About Cay Horstmann's Home Page
from our crawl and measurement
"[email protected] | PGP Key I grew up in Northern Germany and attended the Christian-Albrechts-Universität in Kiel, a harbor town at the Baltic sea." That is how Cay Horstmann's Home Page introduces itself. To AI engines like ChatGPT and Perplexity it is partially visible, scoring 6.7 out of 10, readable in places, missing in others.
The site gets some of it right: it has a readable heading structure. What holds it back is what is absent, including structured data describing the business, an llms.txt file, a sitemap.
AI crawlers have visited the site 4 times in our tracking, so the engines are already looking.
