Quick overview:
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Eliminate render-blocking resources
Potential savings of 1,650 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles. Learn how to eliminate render-blocking resources.
Efficiently encode images
Potential savings of 220 KiB
Optimized images load faster and consume less cellular data. Learn how to efficiently encode images.
Reduce initial server response time
Root document took 710 ms
Keep the server response time for the main document short because all other requests depend on it. Learn more about the Time to First Byte metric.
Minify CSS
Potential savings of 9 KiB
Minifying CSS files can reduce network payload sizes. Learn how to minify CSS.
Reduce unused JavaScript
Potential savings of 43 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity. Learn how to reduce unused JavaScript.
Largest Contentful Paint element
3,970 ms
This is the largest contentful element painted within the viewport. Learn more about the Largest Contentful Paint element
Serve images in next-gen formats
Potential savings of 294 KiB
Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption. Learn more about modern image formats.
Reduce unused CSS
Potential savings of 53 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity. Learn how to reduce unused CSS.
Serve static assets with an efficient cache policy
20 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more about efficient cache policies.
Minify JavaScript
Potential savings of 4 KiB
Minifying JavaScript files can reduce payload sizes and script parse time. Learn how to minify JavaScript.
Defer offscreen images
Potential savings of 5 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive. Learn how to defer offscreen images.
Does not use passive listeners to improve scrolling performance
Consider marking your touch and wheel event listeners as `passive` to improve your page's scroll performance. Learn more about adopting passive event listeners.
Avoid serving legacy JavaScript to modern browsers
Potential savings of 0 KiB
Polyfills and transforms enable legacy browsers to use new JavaScript features. However, many aren't necessary for modern browsers. For your bundled JavaScript, adopt a modern script deployment strategy using module/nomodule feature detection to reduce the amount of code shipped to modern browsers, while retaining support for legacy browsers. Learn how to serve modern JavaScript
Insights
Optimize viewport for mobile
Tap interactions may be delayed by up to 300 ms if the viewport is not optimized for mobile.
Document request latency
Your first network request is the most important. Reduce its latency by avoiding redirects, ensuring a fast server response, and enabling text compression.
Render blocking requests
Requests are blocking the page's initial render, which may delay LCP. Deferring or inlining can move these network requests out of the critical path.
Improve image delivery
Reducing the download time of images can improve the perceived load time of the page and LCP. Learn more about optimizing image size
Time to Interactive
4.0 s
Time to Interactive is the amount of time it takes for the page to become fully interactive. Learn more about the Time to Interactive metric.

22 insecure requests found
All sites should be protected with HTTPS, even ones that don't handle sensitive data. This includes avoiding mixed content, where some resources are loaded over HTTP despite the initial request being served over HTTPS. HTTPS prevents intruders from tampering with or passively listening in on the communications between your app and your users, and is a prerequisite for HTTP/2 and many new web platform APIs. Learn more about HTTPS.
