Hi digital marketers, this is Salamin. In this video I show you the Reddit Pixel setup (browser-side tracking) for eCommerce events using Google Tag Manager (GTM) — step-by-step. Reddit changed their Ads Manager interface, so I start from the new Event Manager area and focus only on tracking (not campaign setup). I copy the Pixel ID, install the official “Reddit Pixel” GTM template from the Community Gallery, and fire the base PageVisit on All Pages to confirm the pixel is attached correctly. After the base pixel is working, I set up key eCommerce events like Add to Cart and Purchase with the right parameters. I create a constant variable for the Pixel ID (so you don’t repeat work), then pull currency, value, and transaction_id from the dataLayer. For Purchase, I also track total quantity using a Custom JavaScript variable so it works even when someone buys multiple items. I test everything using Tag Assistant + Reddit Pixel Helper and show how to verify events inside Reddit Ads Manager. One important truth: if you don’t set up a catalog on Reddit, you can see 0% match rate/coverage even when your events are firing perfectly. And my recommendation is: for browser-side, don’t overdo advanced matching—use hashed email/phone when possible, and I’ll cover the full server-side Reddit CAPI setup in the next tutorial for cleaner attribution.
