Should You Kill This Ad? A Simple Decision Tree for Contractors.

The 5-question checklist that tells you whether to kill, optimize, or keep running an underperforming Meta ad.

The hardest decision in Meta ads isn't launching — it's killing. Most contractors hold onto underperforming ads too long, bleeding thousands before admitting it's broken. Here's the 5-question decision tree.

Step 1: Has the ad had enough spend to evaluate?

Under 1,000 impressions: Too early. Keep running.
1,000-5,000 impressions: Noise. Let it continue unless CPL is 3x+ target.
5,000+ impressions: Enough data. Proceed to step 2.

Step 2: Is CPL 2x+ your target?

CPL within 30% of target → Keep. Normal variance.
CPL 30-100% over target → Optimize. Review creative + audience; consider pausing in 7 days if no improvement.
CPL 2x+ over target → Kill. Don't wait.

Step 3: Is the ad rejected or flagged?

Ad rejected → Kill this version. Rework copy/image, relaunch as new ad.
Delivery flagged 'low' → Usually means poor relevance or budget/bid imbalance. Optimize first; kill if no fix inside 5 days.

Step 4: Is the creative fatigued?

Frequency under 2.5 → Not fatigued yet
Frequency 2.5-3.5 → Approaching fatigue. Prep replacement creative.
Frequency 3.5+ → Fatigued. Kill and replace.
CPL rising >20% week-over-week AND frequency above 2.5 → Fatigue-driven. Kill.

Step 5: Is the ad part of a winning combo?

Sometimes a single ad looks weak but it's the 'supporting cast' that helps your winning ad close. Check: is this ad driving retargeting traffic? Video views that feed retargeting audiences?

Ad generates top-of-funnel reach feeding retargeting → May justify lower CPL. Evaluate full-funnel contribution.
Ad exists in isolation (no downstream funnel) → Apply kill-rules directly.

When in doubt: kill faster than you think. The cost of a killed-too-early ad is tiny vs. the cost of a kept-too-long ad.

Frequent Questions. Short Answers.

What if my CPL is high but close rate is great?

That's a case to keep — the lead quality compensates for higher CPL. Calculate cost per booked job instead of CPL alone. A $40 lead that closes 25% ($160/job) beats a $20 lead that closes 8% ($250/job). Metric matters.

Can an ad be 'revived' after pausing?

Rarely works with the same creative. Better: pause, wait 30+ days, relaunch as a new ad (different thumbnail, different opening seconds). Same ad resumed after pause usually performs worse than the original run.

Should I tell my agency to kill underperformers?

Your agency should be doing this automatically. Weekly creative reviews + 7-day pause thresholds should be standard. If your agency is running creatives 60+ days without pausing any, they're not optimizing — they're just running campaigns.

What if everything is underperforming?

Stop scaling. Take a step back. The issue isn't individual ads — it's the account-level strategy (offer, audience, landing page, funnel). Use our Account Health Score tool to diagnose where the foundation is weak.
