Reddit Ads Retargeting is the practice of serving 📝Reddit Advertising placements to users who have previously interacted with a brand — through website visits, ad engagement, or uploaded customer lists — rather than to cold prospects. 📝Reddit's retargeting capabilities lag Facebook and Google in maturity but have closed significantly since the platform's 2024 IPO, with audience creation and custom audience uploads now matching the basic functionality of incumbent platforms.
The Three Retargeting Surfaces
Website retargeting is the most common path. Brands install the 📝Reddit Conversion Pixel on their site, which tracks visitors and lets advertisers build audiences from page views, custom events, or specific URL patterns. Retargeting audiences need to reach a minimum size before Reddit will serve ads to them.
Customer list retargeting uses uploaded CRM data — email addresses or mobile advertising IDs — hashed and matched against Reddit's user base. Match rates are lower than Facebook's because Reddit users are more likely to use pseudonymous accounts. The trade-off is that the audience reaching match is highly intentional.
Engagement retargeting is Reddit's distinctive offering. Brands can retarget users who upvoted, commented on, or saved their previous ads — a behavior signal that doesn't exist on visual-first platforms. The audience is small but qualified: a user who upvoted your ad is signaling more than a passive impression.
Audiences and Lookalikes
Reddit launched lookalike audiences in the early 2020s and has improved them iteratively since. The platform offers tighter (more similar) and broader (more reach) lookalike variants. Lookalike performance is typically strongest when seeded from converters or high-LTV customer segments, not just any list of past visitors.
Custom audiences combine retargeting sources — for example, people who visited the pricing page in the last 30 days AND match the high-LTV lookalike. This kind of audience layering is where Reddit's ad platform now competes with Facebook's targeting depth.
Where Reddit Retargeting Falls Short
Pixel-based retargeting depends on third-party cookie infrastructure, which continues to degrade across browser privacy changes. 📝Reddit Pre-IPO Privacy Changes reduced the data available for cross-site tracking. Server-side conversion APIs (similar to Facebook's CAPI) are available but require engineering setup that most advertisers haven't completed.
The platform lacks dynamic creative retargeting at parity with Facebook's Dynamic Product Ads — Reddit's DPA exists but feeds primarily from Shopify product catalogs rather than user-specific browse history.
When to Use Retargeting on Reddit
Retargeting works best on Reddit when paired with strong organic presence. A user who has seen your brand discussed positively in a relevant 📝subreddit, then visits your site, then sees a Reddit ad — converts at materially higher rates than cold ad clicks. Without that organic context, retargeting on Reddit performs closer to retargeting on a low-intent platform.
