What is rdt_cid?
What rdt_cid does
Reddit Pixel reads rdt_cid on destination pages and attributes the click back to the Reddit Ads campaign. Same architecture as Meta Pixel + fbclid.
Reddit Ads matured later than its competitors (the modern ad-targeting platform launched around 2019). rdt_cid is therefore relatively recent — most Reddit-Ads-attributed click tracking pre-2019 ran via the older promoted-post mechanism without URL-based identifiers.

Frequently asked
Is rdt_cid the same as fbclid?
Same shape (per-click identifier added to outbound URLs), different ad network. fbclid for Meta; rdt_cid for Reddit.
Did Reddit Ads always have rdt_cid?
No. It came in with Reddit's modernised ads platform around 2019. Earlier sponsored-content systems didn't use URL-based click IDs.
Clean tracking on iPhone, in one tap.
LinkClean strips ~80 vendor-specific tracking parameters from any link, from any app's share sheet — and preserves functional ones like hl, t (YouTube timestamp), and q (search). No account, on-device.
