To implement audience-based targeting, start by defining who you want to reach based on factors such as location, demographics, interests, search behavior, past interactions, and customer data. Then choose an advertising platform that supports the audience signals you need.
For example, Google Ads can use audiences, remarketing, customer lists, in-market segments, and demographic signals to refine targeting. LSA works differently and relies more on service, location, and local-intent signals rather than traditional audience targeting.
Once campaigns are running, compare audience segments by qualified leads, conversion rate, cost per customer, and revenue. Keep the audiences that produce valuable customers and adjust or remove segments that generate poor-quality traffic.
