The Leaks Are Not Where You're Looking 

Paid accounts typically run with several small problems at once. Irrelevant search terms eating spend, audiences too broad to convert, creative that's been live too long, landing pages losing people after the click, and measurement setups making all of it look fine. 

Any one of these is manageable. Together, they compound into an acquisition cost that quietly makes every campaign underperform. 

Where You Should Be Looking 

The fastest ROAS killers are usually the following: 

• Search term waste: broad match terms pulling curiosity traffic while high-intent terms sit underfunded. Check your search term report for high spend, zero conversions. 

• Audience dilution: loose geography, weak exclusions, no first-party data layering. Platforms will keep finding impressions even when audience quality drops. 

• Creative fatigue: falling CTR and rising CPA usually mean the ad has been seen too many times. Refresh before it becomes a problem, not after. 

• Landing page friction: slow load, poor mobile UX, too many form fields. Many media problems are actually conversion problems in disguise. 

• Measurement gaps: duplicate conversion tracking, wrong attribution logic, no separation of new versus returning customers. Bad measurement trains the algorithm on the wrong signals. 

Key Takeaways

Small leaks across targeting, creative, and measurement compound fast 

Search term waste and weak negatives are the quickest fixes 

Poor campaign structure drifts budget toward easy impressions, not valuable ones 

Landing page friction kills ROAS as fast as bad targeting does 

Bad measurement trains automation toward the wrong outcomes 

Fix the leaks before scaling the spend
