What this is

We look for a clear definition sentence on the page: one sentence that says directly what a term is.

Why it matters

When someone asks an AI "what is X", it most often quotes a sentence that defines X in one go. A clear definition makes the page more likely to be used as the source of the answer.

What counts as passing

Passes when a sentence like "X is / means / refers to Y" (or the Chinese 「X 是/指/為 Y」) is found; otherwise fails. Not scored when the main content has fewer than 200 words. Chinese detection is currently strict: 是/指/為 must be followed by a space, so ordinary Chinese sentences may not be recognized.

Suggestion

Pro plan only

Add an explicit definition

No definition pattern detected ('X is Y', 'X 是 Y', 'X refers to Y'). Include an explicit definition sentence so AI engines can quote what the page is about.
