Automated campaign types like Advantage+ generally perform well once an account has enough clean conversion data and a healthy creative rotation feeding them — they typically handle bidding and placement optimization better than manual setups at scale. They perform poorly on accounts with thin data, broken tracking, or a single tired ad running for months.
Trust automation for optimization mechanics, but keep manual control over inputs: creative quality, offer, audience exclusions, and budget pacing still need a human. Kando typically treats automated campaign types as the default starting structure, then intervenes on inputs rather than fighting the algorithm on bidding.
