概要
Crawlability is the foundation layer. Before content, schema, or performance can matter, crawlers need a stable map of canonical URLs that return usable responses.
工作原理
FixWeb combines robots.txt, sitemap discovery, rendered page status, final URLs, canonical tags, and robots meta directives from the browser crawl.
影响范围
A single accidental noindex, broken sitemap, or cross-host canonical can suppress important pages even when the page looks fine to a human visitor.

FixWeb 如何检测
FixWeb fetches robots.txt and sitemap.xml, renders discovered pages, records HTTP status and final URLs, and inspects rendered meta robots and canonical tags.
铁壁防御
Publish a valid sitemap, reference it from robots.txt, keep canonical tags self-consistent, remove accidental noindex directives, and monitor 4xx/5xx responses on important templates.
