About

About Me

I run controlled experiments on how AI systems discover, cite, and recommend websites.

My work sits between research and implementation. I build real sites, observe model behavior, and publish what survives contact with the live web.

I care less about abstract AI commentary than about the mechanics that change outcomes in practice: structure, visibility, discoverability, and the conditions that make a website usable inside AI systems.

Organization

Where the work lives.

This personal site is one part of the work. The experiments, frameworks, and implementation lens extend into Minnesota.AI and AIFDS.org as well.

    Writing, theory, and field notes

    This site is the public record of the thinking: foundation definitions, plain-language explanations, and the ideas that connect live experiments into a coherent body of work.

    The field lab

    Through Minnesota.AI, I work on applied research, live systems, and experiments built to measure what AI systems actually do in practice.

    The open framework

    AIFDS.org is where the framework side of the work lives: standards, schema direction, and the system design layer behind machine-readable websites.

Published findings

The latest research on the site documents how a brand-new domain earned ChatGPT citations in just over a month, and what that reveals about structure, token cost, and completion paths.

Approach

What guides the work.

The goal is not to speculate about AI from a distance. It is to test how models behave around real websites, real constraints, and real user journeys.

Operator lens

I approach AI through production behavior. What matters is what changes outcomes when a real user, a real website, and a real model meet.

Controlled experiments

I prefer live tests over recycled theory. The point is to publish evidence, not to repeat assumptions that collapse under real conditions.

Plain language

A young field needs clear foundations. I write to make complex model behavior legible enough for founders, operators, and technical teams to act on it.

Focus

What this site covers.

Most of the work here is organized around three foundations that explain how websites become usable, trustworthy, and recommendable inside AI systems.

Foundation

LLM Structure

The machine-readable architecture that makes a website legible to models in the first place.

Foundation

LLM Visibility

The conditions that let an AI system access, parse, understand, and verify what a website is saying.

Explore LLM Visibility

Foundation

LLM Discoverability

The recommendation layer: the moment a model decides a website is the right destination for a user ready to act.
