Build a Google Ads search-term waste and negative-keyword agent with Claude

Write a one-page operating charter for search-term waste and negative-keyword governance before exporting any data. State the exact decision this workflow supports: which search terms should become negatives, remain monitored, or be promoted into intentional keyword coverage. Define the in-scope business units, pipelines, regions, date window, record types, and exclusions, then name one analysis owner, one Google Ads data owner, and one final approver. Record the review cadence as weekly and specify where evidence, approvals, and exceptions will be stored. Review the charter with the approver and do not proceed until the scope and decision rights are accepted.

Convert the operating policy into a rule register that can be checked against Google Ads campaigns, search terms, assets, and conversion actions. Create one row per rule with rule_id, rule_name, business_reason, required_fields, calculation_or_test, pass_condition, exception_code, severity, owner, and policy_version. Start with these minimum checks: terms are reviewed in context of the triggering keyword and campaign, conversion and value data are checked before exclusion, match type is chosen to minimize false positives, brand, competitor, support, and jobs policies are explicit, and every applied negative has a rollback record. Give every rule an example that should pass and an example that should fail so reviewers interpret it consistently. Have the business owner approve the rule register and record any unresolved policy questions before data is scored.
