Why this matters
Render-blocking CSS and JavaScript delay page load, hindering user experience and Core Web Vitals, which affects SEO performance.
Hypothetical standard operating procedure
Adapt this example to your site, access, tools, and change process. It is our suggested procedure, informed by the sources below.
- Use developer tools like Chrome DevTools to identify render-blocking CSS and JS on category pages.
- Minimize CSS and JavaScript files by removing unused code and compressing files.
- Defer or asynchronously load non-critical JavaScript to prevent blocking the main thread.
- Inline critical CSS needed for above-the-fold content and defer the rest.
- Test category page load performance after changes to confirm improvements and monitor Core Web Vitals metrics.
Watch for
Excessive render-blocking scripts can cause slow Largest Contentful Paint and poor page responsiveness.
Definition of done
Page load tests show no critical render-blocking resources delaying initial content display.
