A Fospha report has revealed that cost per purchase improved by 34% for businesses that invested in Reddit, as well as a 257% increase in revenue.
With its online communities now translating to efficient performance levels, B2B businesses are now using social platforms to go beyond brand building and prove direct ROI.
This highlights a shift in customer communities as this stage becomes the first major step in the customer journey, shaping how buyers form their initial understanding and expectations.
Dennis Cardoso, Global Head of Marketing Science at Reddit, argues that meaningful conversations in high-intent communities are now creating long-term returns on ad spend, especially when supported by AI-driven campaign tools.
“The real return isn’t in the click, it’s in the conversation,” he explained.
“Those conversations unlock long-term ROAS, especially when combined with our AI-led Max Campaigns and Reddit’s uniquely high intent communities.”
How Growing Communities Drive Early Engagement and Measurable ROI
In its Q4 2025 results, the community platform reportedly saw 121 million daily active users on its site, with many participating in focused, interest-driven discussions.
As a result, this daily user base has given advertisers better access to large audiences that engage with detailed content and product research, with investment growth aligning to measurable improvements.
As more businesses began investing in the platform, many reported an increase in ROAS despite contributing higher spend, demonstrating strong ROI.
With most of Reddit’s impact occurring before the final conversion, users read explanations, compare products, and form trust within communities, with its influence is only reporting 3% share of revenue credit with a last click attribution model.
When advertisers use attribution methods that capture earlier signals, Reddit’s contribution appears significantly higher, as these communities play an important role in shaping the customer journey.
AI-Powered Campaigns for Measurable ROI
Reddit are also now using AI to improve ad performance and efficiency in ways that help advertisers prove return on investment.
Having introduced Max Campaigns toward the start of the year, this AI-powered campaign supports efficient spend and helps convert conversations into measurable long-term value. Using machine learning to analyze signals from Reddit’s community behavior, businesses can predict the value of every ad impression.
