Enable gzip (or brotli) compression on the server

Symptom

BoltAudit reports text responses without a content-encoding: gzip (or br) header. Lighthouse's "Enable text compression" audit catches this.

Impact

• Every HTML/CSS/JS response is 3–4× larger than it needs to be.
• On slow mobile networks, this directly translates to slower LCP.
• CDN bandwidth bills are higher than they should be.

Manual fix

Apache (.htaccess)

CODE0

NGINX

CODE1

For brotli (better ratio), most managed hosts and Cloudflare enable it automatically. On self-managed NGINX you need the ngx_brotli module.

Apply Fix

One-click in the dashboard for Apache stacks where the snippet can be appended to .htaccess. For NGINX, the dashboard shows the config you need to add and the nginx -s reload command.

Verify

CODE2

You should see content-encoding: gzip or content-encoding: br.
