Avoids an excessive DOM size 549 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 enormous network payloads Total size was 3,019 KiB
Large network payloads cost users real money and are highly correlated with long load times
Efficiently encode images Potential savings of 16 KiB
Optimized images load faster and consume less cellular data
Reduce unused CSS Potential savings of 125 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity
Minimize main-thread work 2.6 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this
Defer offscreen images Potential savings of 28 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive
Reduce JavaScript execution time 1.4 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this
Reduce initial server response time Root document took 960 ms
Keep the server response time for the main document short because all other requests depend on it
Keep request counts low and transfer sizes small 98 requests • 3,019 KiB
To set budgets for the quantity and size of page resources, add a budget.json file
Serve static assets with an efficient cache policy 39 resources found
A long cache lifetime can speed up repeat visits to your page
Reduce unused JavaScript Potential savings of 1,350 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
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
Largest Contentful Paint 1.2 s
Largest Contentful Paint marks the time at which the largest text or image is painted
Avoid large layout shifts 5 elements found
These DOM elements contribute most to the CLS of the page.
First Contentful Paint 0.8 s
First Contentful Paint marks the time at which the first text or image is painted
Total Blocking Time 490 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds
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
Max Potential First Input Delay 490 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task
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
Serve images in next-gen formats Potential savings of 22 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
Minify JavaScript Potential savings of 7 KiB
Minifying JavaScript files can reduce payload sizes and script parse time
Largest Contentful Paint element 1 element found
This is the largest contentful element painted within the viewport
Avoid serving legacy JavaScript to modern browsers Potential savings of 2 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
Speed Index 1.5 s
Speed Index shows how quickly the contents of a page are visibly populated
Avoid chaining critical requests 25 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 4.6 s
Time to interactive is the amount of time it takes for the page to become fully interactive
Eliminate render-blocking resources Potential savings of 340 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles
Properly size images Potential savings of 419 KiB
Serve images that are appropriately-sized to save cellular data and improve load time
Avoid long main-thread tasks 7 long tasks found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay
First Meaningful Paint 0.8 s
First Meaningful Paint measures when the primary content of a page is visible
Cumulative Layout Shift 0.138
Cumulative Layout Shift measures the movement of visible elements within the viewport
Minimize third-party usage Third-party code blocked the main thread for 30 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

Tap targets are not sized appropriately 42% 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
First Contentful Paint (3G) 5790 ms
First Contentful Paint 3G marks the time at which the first text or image is painted while on a 3G network
Document uses legible font sizes 99.52% 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
