Many advertisers wait until CPA jumps to realize something is wrong. By then the budget is already being spent less profitably.
Here’re the signals to watch for before your CPA moves.
Search: CTR drops on stable impression share. Your ads are still showing, but people stopped clicking. Check your top keywords’ ad copy first. If the messages haven’t changed in 60+ days, they’re probably stale. Rotate in fresh headlines and watch CTR recover.
PMax: Asset ratings sink from Good to Low before conversion rate falls. Don’t wait for the campaign summary to tell you. Pull your asset group performance report weekly. Swap Low-rated assets before they drag the whole group down.
YouTube / Demand Gen: Cost per View (CPV) rises while conversions hold. The platform is working harder to get the same watch. Swap the first 2-3 seconds of your video. A new hook resets the asset ID and gives the algorithm something fresh to test. Or, try new videos.
Start looking for these patterns. The platform will show you the stress before the numbers break.
Check these signals weekly. Get ahead of it and you’ll spend less on fixing fires and more on scaling what’s working.
