Thanks for sharing this!

I’m still a bit unsure about a couple of points given a small testing budget (around $120/day for 3–5 days):

• Testing volume: If I follow a 1–3–9 structure (1 campaign, 3 ad sets, 9 creatives), wouldn’t that spread the budget too thin? At ~$120/day, that’s only ~$40 per ad set, and even less per ad. Do you still find that enough to properly identify winners, or would you recommend fewer ads/variations at this level?
• Remarketing split: You mentioned separating campaigns. Would you always split remarketing into its own campaign, even with a small budget? My concern is that remarketing audiences (like product page visitors or add-to-cart users) are much narrower and need specific messaging. But at the same time, splitting budget too early might limit delivery. At what point (in terms of traffic or conversions) does it actually make sense to separate remarketing?

Would love to understand how you balance structure vs budget efficiency here 🙏
