Main content takes too long to appear, above Google's 2.5s threshold.

CWV-RENDER-BLOCK-CSS-001

Render-Blocking CSS Detected

External CSS stylesheets block page rendering until they are downloaded and parsed. This delays First Contentful Paint and LCP.

CWV-RENDER-BLOCK-JS-001

Render-Blocking JavaScript Detected

Synchronous <script> tags in the <head> block page rendering. The browser must download and execute these scripts before painting any content.

CWV-SRCSET-SIZES-001

Responsive Images Missing srcset or sizes Attributes

Images are served without srcset or sizes attributes, forcing browsers to download full-size images regardless of the viewport. This wastes bandwidth on mobile and smaller screens.

CWV-UNUSED-CSS-001

Significant Unused CSS

A large portion of downloaded CSS is unused on this page. Unused CSS increases download size and adds to render-blocking time.

CWV-UNUSED-JS-001

Significant Unused JavaScript
