Desktop

Largest Contentful Paint 2.6 s

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

Avoid non-composited animations 6 animated elements found

Animations which are not composited can be janky and increase CLS

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 470 ms

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

Cumulative Layout Shift 0.154

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

Speed Index 0.9 s

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

First Meaningful Paint 0.8 s

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

First Contentful Paint 0.8 s

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

Server Backend Latencies 110 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 enormous network payloads Total size was 12,863 KiB

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

Max Potential First Input Delay 50 ms

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

Reduce unused CSS Potential savings of 164 KiB

Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity

Network Round Trip Times 10 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

Minimizes main-thread work 1.0 s

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

Time to Interactive 1.3 s

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

Reduce unused JavaScript Potential savings of 408 KiB

Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity

Avoid chaining critical requests 6 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

Properly size images Potential savings of 1,334 KiB

Serve images that are appropriately-sized to save cellular data and improve load time

Initial server response time was short Root document took 10 ms

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

Serve static assets with an efficient cache policy 50 resources found

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

Largest Contentful Paint element 2,620 ms

This is the largest contentful element painted within the viewport

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

Links do not have descriptive text 8 links found

Descriptive link text helps search engines understand your content

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

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

Efficiently encode images Potential savings of 290 KiB

Optimized images load faster and consume less cellular data

Avoid serving legacy JavaScript to modern browsers Potential savings of 0 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

Avoids an excessive DOM size 778 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 large layout shifts 5 elements found

These DOM elements contribute most to the CLS of the page

Enable text compression Potential savings of 190 KiB

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

JavaScript execution time 0.3 s

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

Serve images in next-gen formats Potential savings of 2,382 KiB

Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption

Mobile

Avoid serving legacy JavaScript to modern browsers Potential savings of 0 KiB

Cumulative Layout Shift 0.321

Reduce unused JavaScript Potential savings of 409 KiB

Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity

Web app manifest or service worker do not meet the installability requirements 1 reason

Defer offscreen images Potential savings of 195 KiB

Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive

Serve images in next-gen formats Potential savings of 2,382 KiB

Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption

Avoid long main-thread tasks 16 long tasks found

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

Initial server response time was short Root document took 10 ms

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

Speed Index 4.9 s

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

Avoid non-composited animations 6 animated elements found

Animations which are not composited can be janky and increase CLS

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

First Meaningful Paint 3.3 s

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

First Contentful Paint 3.3 s

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

Links do not have descriptive text 8 links found

Server Backend Latencies 110 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

Eliminate render-blocking resources Potential savings of 2,200 ms

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

Largest Contentful Paint element 9,750 ms

This is the largest contentful element painted within the viewport

Tap targets are sized appropriately 100% 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 chaining critical requests 6 chains found

Efficiently encode images Potential savings of 290 KiB

Optimized images load faster and consume less cellular data

Enable text compression Potential savings of 190 KiB
