Track your top-up experiments to find the best time window and measure real ROAS
How to use: Since GMV Max is a blackbox with no bid control, manual top-ups at specific times of day are your main lever. Top up a fixed amount (e.g. $10), note when it depletes, record orders and revenue. After 5–6 tests you'll see which time window converts best for the least spend. Set your gross margin below to calculate your breakeven ROAS.
