Australian tech company, in-house PPC team of 4.
We run AI max through an A/B experiment (campaign vs with AI max on) across half a dozen campaigns. Conversions are about +20% on control, CPA is between 10% better to 10% worse so overall better than I expected from what is essentially Broad Match on steroids.
We’re 4 weeks into the 6 week test but don’t expect results to differ much. 80% confidence interview puts the conversion uplift as a real deal.
Onto problem is that the early days had a lot of irrelevant keywords come up that needed heavy negative work
