My kill rule paid for itself in one week: $610 saved Set a hard line: any creative hits 3x payout in spend with zero conversions → dead, no debate. Last week 9 creatives tripped it: — payout $22, so kill at $66 spent — 9…

Killed CBO, went island bid caps — CPA dropped 31% Monday, $400/day account, CBO dumping 70% into one fat ad set. Tuesday I broke it apart: — 6 ad sets, own daily budgets — bid cap $14 (target was $18) — turned off the a…

Kill bad creatives at the thumbstop, before they ever cost you a conversion. Waiting for $0 conversions to judge a creative wastes 3x payout per dud. Early leading signal: 3-second view rate / hook rate. If under ~25% on…

How to know you've hit your scaling ceiling BEFORE ROI tells you: ROI is a lagging signal. CPM is the leading one. As you scale, the platform reaches deeper into less-qualified inventory → CPM creeps up step by step. Whe…

Why your CPMs spiked after you 'scaled' — you're bidding against yourself. Launched 4 lookalikes, CPM jumped 30%, ROI tanked. Classic audience overlap. When 2 ad sets share 25%+ of the same users, you auction against you…

Your breakeven ROAS is wrong if you ignore refunds and chargebacks. 2.0 ROAS feels safe → then 12% refund + 2% chargeback eats it and you're underwater you never saw. Real breakeven = gross breakeven ÷ (1 − refund rate −…

Campaign-budget vs ad-set-budget: the call that wastes the most money. Campaign-level budget (CBO) is great for SCALING proven winners — it hunts the best set automatically. Ad-set budget (ABO) is for TESTING — guarantee…

How I test 8 angles on $200 without lighting cash on fire: Not $25 each — that's 8 campaigns all stuck in learning, none getting signal. Instead: 1 campaign, 8 ads, let the algo allocate. Cheap, brutal, fast → it kills 6…

Finding your true bid floor: walk it DOWN, not up. Everyone starts low and raises till volume comes. Backwards. Start at a bid you KNOW wins auctions → get volume → then lower in 10% steps every day delivery holds. The s…

You're cutting on ROI when you should cut on margin dollars. Campaign A: 180% ROI, $40/day profit. Campaign B: 120% ROI, $300/day profit. ROAS-brain says kill B. Bank account says protect B. When budget's tight, cut by a…

One kill threshold is amateur hour. Tier it. Here's my 3-tier on every creative: — Soft watch: 1.5x payout spent, 0 conv → flag, don't touch — Throttle: 2x payout, 0 conv → cut budget 50% — Hard kill: 3x payout, 0 conv →…

Creative fatigue isn't about CTR dropping. It's about frequency × first-time-impression ratio. CTR can hold while you quietly burn the same 30% of the audience. Real fatigue signal: frequency climbing AND your reach curv…

Your dayparting is wrong because you're reading click time. Most buyers cut hours by when clicks come in. Dead wrong. Clicks at 9pm → conversions land 1am after the user 'sleeps on it.' Cut 9pm and you kill the 1am money…

Winner found. Duplicate or raise budget? Here's my call: Raise budget on the existing ad set → keeps learning data, but the algo re-enters a mini-learning wobble every big bump. Duplicate → fresh learning phase, burns ca…

The 20% scaling rule is a lie they sold you. Everyone parrots 'raise budget 20% every 3 days.' On a stable campaign that's leaving money rotting. What actually matters: how deep your audience is, not a magic percent. Bro…

3am, woke up to a blown daily, here's why: Overnight my CPA crept from $22 to $38 and I didn't catch it → cap drift. The trap: you watch CPA as one number. It's two trends fighting — early-day cheap clicks vs late-day ex…
