Tradedoubler parameter
What is the tduid parameter?
tduid is Tradedoubler's tradedoubler click id. tduid is Tradedoubler’s click identifier, appended to the merchant URL and consumed by the merchant-side tag. In decade-old European content, checking for tduid behavior is the fastest live-or-dead test for Tradedoubler links.

How Tradedoubler tracking fits together
Tradedoubler links pass program (p), affiliate (a), and ad (g) IDs through clk.tradedoubler.com, optionally with a url destination. On click, Tradedoubler registers the event and forwards with a tduid click identifier.
Tradedoubler has operated since the dot-com era, so European content archives are full of its links — many pointing at programs that no longer exist. Old-content audits find more dead Tradedoubler links than any other European network.
