Some of the publishers in your affiliate program are quietly becoming more valuable than their last-click numbers suggest. Others are losing the traffic model that made them commercially viable in the first place. Understanding which is which, and why, is one of the more consequential decisions your program will make in 2026.
AdExchanger’s January 2026 analysis shows publishers have been candid about losing 20%, 30%, and in some cases as much as 90% of their traffic and revenue in 2025, as AI interfaces now answer queries directly and keep users inside those platforms. The revenue model that funded the affiliate content ecosystem is under real pressure, and how your publishers respond to that pressure determines how strategically valuable they become to your program.
Key Takeaways
- According to AdExchanger’s January 2026 analysis, publishers some publishers reported losing 20%, 30%, and in some cases as much as 90% of traffic or revenue in 2025 as zero-click AI search reshaped referral traffic. That pressure threatens the revenue model that funds much of the affiliate content ecosystem.
- Publishers facing traffic loss are responding in two broad ways: restricting AI crawler access or pursuing licensing models. Publishers with licensed, authoritative category content may become more strategically relevant to affiliate programs because their content can be used in AI-generated answers and recommendations.
- Over 500 publishers have signed revenue-share models for AI content use. News Corp, The Guardian, Washington Post, Axios, and The Atlantic have all signed content agreements with major AI platforms.
- Microsoft launched its Publisher Content Marketplace in February 2026, with Business Insider, Conde Nast, and Hearst among the supply partners, creating permissioned infrastructure through which publisher content grounds AI answers.
- The publishers earning AI licensing deals share the same profile that makes them valuable to affiliate programs: demonstrated content authority in specific topic areas.
- Standard last-click attribution understates the value of publishers who have licensed content to AI platforms, because their influence now operates upstream of the click.
What is happening to the publishers your program depends on
Affiliate programs depend on publishers who built their businesses on search-driven traffic. They earned rankings for category queries, monetized the resulting audience through display advertising and affiliate commissions, and used that revenue to fund the kind of structured, comparative, evergreen content that both affiliate programs and AI platforms value most.
That traffic is declining sharply. According to Pew Research Center’s July 2025 study tracking 68,000 real search queries, users clicked on results only 8% of the time when AI summaries appeared in search results, compared to 15% without them. AdExchanger’s January 2026 report also highlights Business Insider saw its organic search traffic fall by 55% between April 2022 and April 2025, and HuffPost lost half of its search referrals over the same period. These are not outliers. They represent a structural redistribution of traffic away from publisher pages and toward AI interfaces that answer queries directly.
The categories most affected are the ones your affiliate program has likely invested most heavily in: informational, comparison, and best-of content. Based on AdExchanger’s analysis, commercial searches featuring AI Overviews grew from 6% of AI Overview appearances in January 2025 to 19% by October 2025, meaning product and category queries are increasingly being answered by AI summaries. The publishers producing that content are losing the traffic that made it economically viable to produce in the first place.
How your publishers are responding, and why it matters for your program
Your publishers are responding to sustained traffic decline in two distinct ways, and those responses lead to very different levels of strategic relevance for your affiliate program.
Some publishers have restricted AI platforms from crawling and using their content, reasoning that content used to generate AI answers that reduce their traffic should not be provided for free. According to AP’s tracking, 79% of top US news sites are now blocking AI training bots, and Cloudflare blocked 416 billion AI scraping requests in the second half of 2025. Research published in December 2025 found that publishers who chose this path saw a 23% decline in total traffic, worsening the problem they were trying to solve.
The second response is licensing. Publishers including News Corp, The Guardian, Washington Post, Axios, and The Atlantic have signed content agreements with major AI platforms that compensate them when their content grounds AI-generated answers. Over 500 publishers have now signed revenue-share models for AI content use. These publishers may now be inside systems that generate AI answers. Where their coverage overlaps with your category, the content informing or cited in those answers may come from a publisher that is simultaneously your affiliate partner and an AI content supplier. Their influence may operate through two channels: the affiliate click your attribution model captures, and upstream AI visibility your attribution model does not yet fully capture.
The new infrastructure connecting publishers and AI platforms
Your publisher relationships are evolving inside a new infrastructure being built to formalize the connection between publisher content and AI-generated answers, and it is worth understanding how it works.
Microsoft launched its Publisher Content Marketplace in February 2026, with Business Insider, Conde Nast, and Hearst among the initial supply partners. In this marketplace, publishers supply licensed content into structured pipelines and receive payment each time their content grounds an AI answer. Publishers set their own terms and meter usage by AI platform. Amazon is building equivalent infrastructure. This shifts the information economy from open-web scraping, where AI platforms used publisher content without compensation, to permissioned, metered access where publishers are paid for each use.
