Publishers Weigh Paid Traffic vs. MFA Arbitrage Risk

Publishers are increasingly buying paid traffic to offset declines in referral and organic search traffic, treating paid acquisition as a necessary audience-growth tool. The practice divides the industry: some see paid clicks as legitimate reader-acquisition costs that can lead to subscriptions or direct visits, while others warn it easily slides into made-for-advertising (MFA) arbitrage that agencies and DSPs now block. The 2023 ANA report on MFA prompted a crackdown that still looms over publishers, and vendors that maintain MFA blocklists sometimes keep red-line thresholds ambiguous. Concerns include inflated ad loads on paid visits, poor engagement from paid-heavy audiences, and the risk that generative AI will make low-quality MFA content harder to distinguish from premium sites. Industry voices cited include Chris Kane (Jounce Media), Justin Barton (Black Enterprise), Elli Papadaki (Onetag), and Alessandro De Zanche (ADZ Strategies).
