European affiliate network
Tradedoubler Affiliate Link Checker
Tradedoubler links (clk.tradedoubler.com) are among the oldest affiliate links still live on the European web, which makes them disproportionately rotten: programs closed years ago keep receiving clicks from old content. Live links break via program closure or dead destinations; attribution rides on the tduid click ID.
How Tradedoubler links work
Typical link
https://clk.tradedoubler.com/click?p=12345&a=6789012&g=345678&url=https%3A%2F%2Fmerchant.com%2FproductTradedoubler 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.

How Tradedoubler links break
Program closed
Clicks land on error pages or get bounced to merchant homepages. Multi-year-old links are frequently dead this way.
Destination rot
The url parameter targets pages restructured away years ago.
Ad-level expiry
Links tied to a specific ad ID (g) can die when the ad campaign is retired even if the program lives on.

How Afterlink checks Tradedoubler links
Afterlink extracts every link from your YouTube channel or website, recognizes Tradedoubler links by domain and parameter signature, then runs five checks on each one: the full redirect chain (including JavaScript and meta-refresh redirects), network error-page detection, destination verification against the embedded target, tracking parameter analysis, and deep-link decay detection (product page silently replaced by a homepage). Every link gets a clear verdict — working, warning, or broken — with the evidence attached.
Frequently asked questions
Are my old Tradedoubler links from 2018 still paying?
Verify rather than assume: check the program is still live in your Tradedoubler account and that the link reaches a working destination with a tduid attached. In old content the honest answer is often no.
What is pdt.tradedoubler.com?
A Tradedoubler tracking host used in product/data-feed links, alongside the clk.tradedoubler.com click domain. Both are legitimate Tradedoubler infrastructure.
