Perplexity's founders joining the nine-figure club in 2025, as reported by Natallie Rocha in The New York Times, marks a significant milestone in the AI industry's rapid growth. This development is a testament to the immense investment and interest in AI startups, particularly those focused on natural language processing and machine learning. For website owners, this news means that AI-powered tools and platforms, such as those developed by Perplexity and Figure AI, will likely become more prevalent and sophisticated. As a result, website owners can expect to see increased AI bot traffic on their sites, which may require adjustments to their content policies and llms.txt files to ensure they are properly managing and tracking AI-generated content. To prepare for this shift, website owners can take several actionable steps: (1) review and update their llms.txt files to include specific directives for AI bots, (2) monitor their website's traffic and analytics to identify and respond to AI-generated content, and (3) consider implementing AI-detection tools to help manage and filter AI bot traffic, ensuring that their websites remain compliant with evolving AI content policies.
