Page has redirected CSS

CSS is render-blocking, so a redirected stylesheet URL delays the moment the page becomes visible.

What it is

This check flags <link rel='stylesheet'> values that resolve through a 3xx redirect.

Why it matters for SEO

Redirected stylesheets push back first paint and Largest Contentful Paint, weakening performance scores.

Example

/css/app.css  ->  301  /css/app.min.css

How to fix

1. Reference the final stylesheet URL.
2. Update templates and build output.
3. Keep the redirect only for legacy references.
4. Re-crawl to confirm CSS loads without redirects.
