LLM readability · Machine readability
LLM-readability is how easily an LLM can parse, segment and extract a piece of content. It relies on explicit headings, standalone sections, stable terminology and high factual density. It is a practitioner term, with no standard.
Standalone definition · 36 words
Which criteria determine it?
Semantic HTML and a clean heading hierarchy, content present in the initial HTML, short sections focused on one subject, tables with headers, explicit entity names and consistent terms. Content hidden behind JavaScript, tabs with no text or undescribed images loses readability.
How do you audit LLM-readability?
View the page source, check that text and links are present, read each section in isolation to judge whether it stands on its own, test extraction with a tool that converts the page to text or Markdown and compare what comes out with what is displayed.
What are the common mistakes?
Vague headings (“Learn more”), pronouns with no referent, scattered definitions, tables as images, FAQs hidden or loaded on the client side and pages that mix several subjects without headings. Each reduces the chance that a passage is extracted cleanly.
