Wasted ad spend. How we detect it

Zero-ROAS keywords, fatigued creatives, and audience overlap.

3 min read•Updated April 3, 2026

Ad-spend leaks are the single biggest dollar category in the median Omesta customer. Three detection patterns do most of the work.

Zero-ROAS keywords (Google Ads)

Keywords that have spent more than $50 in the last 30 days with zero attributed conversions, and whose historical 90-day conversion rate is also zero. These are almost always safe to pause. Median saving: $340/mo on a $10k/mo spend.

Creative fatigue (Meta, TikTok)

Ad creatives whose 7-day CPA is more than 40% above their 28-day baseline while frequency has climbed past 4.0. We flag creative to rotate, not pause. The audience still works, the hook is just burnt out.

Audience overlap

When two ad sets targeting the same audience are bidding against each other, you're paying Meta twice. We detect overlap above 28% and flag the ad sets to consolidate.

Each finding ships with a one-click "apply fix" button (if you've enabled autopilot) or a copy-and-paste workflow to execute manually.
