Discovery needs guardrails
Broad match can surface useful variants, but only with enough signal quality and negative discipline. Without controls, it scales curiosity traffic faster than insight.
Treat discovery buckets as research programs, not permanent campaign homes.
Promotion criteria should be explicit
- Qualified lead outcomes, not just conversion event volume
- Consistent relevance between query language and ad promise
- Landing-page fit that sustains conversion quality under higher traffic
Phrase and exact are for ownership
Once a query proves commercial fit, move it into phrase/exact themes where copy, negatives, and pages can be tuned for that intent family.
Ownership reduces auction ambiguity and gives cleaner operational levers for bids and budgets.
Governance cadence
- Review discovery terms every week
- Classify terms: negative, monitor, or promote
- Apply promotion and blocking changes in the same cycle
- Track whether promoted themes keep lead quality as volume grows
