Why it matters
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.
How it works
FixWeb checks rendered viewport metadata, hreflang links, manifest links, and language declarations captured by the crawler.
Site impact
Weak mobile configuration hurts usability; broken hreflang confuses locale targeting; missing manifest metadata limits app-like experiences.

How FixWeb tests for it
The rendered snapshot records viewport, html lang, rel=alternate hreflang links, and rel=manifest references.
How to improve
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.
