Why does llms.txt with an entity definition, key facts and explicit negative statements matter?

The negative statements block is the most useful part: it is how you stop an engine conflating you with a similarly named product. The file costs one route. Verify it: Run `curl -s https://example.com/llms.txt | head -30` and confirm an entity paragraph, a key-facts list and a 'what this is not' section.

Why does llms-full.txt with a categorised content index and one-line summaries matter?

It gives a retrieval system the shape of the site in one fetch instead of requiring it to crawl and infer structure. Verify it: Run `curl -s https://example.com/llms-full.txt | grep -c '^- \['` and confirm the count is close to the number of indexable content URLs.

Why does a canonical Q&A block pairing each likely question with an approved answer and its source URL matter?

If you do not write the answer, the engine writes it from whatever fragment it found. This is the cheapest control you have over how you are described. Verify it: Confirm the canonical answers section exists and that each answer carries a Source line pointing at a real URL.

Why does answers are self-contained sentences that restate their subject matter?

An extracted sentence has to stand alone as a citable fact. 'Acme covers 70 checks' survives extraction; 'we cover 70 checks' does not, because the subject is lost. Verify it: Take any FAQ answer out of context and read it. If it starts with we, it, this or that, rewrite it.

Why does explicit citation guidance: which URL to cite, how to qualify volatile facts, where to defer matter?

Pricing changes. A model that cached a price and states it flatly is doing damage. Telling it to link rather than assert is the fix, and nobody else is writing this down. Verify it: Confirm llms-full.txt contains a citation guidance section naming a preferred URL and a volatile-fact policy.

Why does an entity disambiguation section naming what you are commonly confused with matter?

Entity confusion is the single most common AEO failure and the easiest to prevent. One sentence per confusable entity. Verify it: Confirm llms-full.txt has a disambiguation section with at least two entries.

Why does a monthly citation check against a fixed set of seed queries matter?

AEO is the boldest claim most sites now make and almost nobody measures it. A fixed query set run monthly turns the claim into a trend line. Verify it: Run the citation check script and confirm it writes a dated JSON snapshot naming which engines cited the site.
