Examples of Custom Audience

eCommerce Store: An online fashion retailer wants to target people who visited their website, browsed a specific product category (e.g., women’s clothing), and added an item to their cart but did not complete the purchase. Using Facebook’s Custom Audience feature, the retailer uploads a list of email addresses of those visitors and creates a targeted advertising campaign to entice them to come back and complete their purchase, offering a limited-time discount.

Event Organizer: A conference organizer seeks to promote an upcoming tech event to professionals who attended the previous year’s edition. Using LinkedIn’s Matched Audiences tool, the organizer uploads a list of attendees’ email addresses (with their consent) and creates a custom audience to serve personalized ads, providing early-bird discounts and highlighting speaker lineups to encourage past attendees to register again.

Local Gym: A local gym aims to target previous members who had canceled their membership within the last six months. The gym combines their CRM data – including email addresses and phone numbers of previous members – with Google’s Customer Match feature and creates a custom audience for targeted ads on Google Search, YouTube, and Gmail. Through this campaign, the gym promotes a special “welcome back” offer and highlights new gym equipment or services to entice lapsed members to rejoin.
