Reddit ads show zero conversions because rdt_cid attribution only survives about 28 days in the browser — and it dies completely the moment your buyer checks out on a different domain. For considered purchases that close weeks later, Reddit never sees the sale even though it created it.
Why 'My Reddit Ads Show Zero Conversions' Happens
This is the classic discovery-channel trap. Reddit is where buyers research, compare, and ask honest questions — it opens far more deals than it closes. The gap appears because of how Reddit attribution technically works:
- Short Attribution Windows: Reddit's click identifier (rdt_cid) lives in a browser cookie that expires or gets cleared long before a 30, 60, or 90-day sales cycle completes.
- The Checkout Domain Break: If buyers complete payment on Stripe Checkout, a payment link, or a third-party portal, the Reddit pixel is not loaded there and cannot observe the purchase at all.
- Cookie Blocking: Safari ITP, Firefox ETP, and ad blockers delete or block Reddit's tracking cookies for a large share of visitors, so the click and the sale were never connectable in the first place.
The result: you keep buying Reddit ads that "don't work," pause the campaigns that were actually filling your pipeline, and the buyers keep coming anyway — unattributed.
| Attribution Layer | What It Sees | Where It Breaks |
|---|---|---|
| Reddit pixel + rdt_cid cookie | Same-browser, same-site conversions within days | Cross-domain checkout, cookie clearing, 28-day window |
| UTM tags in analytics | Sessions, not verified revenue | Last-click bias, no server verification of payment |
| Seatext Deep Conversions | The full 90-day journey from rdt_cid click to verified Stripe receipt | Nothing — the journey is persisted server-side and payment-verified |
How to Give Reddit Its Real Credit
- Capture the Click Server-Side: Record every rdt_cid arrival in a server-side journey record, not a browser cookie.
- Persist the Journey for 90 Days: Keep the click identifier attached across repeat visits, sales calls, and domain changes.
- Verify the Payment: Only emit a Purchase event when the payment provider itself (e.g. a Stripe webhook) confirms money moved.
- Report Back to Reddit: Send the verified conversion to Reddit attribution with the original rdt_cid intact, so campaigns optimize toward buyers, not clickers.
Deep Conversions persists a signed 90-day buyer journey from the first Reddit click and reports each verified Stripe purchase straight to the ad platform with the original rdt_cid intact — no spreadsheets, no CRM uploads.

How long can Reddit attribution survive?
Reddit's native rdt_cid cookie typically supports short windows measured in weeks. Deep Conversions extends the connection to a full 90-day signed journey held on the server.
Does this work if I use Reddit for lead gen, not ecommerce?
Yes. The verified purchase or signed-deal payment is reported back to the original click, so discovery channels finally receive credit for revenue they created.
Will a discussion upvote be counted as a conversion?
No. A Purchase event only exists after cryptographic payment verification (a completed Stripe session webhook). Engagement can never fabricate a sale.
