James Cadwallader, co-founder and CEO of Profound, argues that marketing is undergoing its biggest platform shift ever: the consumer is no longer a human clicking blue links but an AI agent crawling the web on their behalf. He explains that agents like ChatGPT, Gemini, and Claude use the long tail of the internet far more broadly than humans do—citing an example where ChatGPT used 65 webpages to answer a showerhead question. The implications for content strategy are significant: marketers must build content designed to be discovered and consumed by agents, not humans, and must provide original insight that a model trained on the entire internet doesn't already know.
Cadwallader also raises the possibility of a "dead internet" within three years, where the economic incentives to publish content collapse if humans stop visiting webpages. He predicts AI labs will vertically integrate with social media networks to maintain access to human-generated data. On advertising, he envisions a future where ad campaigns are delivered as system prompts, and notes that in B2B contexts, agents are already steering purchase decisions in ways that make traditional advertising less relevant.
ChatGPT Used 65 Pages for a Showerheadstory
Cadwallader used ChatGPT to find a showerhead for his NYC apartment and it referenced 65 different webpages to answer the question, illustrating how much broader an agent's search is compared to a human's.
Each AI Platform Has Its Own Source Biasinsight
Gemini leans heavily on YouTube content, ChatGPT pulls from Reddit for consumer and LinkedIn for B2B, and Claude has recently become more sensitive to real-time web information.
Humans Are a Fleshy API to Realityinsight
Cadwallader argues that humans are the interface between reality and the internet, and marketers must provide original insight that a model trained on all existing data cannot already know.
Self-Serving Listicles Still Work on AI Modelsstrategy
Creating comparative listicles that place your brand at the top and exclude real competitors still works because models prefer content that has already done the comparison work rather than reasoning from first principles.
Dead Internet Could Arrive Within Three Yearsinsight
If humans stop visiting webpages, advertising revenue collapses, publishers lose incentive to create content, and the information ecosystem that AI relies on begins to break down.
The Future Ad Unit Is a System Promptstrategy
Cadwallader envisions ad campaigns delivered as system prompts where you specify target audience, context triggers, and brand knowledge, and the model delivers the ad conversationally at the moment of highest responsiveness.
Real-Time Battle Cards From Sales Transcriptsstrategy
Profound built an internal agent that ingests all Gong sales call transcripts, buckets objections into themes, and generates battle cards for the sales team daily—something that previously took a human a quarter.
James Cadwallader, co-founder and CEO of Profound, makes the case that we are living through the biggest platform shift in marketing history. The front door of the internet hasn't changed, but the visitor walking through it has. Where consumers once clicked blue links, AI agents now crawl the web on their behalf, synthesizing answers and steering purchase decisions at scale. James explains why Gemini, ChatGPT, and Claude all recommend brands differently, why mapping AI visibility onto traditional SEO is the wrong instinct, and why the real imperative is to equip a superintelligent agent with original insight it couldn't find anywhere else. He also digs into the dead internet theory – the possibility that human browsing could largely cease within three years – how AI advertising may become the most effective form the world has ever seen, and why agent-led marketing isn't just automation of the old work, but an entirely new capability.
