Meta CPMs Keep Rising. Here's What Changed

By Thisura, founder of Run1Ads · 2026-07-12 · Updated 2026-10-28

Quick answer

Meta ads CPMs keep rising because delivery has become less stable, seasonal auctions are more crowded, and Andromeda rewards accounts with deep, varied creative libraries. In one r/FacebookAds thread, a long-running e-commerce advertiser reported CPMs rising from $5 to $6 to around $15 while impressions roughly halved between June 2025 and June 2026. The most durable responses are a steady supply of distinct creative and monitoring that catches delivery problems within hours.

A thread on r/FacebookAds has the receipts for what a lot of Meta advertisers have been feeling but could not quite prove.

An e-commerce brand that says it has run Meta ads for 14 years, spending well over a million dollars a year, pulled its June 2025 versus June 2026 numbers. It reported new customer acquisition down 30%, orders down 28%, sessions down 25%, impressions roughly cut in half, and CPMs that used to run $5 to $6 now regularly hitting $15 on the same ad formats.

The post picked up steady upvotes and a real comment thread within hours, which suggests many other accounts are watching the same pattern in their own dashboards.

What does a rising CPM mean for my Meta ads?

CPM, cost per thousand impressions, is what an advertiser pays Meta just to show an ad, before anything else happens.

When CPM rises faster than results do, you pay more to reach fewer people. New customer acquisition breaks first, because Meta's delivery system has less room to explore past an account's existing buyers.

Why is unstable delivery worse than a high CPM?

The account owner in the thread noted that before 2024, "off days" with delivery instability and sudden performance crashes happened two or three times a year. Now, they said, those days hit once or twice a week.

Each one erodes acquisition further, because the algorithm needs a stretch of stable delivery to relearn who to show ads to.

A single CPM spike is a cost problem you can budget around. A weekly pattern of unpredictable delivery is a forecasting problem. "Meta is having issues" used to be rare enough to notice. Now it is routine enough to plan for.

Why are Meta ad CPMs so much higher in 2026 than a few years ago?

Three factors compound each other. More frequent delivery instability forces the algorithm to keep relearning who to target.

Seasonal auction pressure from Prime Day and back-to-school budgets crowds the auction in summer. Andromeda's creative-based retrieval rewards accounts with deep, diverse creative libraries and penalizes accounts running the same handful of ads on repeat.

Accounts without a stable creative and delivery baseline going into busy seasonal windows tend to feel it hardest.

What should e-commerce brands do when CPMs spike but sales barely move?

The advertiser in the thread said sales fell only 2% despite the acquisition drop, because average order value rose 22% as they leaned on bundling. That is a real lever, but it is a patch, because it papers over a shrinking pool of new buyers.

The more durable response is to treat creative supply and delivery monitoring as the real growth levers.

Feed Andromeda a steady supply of conceptually distinct ad concepts, not just variations of one winning ad.
Use bundles and offers to lift order value, but do not mistake that for new customer growth.
Track new customer acquisition and cost per purchase separately from blended ROAS.
Watch delivery hourly so a collapse is caught within hours, not at a month-end review.
Retire aging ads as fatigue sets in, before they drag CPMs up further.

How do founders without a media buyer keep up?

For founders and operators who do not have a full-time media buyer watching the account, Run1Ads does the watching. It checks your Meta ad account, Pixel and store every hour and emails you when spend continues with no sales, so a delivery problem shows up early instead of in a quarterly review.

It also flags ad fatigue when aging ads start wearing out, then tells you the one fix to make first. It advises, you decide.

Meta ad costs are not just up, they are less predictable. Accounts treating that as a monitoring and creative supply problem tend to outperform the ones treating it as a bidding problem.

FAQ

Why are my Meta CPMs going up?

Less stable delivery, crowded seasonal auctions and Andromeda's preference for diverse creative all push CPMs higher. Accounts running a few ads on repeat feel it most.

Can I fix high Meta CPMs with bidding changes?

Rarely on its own. Creative supply and fast detection of delivery problems usually matter more than bid tweaks.

Does a higher average order value fix rising CPMs?

It can protect revenue in the short term, but it does not replace new customer growth. Track new customer acquisition separately so the pattern does not stay hidden.

Yes. Run1Ads checks your Meta ad account, Pixel and store every hour, flags ad fatigue and alerts you when spend continues with no sales. It advises only and never changes your campaigns unless you ask it for a paused draft.
