Bounce tracking

Bounce tracking (also called link tracking) relies on adding parameters to URLs to transfer information across organizations. It is used by multiple supply chain partners for millions of websites, such as authentication providers, credit card verification, and even Google and Facebook to track clicks on advertiser links within Search and ads in their digital properties.

Both UID2 and Prebid SSO also rely on this technology to ensure user opt-in preferences can be communicated across the various sites people visit, despite the active interference by Internet Gatekeepers.
