Speed optimization toolkit

The theme ships with a speed toolkit that helps pages reach high PageSpeed scores while keeping every feature. It is configured under the HP Theme menu in the admin.

Main optimizations (enabled by default)

  • Delaying third-party scripts (GTM / Google Analytics / Ads / Facebook): loaded only on the visitor's first interaction (scroll/touch/mouse move) - greatly reducing initial load time while still keeping ad conversion tracking.
  • PurgeCSS-processed CSS: only the CSS that is actually used is loaded (with a separate build for the shop page) → less render-blocking size.
  • Async CSS on mobile (desktop stays blocking to avoid layout shift / CLS = 0).
  • Font preloading, CDN preconnect, blocking of unnecessary thumbnail generation, caching of homepage blocks...

Operating notes

  • Logged-in admins bypass the page cache → the homepage and PDP loading slower than for anonymous visitors is normal.
  • After changing the design or content, if you still see old CSS → clear the cache (WP Fastest Cache) and reload.

Don't enable another optimization plugin on top (it easily conflicts with minify/critical CSS). The theme already handles this part.
