How to reconcile Reddit Ads against your billing system
This is the check we run first on every account, written out so you can run it without us. It takes about thirty minutes and needs two numbers: what Reddit says it produced, and what your billing system actually shows. The gap between them is the only honest measure of whether your tracking works — and if it comes back small, you do not need us.

Reddit vs new subscriptions: short windows meet long trials
Store rdt_cid on the billing customer at signup and send the first successful payment through Reddit's Conversions API with the subscription ID as the conversion ID. Compare against a closed month of first payments. Reddit reading lower than billing is normal for considered purchases; reading higher usually means a free account signup is counted as the subscription.
rdt_cid is the click identifier that can link a Reddit visit to a subscription row, provided it is captured on landing and written onto the customer when the account is created. Reddit audiences tend to research, sign up for a free tier or trial, and pay later, so the identifier has to persist from the first visit to the first invoice, often across devices. Hashed email helps only if the person subscribes with the email Reddit knows.
Reddit's default windows are shorter than Meta's and configurable, so check the setting in your account and in Reddit's current documentation. A fourteen-day trial followed by a first charge can fall outside a short click window entirely. Also verify how old a server event Reddit will accept before backfilling payments from billing, because a first charge arriving weeks after the click may be rejected.
Use Reddit's conversion reporting for the single paid event, not page visits or signups. A shortfall is expected: many Reddit-driven subscriptions return through branded search and get credited to Google instead. A Reddit total above your new subscriptions is a fault, and the common one is a sign-up event on the free plan carrying the paid plan's value.
Reddit × Subscriptions · what breaks
Why Reddit and your billing system disagree
- 01
Every renewal firing as a conversion
The single most common subscription error. A customer who stays two years produces twenty-four payment events, and counting them all inflates the conversion count by exactly your retention rate.
- 02
Trial starts counted as paid conversions
A free trial costs the user nothing. Optimising toward trials reliably finds people who start trials and never pay.
- 03
Cancellations inside the first period never reversed
Early churn on discounted offers is high, and the reversal is almost never wired.
- 04
Lifetime value assumed rather than measured
An industry figure for tenure will either starve a channel that works or overfund one that does not. Your own churn data says something different.

What each side is actually counting — Reddit × Subscriptions
- 1
What Reddit counts
An event name Reddit recognizes, a conversion identifier matched to the pixel if you are also running one, a timestamp, hashed customer information, and the click identifier where you have it.
- 2
How Reddit attributes it
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.
- 3
The window it uses
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.
- 4
What your billing system counts
First successful payments on new subscriptions, found in Stripe, Chargebee, Recurly, Paddle or whatever charges the card.
- 5
The filter that makes them comparable
New subscriptions only — exclude renewals, and exclude trials that have not yet converted.

Reading the gap — Reddit × Subscriptions
| What you see | What it usually means |
|---|---|
| 15%+ platform higher | Usually the wrong event entirely — the platform is counting renewals, trials, or subscriptions that cancelled before the first real charge. |
| 20%+ platform lower | Usually structural — the platform is missing subscriptions it produced — usually a signup-to-payment gap longer than the attribution window. |

Read the events received and matched in Reddit Ads Manager, reconciled against your own records
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.

Reddit × Subscriptions · when not to buy
When the answer is that you do not need us — Reddit × Subscriptions
- If almost all of your new subscriptions come from a channel with no click behind it, no tracking work will reach them — and knowing that is worth more than a build.
- 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.

FAQ
Reddit × Subscriptions questions, answered
Because they come back later through a branded search, and last-click credit goes to the final click. Ask new subscribers where they heard about you and compare that answer with Reddit's count.
Check what the account allows first. A longer window will credit more trial-to-paid conversions, but compare it against your billing data rather than accepting the higher number.
Because you should know the size of the problem before anyone quotes you for it. If the gap is small, you have saved yourself a purchase. If it is large, you now know what you are buying rather than taking our word for it.
No. Both numbers come from systems you already own and neither leaves them. There is no tool to sign up for and nothing to upload.
Then compare totals for a closed period and treat the result as directional rather than exact. The events received and matched in reddit ads manager, reconciled against your own records is still the right place to read the platform's side.
Under five percent is working. Five to fifteen usually means reversals are missing. Above twenty is normally the wrong event being counted, not a broken tag — which is why debugging tags first wastes so much time.
Then fix the filter before drawing any conclusion. New subscriptions only — exclude renewals, and exclude trials that have not yet converted. A mismatch in scope produces a gap that looks like a tracking fault and is not one.
