Audience Targeting and Retargeting

Core audiences are built using Meta's own data about its users: demographics such as age, gender, and location; interests inferred from page likes and content interactions; and behaviors like purchase history and device usage. Core audiences are the starting point for reaching cold prospects who do not yet know your brand.

Uploading a CSV file of existing customer email addresses or phone numbers to Meta creates a custom audience matched against Meta profiles. This allows you to run win-back campaigns for lapsed customers, cross-sell campaigns to specific segments, or exclude existing customers from prospecting campaigns.
