I study why language models cite what they cite.

An editor’s question, treated as a philosopher’s problem.

Machines now decide which sources to trust, millions of times a day, and my field treats that decision as a ranking problem. It is older than ranking. Every tradition that ever formed a canon faced the same question. Which voices speak for the whole, and what earns them the place? Before it was a search metric, authoritative was a word about scripture. Search inherited the question. Language models industrialized it.

I know the question from both ends. I edit machine-written text for a living, and I have spent years earning citations for businesses too small to buy visibility. An e-bike rental on the Outer Banks now comes up when travelers ask an AI assistant where to rent, ahead of fleets many times its size. Their site holds what is true on the ground. Which bike rides on packed sand, when the tide opens the beach at sunrise, which trail fits which town. The machine trusted the business that had touched the reality it described.

This site works out why authority still has to be earned, and what the machines that grant it are recognizing.

What I do

An AI SEO and content editor by trade, I read machine-written text every day and decide what ships. I have worked in SEO and digital content strategy since 2017, nearly eight years of it as a freelance digital strategist for small businesses in finance, healthcare, e-commerce, manufacturing, and the skilled trades. Two and a half of those years I spent as chief marketing officer of an online gaming platform.

What I write about

The epistemology of machine citation. Why a language model treats one source as authoritative and ignores another. My field runs ranking experiments on that question. I read it through source criticism and the long history of how testimony earns trust.

The editor’s chair. Notes from reading machine output every day. What the recurring patterns reveal about language, and what judgment looks like in a job invented in the last five years.

The record

Sweet Rides OBX. The e-bike rental in the story above. I set the site strategy and wrote every word of the copy. The citations followed.

Laser Engraving Pros. The modern face of National Seal Works, a Richmond manufacturer operating since 1891. Organic search was the primary acquisition channel while revenue grew fivefold in two years.

Certifications. Google Analytics. Google Digital Marketing & E-commerce. HubSpot Inbound Marketing. HubSpot SEO.
