Lookalike Audience Seeds
Select and size the seed customer list behind a lookalike, similar, or value-based audience - which customers to upload, how many, and whether the matched count (not the row count) clears the platform floor - with RFM and value-based selection, a negative-selection pass, a privacy and consent gate before any customer list upload, and a fallback ladder when the floor cannot be cleared. Use whenever the user mentions a lookalike or similar audience, a seed list, a customer list upload, match rate, an audience that is too small, or says their lookalike isn't working - even if they never say 'seed'. Covers B2B and B2C. Do NOT use to design the whole targeting tier structure - use mbfinotti/advertising-skills@ad-audience-targeting instead.
