Reddit has opened its AI-powered Max campaigns to all advertisers. The product launched with selected advertisers in January and automates targeting, creative selection, placements and budget allocation. Three additions arrive with general availability: API support, a Smartly integration and asset groups.
What Max campaigns do
Max campaigns are Reddit's automated campaign type. Advertisers supply goals, creative and budget; Reddit's system decides targeting, creative combinations, placements and how budget is allocated. It sits in the same family as Google's Performance Max and Meta's Advantage+ campaigns.
Reddit's pitch is the audience data underneath. Targeting draws on each user's interests and engagement actions, which Reddit argues makes it more accurate. Because interests on Reddit are expressed openly at the community level, the claim has some grounding.
The three new features
- API support: the Reddit Ads API now supports Max campaigns, so advertisers can create and manage them through third-party tools.
- Smartly integration: users of the Smartly creative and campaign automation platform can build Max campaigns from inside Smartly.
- Asset groups: multiple sets of creative can live in a single Max campaign. Reddit's example splits groups by product line or use case, such as running shoes, training apparel and fitness accessories, each with its own headlines, media and destination URL. Each group reports separately, so advertisers can see which products and messages drive performance.
Beta results
Reddit says advertisers using Max campaigns during beta saw 17% lower cost per acquisition and more than 27% additional conversions on average. These are platform-reported figures, and Reddit did not publish the comparison baseline.
What to watch
The barrier to entry drops for brands that wanted Reddit but hesitated because they did not know the platform. Picking subreddits and matching creative to community tone is partly handled by the system now.
The usual trade-offs of automated campaigns remain. Visibility into where and how creative served is limited, and on a platform where a mismatched tone earns visible pushback, creative review matters more, not less. Asset groups are the built-in answer: split by product line from the start so you can isolate which message works for which product rather than reading one blended result.
