Google sets 15-conversion threshold for consistent PMax spend
· 2d ago · Originally reported by PPC Land
Google documentation indicates Performance Max advertisers need roughly 15 conversions every 30 days to sustain consistent spend, mirroring the bar already used for Search Target ROAS bidding. The guidance appears on an undated page, leaving open questions about which conversion types qualify and at what account or campaign level the threshold is applied.
Why it matters
Small advertisers running Performance Max may see budgets stall if they can't hit the conversion volume, so understanding the threshold helps them plan bidding strategy and set realistic expectations.
Explain it like I’m new here
It's like a video game that only lets you use the best power-up once you've scored enough points — Google wants to see enough sales before it spends your ad budget steadily.
