Today’s MarketingGoogle says Performance Max needs 15 conversions in 30 days to stay stable
Google’s Performance Max troubleshooting help page now says a campaign needs at least 15 conversions over 30 days for stable performance, PPC Land reported on November 8. Google says meeting the threshold helps ensure consistent spend and strong ROAS. The page also warns that delayed conversion data can cause spend spikes or low ROAS before the system recovers. PPC Land notes the page leaves open which conversions count and at what level they are measured.
Our take
Small and lead gen accounts now have a written number to plan around. If a campaign logs fewer than 15 conversions a month, merge campaigns or add a higher volume step such as a qualified form start so the bidder gets enough signal. Fix slow offline uploads too, since late data shows up as spend swings you will blame on the algorithm.
