What is CPM and when does it matter?
CPM stands for cost per mille (mille is Latin for thousand). It is the pricing model where you pay for every thousand times your ad is shown, regardless of whether anyone clicks it. It is the standard model for display, video and brand-awareness campaigns, and it works very differently from the pay-per-click model most people are familiar with.
What CPM actually means
When you buy CPM advertising, you agree a rate per thousand impressions. If your CPM is GBP 5 and your ad receives 100,000 impressions, you pay GBP 500. You pay that whether 100 people clicked or none did. This is the fundamental trade-off of CPM: you are buying visibility, not action.
The platform counts an impression each time your ad appears on screen. On the Google Display Network that could be a banner on a news site. On YouTube it could be a skippable video ad. On Meta it could be a sponsored post in someone's feed. Different placements command different CPM rates because the audiences and attention levels are different.
When CPM makes sense
CPM works best when your goal is reach and awareness rather than immediate action. A new business launching in a local area wants people to recognise the name before they ever search for it. That is a CPM job. A brand running a Christmas campaign wants to stay top of mind across hundreds of thousands of relevant eyeballs. That is also a CPM job.
CPM also suits remarketing. Someone who visited your site but did not buy is not likely to click a search ad for your brand again straight away, but a display ad that follows them around the web keeps your name visible. When they are ready to buy, they remember you. Remarketing display campaigns typically cost less than search clicks and can deliver strong overall returns.
Where you pay to play
The downside of CPM is that you pay regardless of performance. A badly targeted display campaign can burn through budget with nothing to show but a high impression count. That is why CPM campaigns need good audience selection, good creative, and a realistic view of what awareness is worth to your business.
CPM rates vary widely. A niche B2B display campaign on premium sites might cost GBP 15-25 CPM. A broad Meta reach campaign might cost GBP 3-8 CPM. YouTube bumper ads (six-second, non-skippable) sit somewhere in between. The right benchmark is what one thousand relevant impressions are worth to your conversion funnel, not the lowest rate you can find.
CPM vs CPC vs CPA
CPM buys visibility. CPC buys visits. CPA buys results. Each model has its place in the funnel.
Top of funnel (awareness): CPM. You want as many relevant people as possible to see your brand. You accept that most will not act immediately.
Middle of funnel (consideration): CPC. People know who you are and are now researching. You want them to visit your site.
Bottom of funnel (conversion): CPA or a target ROAS model. You only pay when someone takes the action you want.
