Reddit Pixel

Overview

The Reddit Pixel is a snippet of code you add to your pages so Reddit can see what visitors do, then use that data to measure conversions, build audiences, and optimize your Reddit ads.

The Pixel registers a PageVisit on every load, the Reddit equivalent of a Meta PageView. From there you can fire additional standard events like Lead or SignUp, or your own custom events, to mark the actions that matter to your campaigns.

Step 1: Get your Pixel base code

<!-- Reddit Pixel -->
<script>
  !function(w,d){if(!w.rdt){var p=w.rdt=function(){p.sendEvent?p.sendEvent.apply(p,arguments):p.callQueue.push(arguments)};p.callQueue=[];var t=d.createElement("script");t.src="https://www.redditstatic.com/ads/pixel.js",t.async=!0;var s=d.getElementsByTagName("script")[0];s.parentNode.insertBefore(t,s)}}(window,document);
  rdt('init','a2_xxxxxxxxxxxx');
  rdt('track','PageVisit');
</script>
<!-- End Reddit Pixel -->

Step 2: Install the Pixel in SuperFunnel

Add the base code using Custom Code. Install it globally so the Pixel loads on every page and quiz.

Step 3: Verify the Pixel is firing

Reddit Pixel events: standard vs. custom

The Reddit Pixel recognizes a set of standard events that map to reporting and optimization in Reddit Ads Manager. Custom events are any other name you choose.

Fire a standard event with a single call:

rdt('track', 'Lead');

Add parameters for revenue reporting, for example on an order confirmation page:

rdt('track', 'Purchase', { currency: 'USD', value: 49.99, transactionId: 'order_12345' });

Fire a custom event by setting the event name to Custom and giving it a customEventName that does not match a standard event:

rdt('track', 'Custom', { customEventName: 'demo_booked' });

The important thing to understand: SuperFunnel fires its own events, superfunnel-form-submission when a visitor reaches the Final Step, and the broader superfunnel-conversion for any conversion. Neither is automatically a Reddit Lead event, so Reddit will not count it until you translate it. For the difference between the two, see Default conversion events.

The cleanest way to translate a SuperFunnel form submission into a Reddit Lead event is through Google Tag Manager: create a Custom Event trigger on superfunnel-form-submission, then fire a Custom HTML tag that calls rdt('track', 'Lead').

Firing your own on-page events

For interactions other than form submission, like a CTA click or a mid-quiz email capture, fire your own event with SuperFunnel's JavaScript API and forward it to Reddit:

window.sf.reportEvent("cta-click");
rdt('track', 'Custom', { customEventName: 'cta_click' });

See Online Event Tracking for the full event API, including the sf:step-change hook.

Troubleshooting

• Pixel not detected — refresh the page; confirm the base code is enabled in Custom Code and set to Header.
• rdt is not defined — a tag tried to fire before the base code loaded. Make sure the base code is installed globally and in the header.
• Events overcounted — the Pixel is installed in more than one place, so every event fires twice. Keep a single source. See Debugging Events.
• Events fire on the wrong step — SuperFunnel's form-submission event fires at the final step. If your real conversion happens earlier, fire a custom event at that point instead, see Online Event Tracking.
