Ah! YES!! here’s a little secret: the best campaigns don’t look explosive, they look stable.
A PMax campaign is learning efficiently when your impressions and clicks grow steadily (not erratically), and your cost per conversion starts fluctuating less than ±20% week to week.
You’ll also notice conversion lag (the time between click and purchase) shrinking, that’s a great sign the algorithm is finding the right users faster. Instead of obsessing over daily results, zoom out and review rolling 14-day performance windows.
The trend you’re looking for isn’t speed, it’s predictability. When your metrics begin to even out and your ROAS stabilizes, you know Google’s model has “graduated” from guessing to understanding. That’s when scaling becomes safe and sustainable.
