AI search platform Perplexity has stopped Time’s markdown ads from affecting its search index. The company warns publishers about deceptive ad tactics. Trust scores and search visibility may be impacted.
Publishers experimenting with new ad formats aimed at AI agents are facing resistance from major AI search platforms. Perplexity has confirmed it is blocking Time’s markdown-based ads, which were designed to be read by AI agents rather than human visitors, from influencing its search index or results.
The move comes shortly after reports that Time began embedding ads in markdown versions of its articles, specifically targeting AI-driven crawlers and assistants. Perplexity stated that it actively works to shield users from what it considers deceptive advertising practices, regardless of whether the ads are sponsored. The company’s chief communications officer, Jesse Dwyer, said publishers using such tactics could see their trust scores downgraded and their content’s visibility reduced in Perplexity’s proprietary search index.
This development highlights growing friction between publishers seeking new monetization channels through AI and platforms prioritizing user trust and content integrity. As AI agents become more common in content discovery and aggregation, the rules around advertising transparency and influence are being tested. Perplexity’s stance signals that platforms may penalize publishers who attempt to manipulate AI-driven search results with non-traditional ad formats.
Other publishers and marketers are also exploring ways to reach AI-powered audiences. For example, some retailers have begun integrating sponsored product placements into their AI assistants, as seen in this report on Kroger’s approach to AI shopping assistants. The evolving landscape suggests that both publishers and platforms are rapidly adapting their strategies as AI becomes a more significant part of the content ecosystem.
