Desktop

Desktop Screenshot
Avoid large layout shifts 5 elements found
These DOM elements contribute most to the CLS of the page.
Efficiently encode images Potential savings of 327 KiB
Optimized images load faster and consume less cellular data
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
Time to Interactive 0.8 s
Time to interactive is the amount of time it takes for the page to become fully interactive
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
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
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
Avoid non-composited animations 1 animated element found
Animations which are not composited can be janky and increase CLS
Uses efficient cache policy on static assets 1 resource found
A long cache lifetime can speed up repeat visits to your page
Remove unused JavaScript Potential savings of 22 KiB
Remove unused JavaScript to reduce bytes consumed by network activity
Avoids enormous network payloads Total size was 879 KiB
Large network payloads cost users real money and are highly correlated with long load times
Speed Index 3.1 s
Speed Index shows how quickly the contents of a page are visibly populated
Total Blocking Time 0 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
Eliminate render-blocking resources Potential savings of 500 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
First Meaningful Paint 0.8 s
First Meaningful Paint measures when the primary content of a page is visible
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
Cumulative Layout Shift 0.01
Cumulative Layout Shift measures the movement of visible elements within the viewport
Keep request counts low and transfer sizes small 30 requests • 879 KiB
To set budgets for the quantity and size of page resources, add a budget.json file
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 2,460 ms
Keep the server response time for the main document short because all other requests depend on it
Remove unused CSS Potential savings of 16 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
Properly size images Potential savings of 8 KiB
Serve images that are appropriately-sized to save cellular data and improve load time
First CPU Idle 0.8 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/).
Largest Contentful Paint element 1 element found
This is the largest contentful element painted within the viewport
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
Serve images in next-gen formats Potential savings of 492 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
Largest Contentful Paint 1.2 s
Largest Contentful Paint marks the time at which the largest text or image is painted
JavaScript execution time 0.1 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
Avoids an excessive DOM size 792 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 0.8 s
First Contentful Paint marks the time at which the first text or image is painted
Max Potential First Input Delay 30 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task

Mobile

Mobile Screenshot
Uses efficient cache policy on static assets 1 resource found
A long cache lifetime can speed up repeat visits to your page
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
Efficiently encode images Potential savings of 327 KiB
Optimized images load faster and consume less cellular data
Keep request counts low and transfer sizes small 30 requests • 879 KiB
To set budgets for the quantity and size of page resources, add a budget.json file
Largest Contentful Paint 5.6 s
Largest Contentful Paint marks the time at which the largest text or image is painted
Document uses legible font sizes 98.57% 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 non-composited animations 19 animated elements found
Animations which are not composited can be janky and increase CLS
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
Serve images in next-gen formats Potential savings of 492 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
Minimize main-thread work 3.3 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
First Contentful Paint (3G) 6090 ms
First Contentful Paint 3G marks the time at which the first text or image is painted while on a 3G network
Speed Index 7.5 s
Speed Index shows how quickly the contents of a page are visibly populated
Server Backend Latencies 0 ms

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
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
