About Substack
from our crawl and measurement
"They are so old they brush up against the beginning of civilisation, and yet, we are seeing them today in their youthScott Alexander111You made it, you own itYou always own...." That is how Substack introduces itself. Its AI visibility score is 6.8 out of 10: the engines can find it, but they do not have much to hold on to.
The site gets some of it right: it has a sitemap. What holds it back is what is absent, including structured data describing the business, an llms.txt file, a heading structure that lays out what it offers.

What this score means
Your AEO score measures whether AI search engines - ChatGPT, Claude, Perplexity, Gemini - can actually read your site and cite it in answers. Roughly two-thirds of sites are invisible to them. At 6.8/10, Substack has a working base to build on - fixable, and the signals above are where to start.
