Desktop Screenshot
Serve images in next-gen formats Potential savings of 456 KiB
Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption
Initial server response time was short Root document took 90 ms
Keep the server response time for the main document short because all other requests depend on it
Server Backend Latencies 190 ms
Server latencies can impact web performance. If the server latency of an origin is high, it's an indication the server is overloaded or has poor backend performance
Serve static assets with an efficient cache policy 48 resources found
A long cache lifetime can speed up repeat visits to your page
Largest Contentful Paint element 1,730 ms
This is the largest contentful element painted within the viewport
Eliminate render-blocking resources Potential savings of 240 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
Reduce unused CSS Potential savings of 38 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity
Uses deprecated APIs 1 warning found
Deprecated APIs will eventually be removed from the browser
Largest Contentful Paint 1.7 s
Largest Contentful Paint marks the time at which the largest text or image is painted
Defer offscreen images Potential savings of 4 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive
Avoid multiple page redirects Potential savings of 230 ms
Redirects introduce additional delays before the page can be loaded
Avoid large layout shifts 3 elements found
These DOM elements were most affected by layout shifts. Some layout shifts may not be included in the CLS metric value due to [windowing](https://web.dev/articles/cls#what_is_cls)
Reduce unused JavaScript Potential savings of 770 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity
Reduce JavaScript execution time 2.9 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
Avoid long main-thread tasks 18 long tasks found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay
User Timing marks and measures 6 user timings
Consider instrumenting your app with the User Timing API to measure your app's real-world performance during key user experiences
Uses third-party cookies 18 cookies found
Support for third-party cookies will be removed in a future version of Chrome
Network Round Trip Times 50 ms
Network round trip times (RTT) have a large impact on performance. If the RTT to an origin is high, it's an indication that servers closer to the user could improve performance
First Meaningful Paint 0.9 s
First Meaningful Paint measures when the primary content of a page is visible
Minimize main-thread work 5.5 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this
Properly size images Potential savings of 47 KiB
Serve images that are appropriately-sized to save cellular data and improve load time
Enable text compression Potential savings of 75 KiB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes
Avoid an excessive DOM size 1,452 elements
A large DOM will increase memory usage, cause longer [style calculations](https://developers.google.com/web/fundamentals/performance/rendering/reduce-the-scope-and-complexity-of-style-calculations), and produce costly [layout reflows](https://developers.google.com/speed/articles/reflow)
Avoid non-composited animations 1 animated element found
Animations which are not composited can be janky and increase CLS
First Contentful Paint 0.9 s
First Contentful Paint marks the time at which the first text or image is painted
Time to Interactive 5.5 s
Time to Interactive is the amount of time it takes for the page to become fully interactive
Max Potential First Input Delay 270 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
Avoid enormous network payloads Total size was 3,588 KiB
Large network payloads cost users real money and are highly correlated with long load times
Total Blocking Time 730 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
Web app manifest or service worker do not meet the installability requirements 1 reason
Service worker is the technology that enables your app to use many Progressive Web App features, such as offline, add to homescreen, and push notifications. With proper service worker and manifest implementations, browsers can proactively prompt users to add your app to their homescreen, which can lead to higher engagement
Avoid serving legacy JavaScript to modern browsers Potential savings of 32 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
Avoid chaining critical requests 5 chains found
The Critical Request Chains below show you what resources are loaded with a high priority. Consider reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load
Speed Index 2.7 s
Speed Index shows how quickly the contents of a page are visibly populated
Cumulative Layout Shift 0.061
Cumulative Layout Shift measures the movement of visible elements within the viewport
Minimize third-party usage Third-party code blocked the main thread for 190 ms
Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading
Minify JavaScript Potential savings of 6 KiB
Minifying JavaScript files can reduce payload sizes and script parse time

Avoid serving legacy JavaScript to modern browsers Potential savings of 19 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
Tap targets are not sized appropriately 88% appropriately sized tap targets
Interactive elements like buttons and links should be large enough (48x48px), or have enough space around them, to be easy enough to tap without overlapping onto other elements
Avoid enormous network payloads Total size was 4,279 KiB
Large network payloads cost users real money and are highly correlated with long load times
First Meaningful Paint 3.0 s
