Remove unused CSS Potential savings of 33 KiB
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
JavaScript execution time 0.5 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
Serve static assets with an efficient cache policy 6 resources found
A long cache lifetime can speed up repeat visits to your page
Largest Contentful Paint element 1 element found
This is the largest contentful element painted within the viewport
Avoid chaining critical requests 21 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
Avoids an excessive DOM size 487 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)
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
Minimizes main-thread work 1.2 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this
Avoids enormous network payloads Total size was 1,419 KiB
Large network payloads cost users real money and are highly correlated with long load times
Avoid serving legacy JavaScript to modern browsers Potential savings of 7 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
Speed Index 1.7 s
Speed Index shows how quickly the contents of a page are visibly populated
First CPU Idle 2.4 s
First CPU Idle marks the first time at which the page's main thread is quiet enough to handle input. [Learn more](https://web.dev/first-cpu-idle/).
Total Blocking Time 30 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
Server Backend Latencies 0 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
Avoid long main-thread tasks 2 long tasks found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay
Cumulative Layout Shift 0.205
Cumulative Layout Shift measures the movement of visible elements within the viewport
Preload key requests Potential savings of 110 ms
Consider using `<link rel=preload>` to prioritize fetching resources that are currently requested later in page load
Max Potential First Input Delay 70 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
First Meaningful Paint 0.9 s
First Meaningful Paint measures when the primary content of a page is visible
Remove unused JavaScript Potential savings of 463 KiB
Remove unused JavaScript to reduce bytes consumed by network activity
Properly size images Potential savings of 75 KiB
Serve images that are appropriately-sized to save cellular data and improve load time
Serve images in next-gen formats Potential savings of 98 KiB
Image formats like JPEG 2000, JPEG XR, and WebP often provide better compression than PNG or JPEG, which means faster downloads and less data consumption
First Contentful Paint 0.8 s
First Contentful Paint marks the time at which the first text or image is painted
Avoid non-composited animations 1 animated element found
Animations which are not composited can be janky and increase CLS
Avoid large layout shifts 5 elements found
These DOM elements contribute most to the CLS of the page.

Keep the server response time for the main document short because all other requests depend on it
Keep request counts low and transfer sizes small 94 requests • 1,419 KiB
To set budgets for the quantity and size of page resources, add a budget.json file
Time to Interactive 3.0 s

Eliminate render-blocking resources Potential savings of 300 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
Estimated Input Latency 10 ms
Estimated Input Latency is an estimate of how long your app takes to respond to user input, in milliseconds, during the busiest 5s window of page load. If your latency is higher than 50 ms, users may perceive your app as laggy
Minify JavaScript Potential savings of 3 KiB
Minifying JavaScript files can reduce payload sizes and script parse time
Network Round Trip Times 0 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
Minimize third-party usage Third-party code blocked the main thread for 20 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
Use HTTP/2 19 requests not served via HTTP/2
HTTP/2 offers many benefits over HTTP/1.1, including binary headers and multiplexing
Largest Contentful Paint 1.1 s
Largest Contentful Paint marks the time at which the largest text or image is painted

Mobile

Minify CSS Potential savings of 3 KiB
Minifying CSS files can reduce network payload sizes
Defer offscreen images Potential savings of 132 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive
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

Interactive elements like buttons and links should be large enough (48x48px), and have enough space around them, to be easy enough to tap without overlapping onto other elements
Avoids an excessive DOM size 487 elements
