How Reddit MAX campaigns work
MAX automates targeting, creative rotation, placements and budget for Traffic and Conversions. This guide covers the controls and the evidence.
Reddit MAX campaigns launched in beta in January 2026 for selected Traffic and Conversion advertisers, automating targeting, creative rotation, placements and budget allocation. Alpha testing across 600 plus advertisers and 17 split tests reported 17 per cent lower CPA with 27 per cent more conversions.
What you control#
Objective, budget, audience suggestions (communities, keywords, interests, custom inclusions) and hard constraints (locations, exclusions, brand safety). Suggestions steer; constraints bind. The most useful input is signal: Pixel plus CAPI feeding conversions the model can learn from. Product page: Reddit MAX page.
Community Intelligence#
MAX draws on first-party signals plus models over billions of posts and comments, fused with creative, landing-page and performance data. Top Audience Personas cluster engaged users and show current interests: the clearest conversation-pattern intelligence inside paid optimisation to date.

The evidence, honestly#
Seventeen per cent lower CPA and 27 per cent more conversions is Reddit internal testing across 17 split tests, June to August 2025: promising, selected, unaudited. Brooks Running ran MAX untouched 21 days to 37 per cent lower CPC with 27 per cent more clicks. Treat both as reasons to test, not promises to budget. Launch source: Reddit MAX beta.
Baseline testing#
Run MAX beside a manual baseline on the same objective with comparable budgets for 21 days minimum, then compare CPA, volume and quality. Keep the manual live until MAX beats it twice; autopilot with no instruments is hope. Automated revenue reportedly grew 150 per cent quarter on quarter in Q2 2026, so the test is worth running. Deck: MAX deck.
Availability status#
Rollout is ongoing: Reddit own page notes some advertisers lack access while September 2026 trade press reports general availability. App campaigns joined beta in May 2026 with 15 per cent lower CPA reported. Check Ads Manager for your account rather than trusting either headline. Trade note: Social Media Today.
Putting MAX testing into practice#
Launch the MAX-versus-manual protocol this month on the strongest conversion campaign: matched budgets, 21-day minimum, CPA plus volume plus quality scorecards. Keep manual live until MAX wins twice, then expand to the next campaign. Protocols beat enthusiasm.
Feed MAX quarterly with fresh creative and reviewed constraints; automation degrades on stale inputs like everything else. Maintenance: fatigue and refresh and personas.
