How to track directory listing to enquiry for Reddit Ads

Architecture

The exact event sequence

Five stages. There is no browser session anywhere in the first three stages. The measurement has to be built at intake, in your own system, or it cannot be built at all. The identifier has to survive all of them.

1. Step 1

   Directory listing viewed

   On the directory's domain. You will never see this event; the directory may report it.

2. Step 2

   Enquiry submitted

   On the directory's form. Still not your property.

3. Step 3

   Lead delivered

   By email or API, usually with the directory named somewhere in the payload.

4. Step 4

   Lead qualified

   Directory lead quality varies enormously between directories and is the whole reason to measure this.

5. Step 5

   Job or deal won

   The only stage with money attached.

Diagnostic sequence

What's specific to Reddit Ads

The funnel logic above is the same wherever you advertise. These are the parts that change because it's Reddit Ads.

1. 1

   Click identifier: the rdt_cid click identifier

   Reddit appends rdt_cid to your landing page URL, and the Reddit Pixel keeps its own identifier in the _rdt_uuid cookie. Reddit's audience is unusually privacy-aware — ad-blocker and tracker-blocker usage on Reddit traffic runs well above the web average — so the share of visits where the pixel never loads at all is higher here than on any other network in this list. The URL parameter is the identifier that survives; the cookie often does not.

2. 2

   Import mechanism: the Conversions API

   Server events posted to Reddit's Conversions API with the click identifier and hashed customer information. Reddit's implementation is younger than Meta's and its documentation moves — confirm the current endpoint, event names and required fields against Reddit's own developer docs rather than an integration blog post.

3. 3

   Deduplication

   The pixel and the Conversions API event must carry the same conversion identifier for the same action. Because so much Reddit traffic never runs the pixel at all, a lot of accounts skip the pixel entirely and send server-side only — which is a legitimate choice here in a way it rarely is elsewhere, and it removes the deduplication problem completely. Decide deliberately rather than running both and hoping.

4. 4

   Window and timing

   Reddit's default attribution windows are shorter than Meta's and are configurable. Check what your account is set to before reconciling anything, and verify the accepted event-freshness limit for server events against Reddit's current documentation.

5. 5

   The Reddit gotcha

   Reddit converts on a delay and on trust. People read a thread, leave, think about it, and come back through a branded search a week later — which is a genuine Reddit-driven conversion that Reddit will never be credited for and Google will happily claim. If Reddit is judged purely on last-click inside its own window, it will always look worse than it is. Build the measurement, then argue about attribution with that context on the table.

Source-of-truth validation

How to prove the chain works

One real journey, followed all the way, then a reconciliation. Neither on its own is enough.

• A live Reddit ad clicked, and the identifier confirmed present on the landing URL.
• The same identifier confirmed on the enquiry in your CRM or inbox after a full real journey through every step.
• Job or deal won confirmed arriving at Reddit Ads, verified by the events received and matched in Reddit Ads Manager, reconciled against your own records.
• Your crm, with the directory source recorded at intake reconciled against Reddit Ads per record over a fully closed window.
• The same reconciliation repeated 30 days later.

Straight talk

When this doesn't apply to you

Worth checking before you build anything, because two of these are common and both mean the work isn't worth doing.

• If you are not paying for directory placement, tracking this tells you something interesting and changes no decision.
• If you are not running Reddit at meaningful spend, skip it. And if your Reddit strategy is organic community presence rather than ads, none of this applies — that traffic has no click identifier by definition.
• If your cycle from click to job or deal won regularly exceeds the import window, the final event can't drive bidding whatever you build. Optimize toward tagged enquiry count per directory instead and use the later data for budget decisions rather than for bidding.
• If almost none of your directory enquiries carry a click identifier today, that's the whole project. Fix capture first — the import is the easy half and no tooling rescues a record with nothing to reference.
