Max Conversions *can* work on a new account, but only if your conversion tracking is 100% correct.
With zero data it usually spends weird / hunts blindly for a few days.
What I’d do:
- start with Max Clicks (or Manual CPC) for a short “data” phase + add negatives + clean search terms
- once you get some real purchase conversions (even 10–20 is ok), switch to Max Conversions
- after it stabilizes, then test tCPA / tROAS if you have consistent volume
So yeah the “clicks first, then conversions” advice still works in 2025 , just don’t wait forever. The main thing is good tracking + clean traffic.
