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
Reduce initial server response time Root document took 1,190 ms
Keep the server response time for the main document short because all other requests depend on it
Total Blocking Time 30 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
Speed Index 2.4 s
Speed Index shows how quickly the contents of a page are visibly populated
Minify JavaScript Potential savings of 40 KiB
Minifying JavaScript files can reduce payload sizes and script parse time
Avoids enormous network payloads Total size was 2,128 KiB
Large network payloads cost users real money and are highly correlated with long load times
Max Potential First Input Delay 110 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
Avoid an excessive DOM size 872 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)
First Contentful Paint 1.0 s
First Contentful Paint marks the time at which the first text or image is painted
Minimize third-party usage Third-party code blocked the main thread for 0 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
First Meaningful Paint 1.0 s
First Meaningful Paint measures when the primary content of a page is visible
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 1 long task found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay
Serve images in next-gen formats Potential savings of 982 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
Properly size images Potential savings of 896 KiB
Serve images that are appropriately-sized to save cellular data and improve load time
Time to Interactive 2.3 s
Time to interactive is the amount of time it takes for the page to become fully interactive
Largest Contentful Paint 3.4 s
Largest Contentful Paint marks the time at which the largest text or image is painted
Avoid large layout shifts 3 elements found
These DOM elements contribute most to the CLS of the page.
First CPU Idle 1.2 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/).
Eliminate render-blocking resources Potential savings of 980 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
Includes front-end JavaScript libraries with known security vulnerabilities 8 vulnerabilities detected
Some third-party scripts may contain known security vulnerabilities that are easily identified and exploited by attackers
Remove unused CSS Potential savings of 31 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
Cumulative Layout Shift 0.001
Cumulative Layout Shift measures the movement of visible elements within the viewport
Keep request counts low and transfer sizes small 108 requests • 2,128 KiB
To set budgets for the quantity and size of page resources, add a budget.json file
Efficiently encode images Potential savings of 742 KiB
Optimized images load faster and consume less cellular data
Remove unused JavaScript Potential savings of 95 KiB
Remove unused JavaScript to reduce bytes consumed by network activity
Avoid chaining critical requests 51 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
Minimizes main-thread work 0.6 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this
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
Largest Contentful Paint element 1 element found
This is the largest contentful element painted within the viewport
Defer offscreen images Potential savings of 3 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive
JavaScript execution time 0.2 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
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
Serve static assets with an efficient cache policy 79 resources found
A long cache lifetime can speed up repeat visits to your page
