per click (CPC) advertising depends on the impression you have to pay according to the number of times the ads are shown to your targeted audience.
On the other hand, the cost per engagement or pay per click (PPC) is a type of advertising where you have to pay when someone clicks and engages with your ad.
