A blended CPM can increase because delivery moved between countries, placements, audiences or days. It can also rise within comparable segments. Those explanations imply different actions. This audit keeps the business result visible so the team does not optimize for cheap impressions that never become useful visits or customers.

How to run the investigation
Rebuild comparable windows
Use equal weekday periods and consistent account currency. Record promotions, holidays and major account edits. Compare prospecting and retargeting separately so a shift toward a smaller warm audience does not look like a universal auction shock.
Separate delivery mix
Read spend, impressions, CPM and downstream outcomes by available country, placement and campaign breakdowns. Use native reporting when a requested breakdown is unavailable. Do not compare segments that have only a handful of impressions as if they were equally reliable.
Follow the outcome chain
Look at link clicks, landing-page visits and the chosen conversion alongside CPM. More expensive impressions can still produce a better cost per customer when relevance improves. Conversely, a cheap country can dilute the account’s blended cost while contributing no qualified demand.
Choose the next test
If price rose in a stable segment, review creative, audience constraints and auction context. If allocation changed, document the tradeoff before excluding a placement or country. Keep budget and targeting changes behind an explicit approval.

Use these rows to turn the investigation into an action. Add the actual account, date range, evidence and owner before sharing it with a client.
| What you find | Interpretation | Next move |
|---|---|---|
| CPM up, conversion cost down | More expensive reach may be valuable | Judge on the qualified outcome. |
| Country mix changed | Blended average is not like-for-like | Compare each country before changing bids. |
| CPM up and visit quality down | Several stages worsened | Investigate message, delivery and destination together. |

Worked example: an illustration, not a customer result
A hypothetical account shifts from mostly $5 CPM inventory to mostly $15 CPM inventory. Its overall CPM rises even if both local prices stay fixed. If the second market delivers the paying customers, reversing the shift to restore the old CPM would optimize the wrong number. Keep the client’s serviceable market explicit.

A question worth asking
What is a good CPM for every agency client?
There is no single useful threshold across countries, objectives and audiences. Compare the client’s own history and the economics of the outcome. A benchmark without those conditions is context, not a decision rule.
