Compression

gzip or brotli cuts HTML bytes on the wire and speeds up both users and crawlers.

Pass condition in our engine: The response includes gzip, brotli or zstd Content-Encoding.

1. Problem description

Uncompressed HTML wastes time-to-first-byte budget, especially on mobile networks. Search engines crawl more slowly through heavy origins. Many hosts leave compression off on HTML while enabling it only for assets.

2. Most common causes

  • nginx/Apache gzip is disabled for text/html.
  • A misconfigured CDN strips Content-Encoding.
  • The origin is a tiny static host without compression middleware.

3. How to fix it

  1. Enable gzip or brotli for HTML, CSS, JS and JSON.
  2. Verify Content-Encoding: br or gzip in DevTools → Network.
  3. Compress at the CDN edge if the origin cannot.
