The short answer
A CPM of about $30 per thousand impressions, give or take $5 to $10; anywhere from $20 to $40 is fine. It is the least important of the six numbers that matter, but it is the earliest signal you get, and a $200 CPM means something is wrong before a single lead has arrived. When it is high the cause is almost always the creative.
Nobody should run a campaign off CPM. It is the cost of a thousand impressions, and impressions are not leads. But it arrives before anything else does, which makes it a useful early read on whether a new campaign is going to work or not.

| CPM | Reading |
|---|---|
| $20 to $40 | Fine. Stop looking at it and look further down the funnel. |
| $40 to $60 | Worth a look. Usually a creative fatiguing or an audience Meta is struggling to find. |
| $100 and up | Something is wrong, and it is almost certainly the creative. |
| $200 | The example from the video. Nobody needs a second metric to know this campaign is broken. |
Why the fix is the creative
CPM is the top of the funnel. At the point Meta charges for an impression, nobody has clicked, landed, filled anything in or spoken to a rep, so none of those things can be the cause of a bad number. What is left is what the ad looks like and who Meta can find to show it to, and in this market the second is mostly a function of the first: the creative is the targeting. A high CPM is Meta telling you the ad is not stopping anyone, and the response is to make more and better creatives rather than to fiddle with audiences.
It is worth being clear about what a good CPM does not tell you. A campaign at $22 can still be producing leads at $80 and funding nothing, because everything that decides that happens after the impression. CPM being in range earns you the right to look at the click-through rate, and no more than that. The full list of six is ordered that way deliberately.
It cuts the other way too, and our own main campaign is the example. In the seven days to 5 September 2026 it spent $18,452.78 on 379,634 impressions, a CPM of $48.61 (18,452.78 ÷ 379,634 × 1,000): above the band, in the worth-a-look row. The same week it produced 767 qualified leads at $24.07 each. That is one campaign in one week, measured rather than a benchmark, and it is the case for reading down the list before reacting to the top of it.
