Serve images in next-gen formats Potential savings of 129 KB

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

Tap targets are not sized appropriately 100% 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

Avoids enormous network payloads Total size was 1,786 KB

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

Max Potential First Input Delay 720 ms

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

Total Blocking Time 4,620 ms

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

Avoid an excessive DOM size 2,801 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)

Estimated Input Latency 310 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 20 resources found

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

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

Time to Interactive 19.1 s

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

First CPU Idle 16.7 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).

First Contentful Paint 1.1 s

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

Uses deprecated APIs 1 warning found

Deprecated APIs will eventually be removed from the browser

Minify JavaScript Potential savings of 12 KB

Minifying JavaScript files can reduce payload sizes and script parse time

Initial server response time was short Root document took 340 ms

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

First Meaningful Paint 4.8 s

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

Reduce the impact of third-party code Third-party code blocked the main thread for 1,780 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 100 KB

Optimized images load faster and consume less cellular data

Reduce JavaScript execution time 10.7 s

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

Minimize main-thread work 25.4 s

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

Cumulative Layout Shift 0.478

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

Document uses legible font sizes 83.52% 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

Remove unused CSS Potential savings of 83 KB

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

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

Defer offscreen images Potential savings of 67 KB

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

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) 1954 ms

First Contentful Paint 3G marks the time at which the first text or image is painted while on a 3G network

Speed Index 9.0 s

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

Remove unused JavaScript Potential savings of 439 KB

Remove unused JavaScript to reduce bytes consumed by network activity

Largest Contentful Paint 10.4 s

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

Page load is not fast enough on mobile networks Interactive at 19.1 s

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

Keep request counts low and transfer sizes small 166 requests • 1,787 KB

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