Check whether your Reddit click context survives the landing page

Paste a public Reddit ad destination with rdt_cid and inspect the passive browser journey for Pixel activity and persistence signals.

Reddit ad landing URL

Paste the exact public Reddit destination URL with rdt_cid. We check the passive browser journey for Reddit Pixel and redacted click-context storage.

This tool answers: Does rdt_cid reach a Reddit Pixel and persist beyond the landing URL?

Enable JavaScript to run the check — the diagnosis itself is free and needs no account.

Why this happens

Reddit can record a click while your site fails to carry that context into a conversion. The URL may lose rdt_cid on the next page, the Pixel may be consent-blocked, or no first-party click context may be written at all.

A disappearing query parameter is not automatically a failure: a Pixel can capture it on landing and persist it safely. The useful question is whether the Pixel was actually observed while the ID was available.

These answer the questions this one tends to raise.

How this check works

So you can trust the result — and your developer can verify it.

  1. Read the supplied landing URL

    We require rdt_cid on the starting public URL, then record whether it is present at each observed journey step.

  2. Look for passive Pixel evidence

    The result identifies recognised Reddit Pixel requests and redacted Reddit-related storage keys. It never sends a conversion or accesses Reddit Ads.

Common causes and fixes

Pixel absent or consent-gated
If the pixel never loads while the click arrives, Reddit cannot receive browser-side landing context.
No persistence beyond the URL
A URL can be cleaned by a redirect or router before the next page. Storage or supported first-party integration is what makes the context durable.

Frequently asked questions

Should rdt_cid remain in every internal URL?
Not necessarily. It is normal for a URL to be cleaned after a Pixel safely captures the value; this check separates that from missing pixel evidence.
Can this prove a Reddit conversion was attributed?
No. It observes public browser signals only. Account-side matching and attribution need a controlled conversion test and Reddit reporting.

See paid-social context before it becomes a reporting gap.
