概要
A good site should tell browsers and crawlers which language it is, how it adapts to mobile screens, and whether it behaves like an installable app.
仕組み
FixWeb checks rendered viewport metadata, hreflang links, manifest links, and language declarations captured by the crawler.
被害範囲
Weak mobile configuration hurts usability; broken hreflang confuses locale targeting; missing manifest metadata limits app-like experiences.

FixWebのテスト方法
The rendered snapshot records viewport, html lang, rel=alternate hreflang links, and rel=manifest references.
鉄壁の防御
Set a mobile viewport, keep hreflang complete and reciprocal, set html lang for each locale, and add a manifest when the site should be installable.
