Publisher Site 2

User browses to this second publisher site where ads are being served via publisher ad server

The advertiser (Tealium client) creative that loads has the Tealium tracking pixel embedded.

The tracking pixel makes a request to Tealium's 'databridge' cookie service, and writes the data tracked in the query string params.
