I Killed Three Ad Audiences After One Honest GA4 Look - digital marketing guide from Tech Revenue Brief

CTR looked fine. Spend looked fine. Pipeline looked like a polite shrug. So I opened GA4 without the ad-platform glasses on.

Export your last 28 days of converting users. See which audiences actually appear in paths. Pause anything that burns budget and never shows up. Rebuild from purchasers and form-submit events before you invent another lookalike.

What the report said

Three audiences drove clicks. Zero showed in purchase paths. They were expensive tourists.

I kept the audience built from trial starts. I killed the "interest" stack that felt smart in the ad UI.

The boring rebuild

  1. Purchasers (180 days)
  2. People who hit pricing twice
  3. Newsletter subscribers who clicked a product link

That's it. UTMs stay clean — see the UTM builder if your tags are still freestyle.

What I tell clients

If Meta or Google loves an audience and GA4 never mentions it, believe GA4 until proven wrong.

Cut the tourists. Feed the buyers.
