PWA - Manifest

Manifest is not valid

Your site don't have valid manifest.json, read more in Web App Manifest

Desktop

Serve images in next-gen formats Potential savings of 747 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 Meaningful Paint 3.7 s

First Meaningful Paint measures when the primary content of a page is visible

Remove unused JavaScript Potential savings of 1,585 KiB

Remove unused JavaScript to reduce bytes consumed by network activity

Avoid enormous network payloads Total size was 5,453 KiB

Large network payloads cost users real money and are highly correlated with long load times

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 main-thread work 2.1 s

Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this

First CPU Idle 4.7 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 380 ms

Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds

Max Potential First Input Delay 370 ms

The maximum potential First Input Delay that your users could experience is the duration of the longest task

Serve static assets with an efficient cache policy 39 resources found

A long cache lifetime can speed up repeat visits to your page

Use video formats for animated content Potential savings of 658 KiB

Large GIFs are inefficient for delivering animated content. Consider using MPEG4/WebM videos for animations and PNG/WebP for static images instead of GIF to save network bytes

Avoid large layout shifts 5 elements found

These DOM elements contribute most to the CLS of the page.

Initial server response time was short Root document took 140 ms

Keep the server response time for the main document short because all other requests depend on it

Time to Interactive 5.1 s

Time to interactive is the amount of time it takes for the page to become fully interactive

Avoid serving legacy JavaScript to modern browsers Potential savings of 11 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

Includes front-end JavaScript libraries with known security vulnerabilities 2 vulnerabilities detected

Some third-party scripts may contain known security vulnerabilities that are easily identified and exploited by attackers

Keep request counts low and transfer sizes small 80 requests • 5,453 KiB

To set budgets for the quantity and size of page resources, add a budget.json file

Eliminate render-blocking resources Potential savings of 3,050 ms

Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles

Replace unnecessarily large JavaScript libraries 1 large library found

Large JavaScript libraries can lead to poor performance. Prefer smaller, functionally equivalent libraries to reduce your bundle size

First Contentful Paint 3.7 s

First Contentful Paint marks the time at which the first text or image is painted

User Timing marks and measures 1 user timing

Consider instrumenting your app with the User Timing API to measure your app's real-world performance during key user experiences

Remove unused CSS Potential savings of 404 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

Avoids an excessive DOM size 286 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)

Largest Contentful Paint element 1 element found

This is the largest contentful element painted within the viewport

Avoid long main-thread tasks 9 long tasks found

Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay

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

Minimize third-party usage Third-party code blocked the main thread for 70 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

Reduce JavaScript execution time 1.4 s

Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this

Cumulative Layout Shift 0.251

Cumulative Layout Shift measures the movement of visible elements within the viewport

Speed Index 3.7 s

Speed Index shows how quickly the contents of a page are visibly populated

Page load is not fast enough on mobile networks Interactive on simulated mobile network at 26.0 s

A fast page load over a cellular network ensures a good mobile user experience

Avoid chaining critical requests 15 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

Efficiently encode images Potential savings of 194 KiB

Optimized images load faster and consume less cellular data

Estimated Input Latency 110 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

Largest Contentful Paint 7.1 s

Largest Contentful Paint marks the time at which the largest text or image is painted

Minify CSS Potential savings of 80 KiB

Minifying CSS files can reduce network payload sizes

Enable text compression Potential savings of 2,267 KiB

Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes

Mobile

Document uses legible font sizes 100% legible text

Font sizes less than 12px are too small to be legible and require mobile visitors to “pinch to zoom” in order to read. Strive to have >60% of page text ≥12px

Avoid enormous network payloads Total size was 4,448 KiB

Large network payloads cost users real money and are highly correlated with long load times

Avoid long main-thread tasks 14 long tasks found

Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay

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

Tap targets are not sized appropriately 74% appropriately sized tap targets

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

Enable text compression Potential savings of 2,267 KiB

Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes

Estimated Input Latency 500 ms

Reduce the impact of third-party code Third-party code blocked the main thread for 340 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

Avoid chaining critical requests 15 chains found

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
