Understanding Audience Overlap Analysis in Digital Advertising
· 2h ago · Originally reported by PPC Land
Audience overlap analysis is a method used to determine how many individuals are present in two or more audience segments. This helps advertisers identify duplicated targeting, assess the reach of new partners, and avoid running ads that compete with each other.
Why it matters
Knowing which audiences overlap allows advertisers to optimize their campaigns, reduce wasted spend, and improve targeting efficiency.
