Free UTM Builder for Reddit Ads
Reddit supports 19 dynamic URL macros using double-curly-brace syntax that auto-populate campaign, ad group, and ad-level data at click time. Reddit Ads remains one of the least-covered ad platforms among UTM tooling, despite steadily growing ad spend from performance marketers.

Reddit Ads tracking gotchas to know before you launch
Macros must stay unchanged in your tracking configuration
Reddit's dynamic macros, written as {{CAMPAIGN_NAME}}, {{ADGROUP_ID}}, and similar, need to be entered exactly as documented. Modifying the format or using an unsupported parameter name can break attribution or limit how far you can drill into reporting.
Layer campaign, ad group, and ad IDs onto your existing UTMs
If you already have a working UTM setup, you do not need to replace it. Simply append Reddit's recommended ID parameters, campaign_id, ad_group_id, and ad_id, alongside your existing utm_source and utm_campaign values for more granular reporting.
Reddit's audience skews toward research-heavy, skeptical clicks
Traffic from Reddit often arrives further along in the research process than traffic from other paid social platforms, so utm_campaign values that map to specific subreddits or communities are usually worth the extra tagging effort.
Reddit Ads UTM FAQ
What UTM parameters does Reddit recommend?
A typical setup uses utm_source=reddit, utm_medium=paid, and utm_campaign={{CAMPAIGN_NAME}}, layered with Reddit's own campaign_id, ad_group_id, and ad_id macros for deeper reporting drill-downs.
Do I need to replace my existing UTM setup for Reddit Ads?
No. If your UTM tagging already works, simply append Reddit's recommended ID macros alongside your existing parameters rather than rebuilding the whole tagging structure from scratch.
What utm_medium is standard for Reddit Ads?
paid is a common convention, though some teams use paidsocial to stay consistent with how they tag other paid social platforms.
Should I tag by subreddit or community?
It's often worth it. Reddit traffic behaves differently by community, so encoding the target subreddit into utm_campaign or utm_content lets you see which communities actually convert instead of averaging them together.
