Why 80% of AI Traffic Bounces Off Your Website | Anda Gansca, Knotch | Cannes Lions 2026

Anda Gansca of Knotch sits down at Cannes Lions 2026 to explain the rise of the "AI-native consumer"—and why the open web needs to reinvent itself to survive. She breaks down the "conversational web": a new era where websites stop being static billboards and start responding dynamically to what each visitor actually wants. Anda shares why over 80% of consumers arriving from LLMs bounce and never return, how Knotch's ACE engine serves both humans (immersive experiences) and agents (code), and the results so far—including a 20% drop in bounce rate and a 5x lift in engagement for Google. She also makes a provocative case that over-optimizing for AI agents (GEO/AEO) is actually hurting human conversion, and why the real challenge is measurement, the marketing org chart, and the leaky funnel. In this conversation, she covers: 00:00 — The birth of the AI-native consumer 00:46 — What is the "conversational web" and why it matters 01:37 — Why 80%+ of LLM-referred traffic bounces 02:20 — How ACE personalizes for both humans and AI agents 03:37 — The results: Google's bounce down 20%, engagement up 5x, conversion up 3x 04:47 — "Everything's changed and nothing's changed": GEO and AEO in perspective 05:34 — How over-optimizing for agents hurts the human experience 06:40 — Why LLM visibility doesn't yet equal business outcomes 07:19 — Putting personalization in the hands of the consumer 08:46 — A Gen Z take: have you "earned the right" to use AI content? 09:58 — The right metrics—and why the org chart is the real problem 11:59 — Why few large companies have truly embraced AI yet 12:27 — Escaping "pilot purgatory" and who wins in two years 13:29 — Her message to CMOs: AI is powerful, but it's still just another channel A key takeaway: AI has fundamentally changed us as consumers, so marketing has to change too—but it remains multi-channel. The brands that win won't try to game LLMs with 100 more blog posts; they'll do great, integrated marketing that follows the real customer journey.
