How fan-out behavior has evolved over time.


Real-world data and comparisons between ChatGPT and Google.

How to measure AI search: The 5 stages of SEO grief

San Diego, September 2026

In this talk, Rob will walk through the "5 stages of SEO grief" that marketers are experiencing as AI transforms search — from denial that AI Overviews are a passing fad, through anger at plummeting click-through rates and plagiarism lawsuits, bargaining with listicles and content "chunking," depression over whether SEO is finally dead, and finally acceptance of a new reality.

He'll share hard data on how AI Overviews have cut organic CTR, explore why traditional SEO tactics like llms.txt aren't the answer, and show how brand mentions across the web (not just backlinks) are becoming the strongest predictor of AI visibility.

Rob will close with practical guidance on how to actually measure AI search performance — including where to find the prompts to track, how to monitor AI referral traffic and bot activity, and which metrics (brand mentions, AI citations, branded traffic) matter for the future, replacing outdated ones like impressions, rankings, and CTR.

AI doesn’t care about your org chart: Why authority (not channels) wins in GEO

San Diego, September 2026

Most GEO conversations still center on prompts, citations, visibility tracking and AI recommendations.

What gets less attention is where influence is actually being built, and why some brands are consistently surfaced while others remain invisible.


This session is designed for marketers, SEOs and brand leaders trying to understand how visibility is earned in AI-powered search.


It explores three areas shaping the future of GEO:
• Why visibility is won beyond the website
• Which citations carry real influence
• Why many organizations are not structured to build authority at scale


Using citation analysis across multiple industries, the talk will show how authority is shaped by publishers, communities, review platforms, creators, affiliates and other trusted sources. It will also look at why the strongest signals vary by category, and how fragmented teams, budgets and KPIs can limit GEO performance.


Attendees will leave with a clearer view of the authority ecosystems that matter in their industry, plus a practical way to align SEO, PR, affiliates, community and social activity around the signals that influence AI recommendations.
