How to operate on Google Search
Operator playbook
- Separate brand and non-brand into different campaigns; never let PMax cannibalize brand.
- Use PMax for shopping/Discovery, manual Search for high-intent commercial queries.
- Bid on AI Overview-adjacent queries with structured snippets and explicit answers.
- Audit search-term reports weekly; PMax masks query-level data — request Insights tab exports.
- For DTC, run tCPA at portfolio level (not per campaign) — algorithm needs volume.
- Brand-bidding from competitors? Trademark exclusion via support ticket — Google enforces.
- Use offline conversion imports (OCI) for any sales-cycle longer than 24 hours.
- AIO-resistant queries: comparison ('X vs Y'), long-tail commercial, location-based, branded.
