Opportunities for improvement
Efficiently encode images: Optimized images load faster and consume less cellular data. [Learn more](https://web.dev/uses-optimized-images/).
Potential savings of 5,200 KiB
Minify CSS: Minifying CSS files can reduce network payload sizes. [Learn more](https://web.dev/unminified-css/).
Potential savings of 11 KiB
Eliminate render-blocking resources: Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles. [Learn more](https://web.dev/render-blocking-resources/).
Potential savings of 4,820 ms
Enable text compression: Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. [Learn more](https://web.dev/uses-text-compression/).
Potential savings of 82 KiB
Remove unused CSS: Remove dead rules from stylesheets and defer the loading of CSS not used for above-the-fold content to reduce unnecessary bytes consumed by network activity. [Learn more](https://web.dev/unused-css-rules/).
Potential savings of 14 KiB
Potential savings of 21 KiB
