Bid Duplication: What It Is, Key Features, Benefits, Use Cases, and How It Fits in Programmatic Advertising
Bid Duplication is a common (and often expensive) inefficiency in **Paid Marketing**, especially within **Programmatic Advertising** where auctions happen in milliseconds and the same impression can be offered through multiple paths.
