Do I need to rewrite pages to be more extractable by LLMs?

Usually, no—you probably don’t need to rewrite all your pages just to make them “LLM-extractable.”

If you mean can an LLM understand and use the content on your pages?, the main things that matter are:

• Clean, text-based HTML: normal headings, paragraphs, lists, tables
• Accessible structure: clear hierarchy, descriptive headings, semantic markup
• Content visible in the DOM: not hidden behind heavy client-side rendering or interactions
• Minimal clutter: avoid burying the useful content under lots of boilerplate
• Stable URLs and crawlable pages: no excessive blocking via robots/noindex if you want them discovered

You likely don’t need to rewrite if:

• Your pages are already mostly HTML text
• Important content is not locked behind JavaScript-only rendering
• Headings and sections are logically organized
• Your pages aren’t mostly images, canvas, or PDFs without text
• The content is not fragmented across tabs/accordions that don’t render server-side

You might want to improve pages if:

• They’re mostly client-rendered and content appears only after JS runs
• Key text is embedded in images or complex widgets
• You use lots of generic headings like “Overview” everywhere with little context
• The useful content is buried in nav, ads, popups, or repeated boilerplate
• Tables/lists are visually formatted but not semantically structured

Good practical rule

If a human can open the page and quickly see:

1. what the page is about,
2. the main sections,
3. the key facts,

then an LLM usually has a decent chance of extracting it.

If you want to optimize for both humans and LLMs

Focus on:

• Semantic HTML
• Clear headings
• Concise summaries
• Accessible content structure
• Server-side rendering or pre-rendering for critical content

If you want, I can give you a checklist for making pages LLM-friendly without a full redesign.
