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

Why It Matters

Agent‑led discovery reshapes how consumers find products, making AI‑optimized brand visibility a critical competitive advantage.

Key Takeaways

• Agents replace humans as primary internet searchers for consumers.
• Agentic search demands content optimized for AI, not just human SEO.
• Different LLMs prioritize distinct data sources, affecting brand visibility.
• Marketers must make brand information legible and interoperable for agents.
• High‑consideration products see greatest gains from agent‑led discovery.

Summary

The conversation centers on the emergence of "agent‑led growth," where large language model agents like ChatGPT, Gemini, and Claude have become the new front‑door to the internet. Profound’s James Cadwallader argues that marketers who ignore these agents are effectively invisible, and that the platform helps brands become discoverable across the AI‑driven landscape.

Cadwallader explains that agents crawl the web far beyond the traditional top‑four blue‑link results, pulling from the long tail of content. This shifts the goal from human‑focused SEO to creating data that agents can ingest and cite. He also highlights how each LLM leans on different sources—Gemini favors YouTube, ChatGPT leans on Reddit and LinkedIn, while Claude increasingly draws from real‑time web data—making cross‑model monitoring essential.

Illustrative anecdotes include a single query about a shower head that summoned 65 distinct web pages, and a New York Times experiment where readers preferred AI‑written articles. Cadwallader notes that high‑consideration purchases, such as electronics or automobiles, benefit most from this deep‑research capability, and that brands must ensure their information is legible, interoperable, and free of manipulation for agents.

The implication for marketers is clear: content strategies must evolve to serve super‑intelligent agents, requiring scalable, high‑quality AI‑generated assets, platform‑specific optimization, and continuous insight into how each model cites brand data. Companies that master agent legibility will capture the next wave of discovery and conversion.

Original Description

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.
