CPM (cost per mille)

CPM is the cost per thousand impressions: total spend divided by impressions, multiplied by 1,000. It tells you how expensive it is to reach people on a platform or with an audience, before anyone clicks.

Example: a campaign spends 600 SAR and gets 120,000 impressions, so its CPM is 600 ÷ 120,000 × 1,000 = 5 SAR. A rising CPM usually means more competition for the same audience, a narrower audience or a seasonal peak such as Ramadan or White Friday.
