Page has broken CSS

A missing stylesheet strips a page of its design, leaving raw, unstyled content for users and crawlers.

What it is

This check flags <link rel='stylesheet'> references that return an error such as 404.

Why it matters for SEO

Unstyled pages look broken, raise bounce rate, and can shift layout dramatically, hurting UX and Core Web Vitals.

Example

<link rel='stylesheet' href='/css/app.css'>   ->  404 Not Found

How to fix

1. Restore the file or fix the href path.
2. Check hashed filenames from your build pipeline.
3. Remove references to stylesheets you no longer ship.
4. Re-crawl to confirm styles load.
