CPMs creep up for almost every advertiser over time. In 2026, more competition and tighter delivery mean the cost to reach a thousand people keeps rising. The good news is that CPM is not fixed. Most of what drives it is in your control.
What actually drives your CPM
- Audience competition, especially in saturated niches and peak seasons.
- Creative quality, since ads that earn engagement get cheaper delivery.
- Account trust and history, which shape how the auction treats you.
- Relevance and feedback, where hides and reports quietly raise your cost.
The levers that bring CPMs down
- Ship stronger creative that earns real engagement instead of scroll past.
- Give Meta room with broader targeting so it can find cheap impressions.
- Run on an account with genuine trust and history.
- Keep a warm pixel and consistent activity rather than stop start bursts.
- Watch frequency so you are not paying more to hit the same people.
Why account trust sets your floor
Two advertisers can run identical creative and pay very different CPMs. A trusted, aged account gets cleaner delivery and better auction treatment, while a fresh or flagged account pays a hidden tax through worse placement.
If your costs feel stuck no matter what you change in the campaign, the account underneath is often the real ceiling. Running on aged, trusted infrastructure removes that drag before you even touch the creative.
