The partnership is designed to offer advertisers more robust brand-safety assurances, a critical requirement for scaling platform revenue. It reflects a broader effort to standardize measurement practices as the company captures an increasing share of digital ad spend.

Reddit reported $625 million in quarterly ad revenue, a 74% increase year-over-year, while high-intent shopping conversations rose 40% compared to the prior year.
