讨论: Structured data with JSON-LD: only what is true
记录
Structured data benefits search engines more than readers, and maintaining it costs time on every content change; if it drifts from the visible content, it can be treated as spam. For small sites without a rich-result use case the honest advice may be to skip it. The article assumes the benefit without stating who gains.
Validation tip: the schema.org validator and the search-engine rich-result tester disagree sometimes, because the latter checks only the subset it uses for rich results. Validate against schema.org for correctness and against the search tool for eligibility; treat warnings from the second as optional.
