Define the target-account denominator
30-60 min
30-60 min
Freeze the account list, parent-subsidiary rules, geography, employee-size bands, and eligible audience definition. Reach is meaningless without the denominator. Work from LinkedIn Ads using campaign group, campaign, audience, company name as the minimum evidence set. Complete this work in LinkedIn Ads or the controlled working file; no Claude prompt is needed for this step. Save the finished artifact in the account penetration matrix with the run date, owner, evidence reference, confidence, and approval status. Treat privacy thresholds as a separate exception class and do not count it as failure unless the policy says so.
Define the target-account denominator completed as a dated section of the account penetration matrix, with campaign group, target-company reach, evidence links, owner, and approval status for expand under-reached accounts.
Do not let campaign group stand in for campaign; that shortcut creates false positives in company reach and audience penetration. Document the result in the same run folder so the next cycle can compare like with like. Apply it specifically during “Define the target-account denominator.”
