Campaign · Mass Tort Glossary
Also known as: custom list audience, first-party audience, uploaded audience
A Custom Audience is a targeted ad audience built by uploading a first-party data set—such as a list of prior claimants, website visitors, or CRM contacts—to an advertising platform so that ads are served specifically to those matched individuals. In mass tort campaigns, plaintiff firms and their media buyers use Custom Audiences to retarget people who visited a case-specific landing page, suppress existing signed retainers from ad spend, or reach known users of a recalled drug or device. Proper use reduces wasted impressions and improves cost-per-signed-case metrics by focusing budget on audiences with demonstrated relevance to the tort.
Mass Tort Ad Agency manages claimant-acquisition campaigns built on the concepts in this glossary — transparent cost-plus-15% pricing, in-house CloudIntake qualification, and chain-of-custody on every signed retainer. See the torts we run or book a strategy call.
