Remove unused JavaScript
Potential savings of 234 KiBReduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
Efficiently encode images
Potential savings of 89 KiBOptimized images load faster and consume less cellular data.
Eliminate render-blocking resources
Potential savings of 320 msResources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.
Enable text compression
Potential savings of 42 KiBText-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes.
