Content
Is the content legible to a no-JS agent — server rendering, a Markdown twin, JSON-LD, declared language and encoding.
-
page-parsed
Server-side rendering
The meaningful content is present in the raw HTTP response, not only after JavaScript runs.
-
page-parsed
Markdown twin
A <link rel="alternate" type="text/markdown"> advertising a low-token Markdown copy of the page.
-
page-parsed
JSON-LD structured data
Parseable schema.org JSON-LD with an @context, an @type, ISO-8601 dates, and any Google-required props.
-
page-parsed
Language & encoding
A valid BCP 47 <html lang> and an early UTF-8 <meta charset> so agents read the text correctly.
