Install Reddit Ads Pixel with Google Tag Manager

The Reddit pixel is a snippet of JavaScript that tracks visitor behaviour on your website. It sends data back to Reddit Ads so you can measure conversions (purchases, sign-ups, leads), build retargeting audiences from people who visited your site, and optimise campaigns toward specific events. Without it, Reddit Ads cannot report on what happens after a click.

Log in to Reddit Ads, then go to Events Manager in the left-hand navigation. Select the Google Tag Manager installation option and your Pixel ID will be displayed — it starts with a letter followed by numbers (e.g. a2abc1234). Copy this ID to paste into GTM.

Yes. The pixel is tied to your Reddit Ads account, so you need to create an account first at ads.reddit.com. Once your account is active, the pixel is automatically generated and available in Events Manager — you don't need to be running any active campaigns to access it.

Use GTM Preview mode before publishing — visit your website while in Preview mode and confirm the Reddit Pixel tag fires on the page load event. You can also install the Reddit Pixel Helper Chrome extension, which shows a green tick when the pixel is detected on a page. Within Reddit Ads, Events Manager will show Active status once it receives its first signal.

GTM is strongly recommended. It lets you add, update, or remove the pixel without needing developer access to your site's code. You can also fire conversion events and retargeting triggers from the same container. Direct code installation works but every change requires a code deployment — GTM gives you far more flexibility and speed.

Yes. Once the base pixel is installed on all pages, you can create additional GTM tags that fire the Reddit pixel with a specific event type (e.g. Purchase, Lead, AddToCart) triggered only on relevant pages or actions — such as a thank-you page or a button click. This gives Reddit Ads the conversion data needed to optimise your campaigns and measure ROAS accurately.
