Domain knowledge, made visible.
Deep Domain helps specialist UK retailers and local businesses make their real expertise easier for search engines and AI answer tools to find, understand and cite.
Who is behind Deep Domain?
Deep Domain is run by Matt Billing. Matt’s background is in infrastructure and systems engineering, where useful work depends on evidence, repeatability, clear failure modes and careful change control. He applies the same discipline to AI visibility.
The work combines technical site retrieval checks, structured content, entity consistency, competitor and source analysis, and repeatable testing across web-grounded AI providers. The aim is not to manufacture expertise. It is to extract the expertise already inside a business and publish it in forms that customers, search engines and AI systems can use.
What has been built already
Measured audits
Buyer-style questions tested repeatedly across OpenAI and Anthropic, with models, timestamps, sources and competitor mentions retained.
Retrieval checks
A live-site checker that tests initial HTML, index signals, metadata, schema, canonical facts, robots rules and sitemaps.
Specialist content systems
Reviewed pipelines for product descriptions, FAQs and knowledge-base content in specialist retail environments.
Client-ready reporting
Dated PDF findings, technical appendices, quality assurance and remeasurement plans built around evidence rather than tool scores.
Working principles
Talk through your visibility gap.
