Before a language model reasons over a webpage, many retrieval pipelines strip it down to markdown, collapsing styling and layout into headings, paragraphs, and lists. A page built with visually-driven but semantically flat HTML, decorative divs standing in for headings, content ordered for a designer's eye rather than a logical hierarchy, converts into a jumbled wall of text that loses the very structure a model relies on to identify what matters. A page built with proper heading hierarchy, one clear H1, nested H2s and H3s that mirror the actual topic tree, and content ordered so the most important facts appear first, converts cleanly, and that clean conversion is what the model actually reads. This is why an llms.txt briefing paired with genuinely well-structured source HTML outperforms either alone: the briefing states the facts explicitly, and the underlying markdown conversion confirms and reinforces them in the same clean structure, which is exactly the redundancy a model rewards with accurate answers.

Both. Markdown conversion is sequential, so a model reading top to bottom weighs earlier content more heavily in short-context retrieval; burying your core offering below unrelated navigation or filler content reduces the odds it's captured accurately.
Yes, running your live URL through a markdown-conversion tool (many readability and scraping libraries expose this) shows exactly what a retrieval pipeline would extract, revealing collapsed headings or lost structure before it affects how a model describes you.
Only if the content is present in the rendered DOM at crawl time; markdown conversion typically operates on rendered or server-delivered HTML, so client-side content injected after the fact frequently gets stripped out entirely.
