概要
Schema cannot rescue weak content, but valid schema can remove ambiguity around products, organizations, local businesses, videos, articles, breadcrumbs, and profiles.
工作原理
FixWeb parses rendered application/ld+json blocks, records schema types, and highlights invalid JSON-LD or missing homepage identity schema.
影响范围
Invalid schema is ignored. Missing entity cues can make rich-result eligibility and answer extraction weaker than they need to be.

FixWeb 如何检测
The crawler parses JSON-LD in the browser-rendered DOM and records syntax errors plus detected @type values.
铁壁防御
Emit valid JSON-LD that matches visible page content. Validate with schema.org or rich-result tooling and avoid site-wide boilerplate schema that lies about page type.
