Cold-traffic ad sets on Meta: $33.44 cost per purchase at 1.06 frequency
Commentary byROASArchiveOur analysis, not theirs@runtraffic shared a Meta Ads Manager screenshot of cold-traffic ad sets.
The top one ran at a $33.44 cost per purchase with a frequency of 1.06 and spent $36,681.69. A frequency that low means most people saw the ads about once.
It is a single snapshot from one unnamed account, with no control.
- Cost per purchase: $33.44. Whether that is profitable depends on the order value and margin, which are not shared.
- Frequency: 1.06. On average each person reached saw the ads just over once, so the campaign was still finding new people.
- Spend: $36,681.69 on a $5,000 daily budget. A second ad set in the screenshot ran at $37.50 per purchase and 1.09 frequency on $9,300.44. Not shared: number of purchases, ROAS, audience setup or the time period.
The change
Before
Not shared. The post shows the cold-traffic ad sets as they ran, with no earlier period or comparison.
After
Meta ad sets aimed at cold audiences for an ecommerce brand, reported at a $33.44 cost per purchase and a frequency of 1.06. That ad set spent $36,681.69 on a $5,000 daily budget.
Our reading: why it likely worked
Our interpretation, not the advertiser's claim.
- A frequency near 1 suggests the audience was large enough that Meta had room to keep reaching new buyers.
- Low frequency on cold traffic also means little ad fatigue yet, so CPA may rise once the same people see the ads again.
- The post is useful as a reference point for cold-traffic CPA, not as proof that one audience setup beats another.
Caveats: This is one campaign from one account with no control or before period. Purchase count, dates and attribution window are not shared, so we can't judge how stable the $33.44 is.
How to run this in your account
- Hypothesis
- If we keep cold-traffic ad sets broad enough that frequency stays near 1, then cost per purchase will hold steady because Meta keeps finding new buyers instead of repeating ads to the same people.
- Primary metric
- CPA
- Guardrails
- Frequency
- Spend
- ROAS
- Who should try it
- Ecommerce brands running prospecting on Meta with enough budget to reach large audiences. It tells you little if your market is small and frequency climbs fast anyway.
Questions
What is a good ad frequency for cold traffic on Meta?
There is no fixed number, but in this campaign frequency sat at 1.06, meaning people saw the ads about once.
It ran at a $33.44 cost per purchase.
Does low frequency mean lower CPA?
Not on its own. This post shows low frequency and a $33.44 CPA together, but with no comparison we can't say one caused the other.
