What CPM means
CPM is the cost of showing your ad 1,000 times. The M comes from mille, the Latin word for thousand.
CPM = (cost ÷ impressions) × 1,000. If ₹5,000 buys 100,000 impressions, your CPM is ₹50.
How to use it
CPM tells you how expensive attention is. It doesn't tell you whether your ads are working. A cheap CPM with no sales is still a loss, and an expensive CPM that brings the right buyers can be a bargain.
Use it to compare audiences and placements, then judge the campaign on cost per customer.
Why CPM changes
It moves with competition for the audience, the season, the placement, and how well people respond to your ad. Festival periods are often more expensive because more businesses are bidding for the same people.
