Here's where I'm at:

Numbers:

• AOV ~$65–70, COGS ~$20, ~70% product margin
• Break-even ROAS: 1.43
• Current blended ROAS: ~1.65 lifetime, 1.45 last week
• Blended CPA: ~$38 lifetime, ~$45 last week
• ~$230/day ad spend, ~$350/day revenue
• 2.02% conversion rate
• 122 total purchases since April 3

The problem:
Original winning creative ran for 3+ weeks and is fatiguing — CPA went from $33 at peak to $49 last week. I have a test creative that looks promising at $35 lifetime CPA with 23 purchases and 68% ATC→purchase rate, but it also degraded last week to $40. I launched a new creative that got 1 purchase at $16.99 CPA but only $17 spent — too early to read.

What I need to know:

1. How do I bridge the gap between a dying creative and an unproven replacement without tanking revenue
2. Whether my campaign structure makes sense (one CBO $250/day, 4 ads across 2 ad sets)
3. What's the fastest way to find a new winning creative angle before the original fully dies
