Response not compressed

Text compression shrinks HTML, CSS, and JS dramatically, often by 70% or more, for free.

What it is

This check flags text-based responses served without gzip or brotli compression.

Why it matters for SEO

Uncompressed text wastes bandwidth, slows loading, and increases emissions, all avoidable with a config change.

Example

/app.js served without Content-Encoding (gzip/br)

How to fix

1. Enable gzip or brotli on your server or CDN.
2. Confirm a Content-Encoding header is returned for text assets.
3. Combine with minification for maximum savings.
4. Re-crawl to confirm assets are compressed.
