From SEO to Agent-Led Growth: Profound's James Cadwallader

Profound CEO James Cadwallader argues AI agents have replaced the human consumer as the primary audience for marketing content, requiring a total rethink of SEO and content strategy.

• Profound serves ~12% of the Fortune 500; Cadwallader calls agent-led marketing a shift from “nice to have” to “must have.”
• ChatGPT used 65 web pages to answer a shower head query — agents consume orders of magnitude more of the internet than humans do.
• Gemini leans heavily on YouTube; ChatGPT pulls from Reddit (B2C) and LinkedIn (B2B); Claude historically relied more on pre-trained weights but is now using the web more after a recent classifier update.
• Self-serving comparative listicles (e.g., ranking yourself #1 vs. weaker competitors) still work because models take the path of least resistance rather than reasoning from first principles.
• Dead internet theory: Cadwallader considers it plausible within three years that human browsing largely ceases, collapsing ad-funded publisher economics and removing incentives to create original content.
• AI advertising will be the most effective in history — system-prompt-style campaigns targeting users by demographic and moment of peak intent, with hyper-personalized language.
• The new marketing imperative is giving a superintelligent agent original insight it cannot find anywhere else, not gaming rankings or flooding the web with AI-generated slop.
