About Greil Marcus / Letter in the Ether
from our crawl and measurement
"Everyday culture and found objects. Click to read Greil Marcus / Letter in the Ether, a Substack publication with tens of thousands of subscribers." That is how Greil Marcus / Letter in the Ether introduces itself. Its AI visibility score is 6.7 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.
