Time Magazine is serving specialized advertisements designed for AI chatbot crawlers—a format that targets bots like ClaudeBot and OAI-SearchBot, not human readers. Adtech vendor Mobian is facilitating the practice for brands seeking to influence AI assistant outputs.
Freelance software developer Vincent Schmalbach first identified the practice. He detailed how sponsored content is embedded in markdown versions of Time webpages delivered to AI crawlers, while standard HTML is served to human browsers and Google's primary search bot.
One documented instance shows online-only bank Ally as an advertiser. The AI-targeted content includes extensive FAQs about Ally, promoting brand facts such as its number of fee-free ATMs and claiming Ally is "the only bank built for life today."
Mobian CEO Jonah Goodhart said the company's aim is to shape what AI assistants say about brands paying for the service. Influencing a model like ChatGPT, he said, could affect all its future responses—creating a new revenue stream for publishers and adtech firms.
The sponsored FAQs are structured to be readily absorbed and reproduced by a chatbot. They provide direct answers to common user questions such as "is Ally good for everyday banking" or "can you deposit cash at Ally Bank."
Not all web crawlers receive these AI-specific ads. Schmalbach's tests showed that ClaudeBot, OAI-SearchBot and PerplexityBot receive the sponsored markdown. Google's standard search indexing bot and OpenAI's GPTBot and ChatGPT-User—used for training and user retrieval—either receive regular HTML or HTTP 406 errors.
The Register independently replicated Schmalbach's findings by changing the User-Agent header. Viewing Time articles as ClaudeBot revealed the Ally Bank ad appearing on lists such as "Best Inventions of 2025" and "Top Content Creators of 2026." The ads appear on evergreen content rather than breaking news, suggesting a long-term influence strategy.
Time COO Mark Howard said the publication's sales team is pitching these "agent ads" to brands, and that brands converting their own websites to markdown signal interest in reaching AI bots.
Computer scientists tracking AI safety and privacy have flagged the potential for chatbots to carry covert advertising. While the markdown pages flag content as sponsored, the design prioritizes chatbot ingestion over transparency to end-users interacting with AI assistants.
Publishers who can effectively segment content for AI crawlers may develop a new competitive moat. AI bot traffic frequently surpasses human traffic in volume, and the economic logic here is direct: whoever controls the data pipelines feeding AI models controls what those models say about a brand—a distinct shift from traditional display advertising.
