Text content on your page isn't being compressed before it's sent to visitors' browsers, adding unnecessary load time on every visit.
On WordPress
Most managed WordPress hosts (WP Engine, Kinsta, SiteGround) enable Gzip by default. If yours doesn't, WP Rocket or Autoptimize can enable it. Alternatively, enable it via Cloudflare for free.
On Shopify
Shopify enables Gzip automatically for all stores — this issue appearing on a Shopify site is unusual and may indicate a third-party proxy in front of the store.
Pro tip: Enabling Brotli (available on most modern servers) typically compresses 15–20% better than Gzip. Enable it instead of Gzip if your server supports it.
