Performance Max
Performance Max is a Google Ads campaign type that automatically distributes ads across Google's channels using supplied assets and goals.
In detail
You supply assets, audience signals, feeds and a conversion goal; the system decides placement and bidding. Visibility into query-level detail is limited.
It depends on accurate conversion data — with poor tracking, automation optimises towards the wrong thing efficiently.
Example
Running Performance Max alongside branded search campaigns, with brand terms excluded so results are readable.
Why it matters
It can broaden reach cheaply, but only when measurement is trustworthy.
Common mistakes
- Launching it as the only campaign with no search baseline.
- Letting it absorb branded traffic and claim the credit.
