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

Speed Index 0.6 s

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

Reduce unused CSS Potential savings of 35 KiB

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

Avoids enormous network payloads Total size was 640 KiB

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

Includes front-end JavaScript libraries with known security vulnerabilities 5 vulnerabilities detected

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

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 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

First Meaningful Paint 0.5 s

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

Serve static assets with an efficient cache policy 31 resources found

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

Initial server response time was short Root document took 480 ms

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

JavaScript execution time 0.0 s

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

Keep request counts low and transfer sizes small 33 requests • 640 KiB

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

Reduce unused JavaScript Potential savings of 36 KiB

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

Avoids an excessive DOM size 172 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)

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

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

Time to Interactive 0.5 s

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

First Contentful Paint 0.5 s

Avoid large layout shifts 5 elements found

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

Eliminate render-blocking resources Potential savings of 210 ms

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

Minimizes main-thread work 0.2 s

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

Cumulative Layout Shift 0.055

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

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

Avoid chaining critical requests 4 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

Largest Contentful Paint 0.5 s

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

Largest Contentful Paint element 1 element found

This is the largest contentful element painted within the viewport

Total Blocking Time 0 ms

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

Mobile

First Meaningful Paint 1.6 s

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

Avoids an excessive DOM size 170 elements

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

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

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 3 long tasks found

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

Tap targets are not sized appropriately 11% 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

Reduce unused CSS Potential savings of 36 KiB
