Matched and custom audiences built from lists: retargeting, suppression and ABM targeting on every ad platform.
How a list becomes an ad audience: what each platform matches on, the pipeline from rows to a live audience, retargeting, suppression and ABM audience types, the hygiene that decides match rates, and the approval gate that belongs in front of every ad account.
Customer Match is Google Ads’ mechanism for building audiences from your own customer data - hashed emails, phones, names and addresses - across Search, YouTube, Gmail and Display. What it matches on, the policy and size requirements, and how B2B teams use it well.
A matched audience is an ad audience built from a list you own, matched by the platform against its members. The definition, what the platforms match on, the four audience types, and why the match rate is a data-quality score in disguise.
