Jekyll AI readiness statistics

In November 2026, we could only tell which sites run on Jekyll where our scanner could read the page, so this page covers those sites and says nothing about how many turned our scanner away.

Based on the sites Bot Appétit has scanned. Most of these sites come from lists we scan for research. Not a random sample of the web.

All sites on the State of the Web

How Jekyll sites land

Every page we read gets a score out of 100, the number at the top of its report (how scoring works). Each row is a range of scores. Where too few sites score in the lowest ranges, they are joined into one row.

A platform is only detectable on a page our scanner could read, so these shares are of the Jekyll sites we could read.

What Jekyll sites get right and wrong

Passed more often than on the average site: “Structured data is present” (83%, against 53% of all sites); “Buttons, links and fields have names” (58%, against 37% of all sites); “Author / publisher is clear” (62%, against 47% of all sites). Least often passed: several checks that no Jekyll site we could read passed.

Every check, Jekyll against all sites

Share of sites that pass each check, over the sites the check applies to. The Gap column is the difference in percentage points between the two shares; a dash means not enough sites yet.
