TIME began experimenting with a new advertising model designed for AI agents rather than human readers. This method involves creating simplified, machine-readable Markdown versions of webpages that include sponsored content in a question-and-answer format. Early participants in this experiment included Ally Bank and the Project Management Institute.

In response to these experiments, Perplexity blocked advertising placed within these AI-readable Markdown files from influencing its search index. Perplexity characterized the practice as “deceptive advertising,” noting that the sponsored material is not visible to human readers on standard HTML webpages. The company warned that publishers using such methods risk a downgrade in its search index.
