Frequency

How many times the same person has seen your ad, averaged across an audience. Over ~3 in a 7-day window, CPMs rise and CVRs drop — the fatigue signal.

Frequency is the average number of times a single person has seen your ad over a defined window (typically 7 days). Once average frequency climbs past ~3 on a 7-day window, you'll usually see CPMs rise and CVRs drop — the same audience becoming repeatedly exposed to the same creative.

Frequency is a better fatigue signal than raw ROAS because it catches the decay early. If frequency is climbing and CPMs are stable, you're still OK; if both are climbing, you're running out of net-new eyeballs with this creative and it's time to refresh.

Fixes: rotate in fresh creatives; expand the audience; cap frequency at the ad-set level (particularly on retargeting, where 2-3 views max is the humane rule).
