The Opportunity: Reddit is not just another social media platform. It's sprawling collection of internet's most passionate and engaged niche communities. For advertisers who know how to navigate it, Reddit offers direct line to highly specific, motivated audiences that are unreachable anywhere else.
The Challenge: However, tracking performance on Reddit requires different mindset. Its native tracking tool, the Reddit Pixel, is essential for running campaigns, but it has reputation for being temperamental. Relying on it as your single source of truth is a mistake.
This Guide: Provides complete, step-by-step walkthrough for installing Reddit Pixel and configuring conversion events. But more importantly, it gives you realistic framework for measuring success on platform. We show you how to use pixel for its strengths (retargeting and optimization signals) while building separate, unshakeable "ground truth" using UTM parameters and first-party data to measure actual ROI.
Reddit Pixel is snippet of JavaScript you place on your website.
It acts as communication bridge between your site and your Reddit Ads dashboard.
1. Conversion Tracking
Report when user who clicked your Reddit ad completes key action
Purchase or lead submission
2. Retargeting
Build audiences of users who have visited your site
Serve them follow-up ads on Reddit
3. Audience Expansion
While it's necessary for all three, its true, reliable strength lies in retargeting.
For conversion tracking, it's best viewed as directional signal for Reddit's algorithm, not as accurate, final report for your business.
All browser-side pixels are fighting losing battle against data loss from ad blockers and privacy settings.
But Reddit's pixel often presents additional layer of challenge, with many experienced advertisers reporting inconsistencies.
This means "conversions" number in your Reddit Ads dashboard is often heavily estimated guess.
Examples:
Might see 10 conversions reported when you actually got 15
Might see 5 when you actually got 2
Making budget decisions based on this shaky data is how you kill potentially profitable campaigns.
Solution is not to abandon pixel, but to supplement it with system you can trust completely.
Let's get foundational pixel installed. Recommended method is via Google Tag Manager.
Log in to your Reddit Ads account
In top-left menu, click "Dashboard" and select "Events Manager"
In "Pixel Setup" section, you'll see box to "Set Up Reddit Pixel"
You'll be presented with your pixel code
You only need one piece of information from this: your Advertiser ID
It will be labeled as reddit_advertiser_id and will look something like t2_12345ab
Copy this ID
This is most efficient and reliable way to manage your pixel and its associated events.
Log in to your Google Tag Manager account and open your website container
Go to Tags and click New
Name your tag "Reddit - Base Pixel"
Click on Tag Configuration
Search Community Template Gallery for "Reddit Pixel" template and add it to workspace
In Advertiser ID field, paste ID you copied from Reddit Ads
Leave "Event to Fire" field on its default, "PageVisit" (this is base page view tracking)
Click on Triggering box and select All Pages trigger
Save the tag (do not publish yet; we will add conversion events first)
Now you need to tell Reddit about specific actions. Let's set up "Lead" event as example.
In GTM, create another New tag
Name it "Reddit - Conversion - Lead"
For Tag Configuration, select same "Reddit Pixel" template
Paste in your Advertiser ID again
This time, change "Event to Fire" dropdown to "Lead"
Click on Triggering box (you need to create new trigger that fires only on your "thank you" page)
Click + icon to create new trigger
Name it "Page View - Thank You Page"
Choose trigger type "Page View"
Set it to fire on "Some Page Views"
Configure rule to fire when "Page URL" contains "/thank-you" (or whatever uniquely identifies your confirmation page)
Save the trigger
Save the tag
You can now Submit and Publish your GTM container, which now includes base pixel and your new conversion event
Use Reddit Pixel Helper Chrome extension.
Install Reddit Pixel Helper extension
Visit your website
Navigate through conversion flow
Extension icon will light up and show you which events (PageVisit, Lead, etc.) are firing correctly on each page
You've now installed pixel. Reddit's ad system is receiving signals it needs to optimize and retarget.
But you still don't have reliable number for attribution.
This is where you build your own source of truth.
For every single Reddit ad you run, use rigorous and specific UTM structure.
utm_source=reddit
utm_medium=cpc
utm_campaign={{campaign.name}}
utm_content={{ad.name}}
utm_term={{subreddit}}
Use {{subreddit}} dynamic parameter to automatically insert name of subreddit where your ad was shown.
This is critical step.
Platform like DataCops uses unblockable, first-party script.
When user clicks your Reddit ad and lands on your site, DataCops does two things flawlessly:
Captures detailed UTM parameters from URL:
Tracks user's entire journey on site:
From landing page to conversion
Immune to ad blockers
Now, you can ignore shaky numbers in Reddit Ads dashboard.
Instead, you look at your DataCops analytics or your CRM (which DataCops feeds data into) and see undeniable truth:
Example: "We generated 12 leads last week. Source for all 12 was reddit, and utm_term shows they came from r/supplychain and r/logistics subreddits."
This is your ground truth. It's 100% accurate.
You can now confidently:
Calculate true ROI of Reddit campaigns
Decide whether to scale budget
Knowing decision is based on real data, not platform estimates
Purpose:
Enable retargeting
Provide optimization signals to Reddit's algorithm
Build lookalike audiences
Limitation:
Not reliable for attribution
Numbers often inconsistent
View as directional signal only
Purpose:
Know what is actually working
Measure true revenue
Calculate real ROI
Method:
Rigorous UTM parameters on every ad
First-party tracking (DataCops) to capture UTMs
Track complete user journey immune to blockers
Analyze in your own analytics or CRM
Result:
100% accurate ground truth
Confident budget decisions
Precise ROI measurement

Follow installation guide above via GTM
Enable retargeting and platform optimization
Provide directional signals to algorithm
Step 2: Create Rigorous UTM Structure
Every Reddit ad must have complete UTM parameters
Use reddit as source, cpc as medium
Include campaign, content, and subreddit ({{subreddit}})
Step 3: Deploy First-Party Tracking
Implement DataCops for unblockable tracking
Capture UTM parameters from URL
Track complete user journey immune to blockers
Step 4: Analyze Ground Truth Data
Ignore shaky Reddit Ads dashboard numbers
Review first-party analytics or CRM for accurate attribution

The bottom line: Success on Reddit requires two-pronged approach. You must install Reddit Pixel to enable platform's own tools for retargeting and delivery optimization. It is necessary piece of puzzle. But for far more important job of business intelligence (knowing what is actually working and driving revenue) you must have independent source of truth. Disciplined UTM strategy combined with powerful first-party data platform like DataCops provides this truth. It allows you to leverage Reddit's unique communities with confidence that every dollar you spend is measured with absolute precision.
