Who is Martin Splitt
Google Search Relations developer advocate in Zurich and one of the most trusted voices on rendering, JavaScript, and how crawlers actually see a page — increasingly relevant as many AI crawlers render far less than Googlebot.
What these experts share: they treat "can the machine crawl and correctly parse your content" as the first-principles question of GEO — and they answer it with experiments and data, not folklore. Their recurring focus areas include: Google Search, rendering, JavaScript SEO.
What GEO / AEO practitioners can learn from Martin Splitt
- **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**: Guide: AI bots, rendering limits, and accessible content.
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.
