What Is a Walled Garden in Digital Advertising?
· 1h ago · Originally reported by PPC Land
A walled garden refers to a digital advertising platform that controls its own user data, ad inventory, and measurement tools, limiting access to outside parties. Major platforms like Google, Meta, and Amazon operate as walled gardens, keeping their ecosystems closed to external measurement and data sharing.
Why it matters
Understanding walled gardens is important because they shape how advertisers can target audiences, measure campaigns, and access data, impacting transparency and competition in digital advertising.
Explain it like I’m new here
It's like a playground where only the owner decides who can play, what games are allowed, and who keeps score.
