Who is Jason Hennessey

What GEO / AEO practitioners can learn from Jason Hennessey
- **Crawlability & parsing first**: many AI crawlers render worse than Googlebot, so server-side rendering, clean HTML and a clear heading hierarchy decide inclusion more than flashy JS. - **Structure is signal**: semantic markup and explicit entities/facts make it easier for retrieval systems to lift your passage — the heart of relevance engineering. - **Validate with experiments, not guesses**: treat every change as a testable hypothesis, judged by before/after citation and mention rates.
**GEOly angle**: A go-to voice on local and service-brand visibility, directly relevant to how local businesses earn trust and reputation in AI search.
What it means for brands going global
For brands going global, the first gap is usually not creative — it is the technical foundation: make sure major AI crawlers can access you, that product and content pages carry stable structured data, and that key facts are readable as plain text. Only on that foundation can content and brand signals get cited.
