Tradedoubler Tracking Not Working? How to Verify and Fix Attribution
To verify Tradedoubler tracking, click your link in an incognito window and check: (1) the merchant URL contains tduid — Tradedoubler's click identifier, and (2) the click appears in your Tradedoubler dashboard within minutes. If clicks register but commissions don't follow, the problem is usually downstream: the merchant's site strips parameters before its tag runs, consent banners block the tracking script, or the program's attribution terms changed.
How Tradedoubler attribution actually works
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.
The 60-second verification
- ▸Open an incognito window (ad blockers and stale cookies corrupt the test).
- ▸Click your link and watch the redirect: it should pass through tradedoubler.com, clk.tradedoubler.com, pdt.tradedoubler.com.
- ▸Check the final URL for tduid. Present = the click registered; absent = inconclusive (many merchants clean URLs after storing tracking), escalate to the dashboard check.
- ▸Confirm the click in your Tradedoubler reporting within a few minutes.
- ▸If clicks never appear: regenerate the link. If clicks appear but conversions never do: test again with a consent-accepting browser profile, and review the program terms.
What silently kills tracking
- ▸Merchant-side redirects (https/www/locale rewrites) that drop query strings before the tracking tag runs.
- ▸Consent managers that never fire the merchant's tracking tag for visitors who don't accept cookies.
- ▸Visitors' ad blockers — some block affiliate redirects entirely; you can't fix this, only measure around it.
- ▸Program-side changes: program closed ends attribution even though links keep redirecting.
Frequently asked questions
Is a missing tduid proof my Tradedoubler link doesn't pay?
No. The click registers server-side at the Tradedoubler hop before the merchant page loads, and many merchants strip parameters from the visible URL afterwards. Present = proof of success; absent = check your dashboard.
Can I monitor Tradedoubler tracking automatically?
The redirect-chain and parameter portion, yes — Afterlink validates it on every scan and flags chains that stop passing through Tradedoubler's infrastructure. Conversion-side attribution is only visible in your Tradedoubler reports.
