Questions

m19, answered.

Is BidBison better than m19?

Neither is universally "better" — m19 offers a profitability-led machine-learning split aimed at both small sellers and professional/agency users. BidBison focuses on goal-based automation with expert-built playbooks and a target-ACoS autopilot. Which fits depends on how you want to work.

Is BidBison's automation "AI"?

BidBison uses automation and rules-based logic behind explicit, statable outcomes like a target ACoS — we don't lead with an AI label because the outcome, not the mechanism, is what matters to your account.
