Reddit ads conversion tracking connects your advertising spend to actual business outcomes. Without it, you're spending money without knowing what's working. With proper tracking, you can measure ROI, optimize campaigns, and scale what converts.
This guide walks through complete conversion tracking setup—from pixel installation to attribution configuration.
Conversion tracking enables:
Reddit reports that advertisers using conversion tracking see significantly better campaign performance because the algorithm has feedback signals to optimize against.
Reddit's conversion tracking system has three main components:
JavaScript code installed on your website that fires when users visit pages and complete actions. The pixel captures:
Definitions in Reddit Ads Manager that specify which pixel events count as conversions for optimization and reporting.
Rules determining how conversions are credited to ad interactions (click-through, view-through, attribution windows).
Before tracking conversions, install the base pixel on all website pages:
<head> sectionSee our detailed Reddit Pixel setup guide for step-by-step installation instructions.
Add event tracking code where conversions occur:
For lead generation:
<script>
rdt('track', 'Lead');
</script>
Fire this on thank-you pages after form submissions.
For e-commerce purchases:
<script>
rdt('track', 'Purchase', {
value: 149.00,
currency: 'USD',
transactionId: 'ORDER-12345'
});
</script>
Fire this on order confirmation pages.
For sign-ups:
<script>
rdt('track', 'SignUp');
</script>
Fire this after account creation confirmation.
In Reddit Ads Manager:
When creating or editing campaigns:
Reddit's algorithm will now optimize delivery toward users likely to convert.
Tracks conversions that occur after ad clicks. Standard windows:
Longer windows capture more conversions but may include less directly-attributed actions.
Tracks conversions from users who saw (but didn't click) your ad. Standard windows:
View-through attribution is controversial—use shorter windows for conservative measurement.
Short sales cycles (e-commerce, impulse):
Medium cycles (considered purchases):
Long cycles (B2B, high-value):
B2B advertisers frequently undercount conversions using short windows. Reddit research suggests extending to 30 days captures the full impact on B2B purchase decisions.
Prevent counting the same conversion multiple times:
Beyond primary conversions, track engagement signals:
Micro-conversions provide optimization signals before primary conversions accumulate.
Create separate conversion actions for different outcomes:
Segmentation enables more precise optimization and reporting.
Regularly verify conversion tracking accuracy:
Check:
Causes:
Solutions:
Reddit may show conversion data with 24-48 hour delays. This is normal for:
Don't make optimization decisions based on same-day conversion data.
Server-side tracking that complements the pixel:
Implement CAPI for high-value conversion tracking where accuracy is critical.
Pass conversion values to optimize for revenue, not just conversion volume:
rdt('track', 'Purchase', {
value: orderTotal,
currency: 'USD'
});
Reddit's algorithm can then optimize toward higher-value conversions.
For B2B and high-consideration purchases where conversions happen offline (phone calls, in-store, sales meetings), use offline conversion uploads to connect ad exposure to eventual purchase.
For more on measurement, see our guides on Reddit Ads attribution and Reddit Ads reporting.
Accuracy depends on implementation quality, attribution settings, and user behavior (ad blockers, cross-device). Pixel-based tracking typically captures 60-80% of actual conversions. Adding Conversion API improves accuracy. Always compare to backend data for calibration.
Not directly through the pixel. Use call tracking software that integrates with Reddit's offline conversion upload, or track calls as micro-conversions by firing events when phone number links are clicked.
Reddit recommends 15-20 conversions per week per ad group for effective optimization. Below this threshold, consider optimizing toward higher-volume events (clicks, page views) or consolidating ad groups to accumulate more conversion data.
