Google's help page for **Performance Max** now says the campaign needs **at least 15 conversions over 30 days** for stable results, as reported on **8 November 2026**. Below that, Google says spend and results can swing. It is advice, not a rule: nothing says Google pauses a campaign below 15.

## What we know

The line sits on Google's page [Troubleshoot performance fluctuations in Performance Max](https://support.google.com/google-ads/answer/12200334), which we read on 9 November 2026. It says: "Achieving stable performance requires at least 15 conversions over 30 days."

- **Where:** reason 2 of 10, "Conversion tracking setup & conversion delay".
- **Confirmed:** the sentence is on Google's page today.
- **Reported:** [PPC Land](https://ppc.land/google-ties-consistent-pmax-spend-to-15-conversions-every-30-days/) says a June 2026 copy of the page had no such number and listed nine reasons, not ten.
- **Not stated:** whether the 15 count per campaign or per account, and which conversion actions count.

## What it means for your ad account

| Your Performance Max campaign | What Google's page implies |
|---|---|
| 15 or more conversions in 30 days | Enough data for steadier spend |
| Under 15 conversions in 30 days | Expect bigger swings in spend and [ROAS](/glossary/roas) |
| Sales that report days late | Spend can jump while data catches up |

Say you spend INR 60,000 a month at a INR 6,000 [CPA](/glossary/cpa). That is 10 sales, under Google's 15. Many small Indian and Gulf accounts sit there, and every edit restarts the [learning phase](/glossary/learning-phase) on thin data.

## What to do this week

1. **Count conversions** for each Performance Max campaign over the last 30 days in Google Ads.
2. **Check your tracking** with our [conversion tracking guide](/guides/how-to-set-up-google-ads-conversion-tracking), so no sale goes missing.
3. **Merge small campaigns** that each sit under 15, so one campaign gets all the data.
4. **Hold edits** for two weeks on campaigns near the line.
5. **Watch brand searches too,** since [Performance Max may now skip them](/news/google-pmax-may-filter-brand-searches).

## FAQ

### Will Google stop my campaign under 15 conversions?

No. Google's page calls 15 a condition for stable results, not a rule to run.

### Do leads count, or only sales?

The page does not say. It says "conversions", so the conversion actions you set as primary are the likely count.

### Is 15 new for Performance Max?

The number appears on the page now. PPC Land reports an older copy without it, but Google has not dated the change.
