Gzip compresses your pages before sending them, so they download faster.

1. Check the cPanel tool: go to Software > Optimize Website, choose Compress All Content, and save.
2. Or via .htaccess: add a mod_deflate block to compress text, HTML, CSS, and JavaScript.
3. WordPress: most caching plugins (article 168) can enable Gzip for you.
4. Test with an online Gzip checker to confirm it's active.

Tip: Gzip can shrink text-based files significantly with no visible change to your site — an easy speed win.