The publishers positioned to negotiate well in this infrastructure are those with demonstrated content authority in specific topic areas and the kind of structured, consumer-oriented content that AI platforms need to ground reliable answers. That profile overlaps substantially with the affiliate publishers that have driven category performance in most programs. The best review sites, comparison platforms, and best-of guide publishers are exactly the content type that AI licensing marketplaces are competing to supply.
An industry initiative called OpenAttribution is working to make this content usage chain fully measurable, mapping five events from content retrieval through to user engagement. Current tools measure at the Cited level, step three of five. As the full chain becomes measurable, the publishers inside that chain will be able to demonstrate their value more concretely.
Why this changes how you should manage your publisher relationships
You do not need to rebuild your affiliate program to respond to this shift. You need to see your existing publisher relationships through a wider lens that accounts for influence operating upstream of the affiliate click.
Standard program management evaluates publishers primarily on last-click return on investment (ROI). That lens captures contribution at the bottom of the funnel and can miss upstream influence when publisher content appears in, informs, or is cited by AI answers before a consumer ever reaches a trackable click. According to Acceleration Partners’ May 2026 AI Strategy Brief, for a travel brand measured using Profound, an AI visibility tracking platform, 28% of active affiliate partners appeared in AI citation data within a single measurement week. For a sports equipment brand, 16 of the top 25 most AI-cited publishers in the category were already active in its affiliate program. These publishers are doing commercial work that last-click models are not capturing.
There are two direct implications for your program. First, some publishers in your program are more strategically important than their affiliate revenue suggests. A publisher contributing significant citation authority in your category may have modest last-click numbers while carrying meaningful upstream influence. That relationship may warrant closer evaluation, targeted briefing, or a test investment beyond what a last-click report alone would recommend. Second, some publishers outside your program are already shaping AI recommendations in your category without any affiliate relationship at all. Citation data consistently reveals publishers appearing in the top cited pages for a brand’s category without being active in that brand’s affiliate program. These can be higher-confidence recruitment targets than publishers identified through search rankings alone, because you know before the conversation starts that their content is already appearing in AI citation data for relevant category queries.

Frequently asked questions
Why are affiliate publishers losing traffic in 2025 and 2026?
AI-powered interfaces including Google AI Overviews, ChatGPT, and Perplexity now answer many queries directly, keeping users inside those platforms. According to Pew Research Center’s July 2025 study tracking 68,000 real search queries, users clicked on results only 8% of the time when AI summaries appeared. Publishers built on high-volume informational and comparison queries, which describes much of the affiliate content ecosystem, are among the most affected.
Which publishers are signing AI content licensing deals?
Publishers including News Corp, The Guardian, Washington Post, Axios, and The Atlantic have signed content agreements with AI platforms such as Microsoft’s PCM since February 2026, includes Business Insider, Conde Nast, and Hearst as supply partners. Over 500 publishers have signed some form of revenue-share model for AI content use.
How do I know if publishers in my affiliate program have AI licensing agreements?
The most direct signals are public licensing announcements, publisher disclosures, marketplace participation, or confirmation from the publisher. AI citation data is a different signal: it shows which publishers appear in AI-generated answers for your brand or category, but it does not prove that a licensing agreement exists. Tools like Profound and the impact.com and Evertune integration can help identify cited publishers and category visibility patterns; those publishers may be licensed content suppliers, crawlable open-web sources, or both depending on the platform and query.
Should I treat AI-licensing publishers differently in my affiliate program?
Publishers that have secured AI licensing deals may influence consumer discovery through more than one path: the affiliate click your attribution model captures and upstream AI visibility it may not. Their last-click numbers may not reflect their full strategic contribution. Brands that map active affiliate publishers against AI citation data can find meaningful overlap, which may reveal publisher relationships that current attribution models undervalue.
What is the Publisher Content Marketplace and how does it affect my affiliate program?
Microsoft’s PCM, is part of an emerging infrastructure layer between publishers and AI platforms. Publishers supply licensed content into structured pipelines and receive payment each time their content grounds an AI-generated answer, shifting from open-web scraping to permissioned, metered access. For your affiliate program, it means that publishers in your network may simultaneously be affiliate partners and AI content suppliers, with both roles contributing to how your brand appears in the recommendations consumers receive.
