CPM (cost per thousand impressions)
Last updated 2026-06-14
Definition
CPM, or cost per thousand impressions, is what you pay each time your ad is shown a thousand times. Divide spend by impressions, then multiply by 1,000. It measures the price of reach, not clicks or sales. Quri reads CPM per campaign across your ad sources so you can see when buying attention gets more expensive.
How to do this in Quri
- Connect your ad sources so Quri can read spend and impression counts.
- Quri computes CPM per campaign so you see the cost of reach at a glance.
- Compare CPM across audiences and placements to find cheaper attention.
- Set an alert so a rising CPM surfaces before it quietly drains your budget.
Frequently asked
- Why does my CPM change week to week?
- CPM moves with auction competition, seasonality, and audience size. A jump often means more advertisers bidding for the same people. Quri’s alerting flags the shift so it is not a month-end surprise.
- Is a low CPM the goal?
- Not by itself. Cheap impressions to the wrong audience waste money. Read CPM together with CTR and CPA, which Quri shows side by side, to see if cheap reach converts.
