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).
Highlights a widespread publisher strategy (buying paid traffic) and the ongoing risk of MFA-related blacklisting that affects monetization, buyer trust, and programmatic supply quality across the open web.

Key Takeaways & Evidence Grounding
- Publishers are increasingly using paid traffic to replace declining referral and search traffic.
- The 2023 ANA report on made-for-advertising (MFA) sites prompted agencies to cut back on arbitrage inventory, affecting publisher tactics since then.
- Vendors and DSPs use MFA blocklists and ambiguous thresholds that can flag publishers buying paid traffic, risking advertiser blocks.
- Industry sources cited include Chris Kane (founder, Jounce Media), Justin Barton (SVP of digital strategy and partnerships, Black Enterprise), Elli Papadaki (SVP of global supply, Onetag), and Alessandro De Zanche (publisher consultant, ADZ Strategies).

MFA Ad Spend Rises; AI Slop May Be Factor
The ANA’s Q1 programmatic benchmark report (released May) found that the share of ANA members' ad spend going to made-for-advertising (MFA) sites rose from 0.6% in Q4 2025 to 1.1% in Q1 2026 — the first increase since 2023. The report highlights that lower-performing advertisers allocate a larger share to MFA (2.1%) versus top performers (0.9%). The ANA and industry experts point to “AI slop” — low-effort, mostly AI-generated content — as an emerging sub-type of low-quality inventory that requires ongoing mitigation. Publishers, SSPs and ad tech vendors (Index Exchange, Nexxen) say they use vetting, human audits, blocklists from vendors like Jounce and DeepSee, and onboarding delays for new sites to limit MFA monetization. Independent studies cited (Ahrefs, Graphite) suggest a rapid increase in AI-generated content online, complicating distinctions between legitimate AI-assisted publishing and spammy content farms.
OAAA Launches Programmatic Center of Excellence for DOOH
AI is pushing advertising back into physical spaces due to declining trust in online content, the rise of AI answer engines that bypass websites, and the growth of agentic AI. Out-of-home (OOH) and digital out-of-home (DOOH) advertising are gaining renewed relevance, with US OOH revenue up 10.7% YoY to $3.16B in Q2 and DOOH up 18.5%, representing nearly 40% of category revenue. To guide this evolution, the OAAA has launched a Programmatic & Automation Center of Excellence led by COO Patrick Dolan, focusing on standardization, workflow automation, agentic AI, reporting/attribution, and omnichannel/retail media integration. The initiative aims to automate both programmatic and static OOH processes, addressing friction points. However, this trend raises concerns about consumer opt-out options and the over-commercialization of public spaces, as noted by Ezra Klein.
Google Antitrust Ruling Spares Ad Stack, Pressures Trade Desk
A federal judge ruled that Google must open up its ad exchange and publisher ad server to more competition but stopped short of forcing a breakup of its adtech stack. The remedies include connecting AdX and DFP to Prebid, requiring equal terms for AdX bids on alternative servers, curbing self-preferencing, and sharing auction data. For The Trade Desk, which has positioned itself as the neutral alternative to Google's walled gardens, this outcome weakens its core pitch: a fairer and more transparent auction reduces the urgency for publishers to seek alternatives like OpenPath. The article also notes that Google's decision to keep third-party cookies has already slowed adoption of alternative IDs like UID2.0. Analysts suggest The Trade Desk's narrative is shifting towards CTV and agentic advertising as the open-web competition with Google evolves.
