As Reddit builds out its advertising stack and attracts more advertisers to its now-public site, the social news platform is continuing to expand its brand suitability and measurement offerings as it forges a new partnership with ad-verification company Zefr. 

Over the past several years, Reddit has grown into a leading consumer discovery platform and destination for advertisers.

After going public in March 2024, the company focused on developing more ad tools that paired artificial intelligence (AI) with the platform’s billions of native shopping conversations.   

This includes Dynamic Product Ads, which are designed to serve the most relevant products to people based on their on-app activity.

Along with a variety of tools, features, and merchant platform integrations, Reddit recently expanded both its chat-based Conversation Ads and AI-powered Max campaigns, while onboarding AI ad platform Smartly. 

As Reddit updates and expands its ad offerings, major advertisers as well as small and medium-sized businesses are flocking to the platform.

In May, Reddit boosted its ad revenue by 74% year-over-year, reaching $625 million for the quarter and reporting a 40% year-over-year rise in high-intent shopping conversations on the platform. 

Reddit has added Zefr to its list of previous brand-suitability partnerships -- with Integral Ad Science (IAS) and DoubleVerify -- in an effort to provide advertising partners with a more complete and brand-safe experience.

According to a statement made by Zefr, the company’s technology is designed to help advertisers better align campaigns with suitable conversations taking place on Reddit by providing insights that are intended to inform media quality, suitability, audience strategy and campaign performance.

“The depth and nuance that make these conversations valuable also create an opportunity for advertisers to reach relevant audiences and unlock valuable inventory with greater precision,” Zefr’s announcement reads. 

Reddit’s Senior Director of Global Product Marketing Nishe Modoyan says Reddit's AI-powered technology should help brands account for the nuance of consumer conversations and provide a greater understanding of which communities to target on the website and app.

In addition to Reddit, Zefr currently has partnerships with YouTube, TikTok, Meta, Snapchat and other digital platforms.
