Desktop

Remove unused CSS Potential savings of 66 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

Serve images in next-gen formats Potential savings of 111 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

Does not use HTTPS 43 insecure requests found

All sites should be protected with HTTPS, even ones that don't handle sensitive data. HTTPS prevents intruders from tampering with or passively listening in on the communications between your app and your users, and is a prerequisite for HTTP/2 and many new web platform APIs

Server response times are low (TTFB) Root document took 300 ms

Time To First Byte identifies the time at which your server sends a response

Eliminate render-blocking resources Potential savings of 30 ms

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

Enable text compression Potential savings of 131 KB

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

Efficiently encode images Potential savings of 118 KB

Optimized images load faster and consume less cellular data

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

Total Blocking Time 0 ms

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

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

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

Properly size images Potential savings of 299 KB

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

Speed Index 1.2 s

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

First CPU Idle 0.7 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).

Avoids enormous network payloads Total size was 945 KB

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

Minimizes main-thread work 0.4 s

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

First Contentful Paint 0.7 s

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

Includes front-end JavaScript libraries with known security vulnerabilities 3 vulnerabilities detected

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

Avoid chaining critical requests 9 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

Avoids an excessive DOM size 810 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 Meaningful Paint 0.7 s

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

Keep request counts low and transfer sizes small 63 requests • 945 KB

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

Use video formats for animated content Potential savings of 230 KB

Large GIFs are inefficient for delivering animated content. Consider using MPEG4/WebM videos for animations and PNG/WebP for static images instead of GIF to save network bytes

Serve static assets with an efficient cache policy 54 resources found

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

Max Potential First Input Delay 20 ms

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

Time to Interactive 0.7 s

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

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

Mobile

Minimize third-party usage Third-party code blocked the main thread for 90 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

Total Blocking Time 100 ms

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

JavaScript execution time 0.7 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 160 KB

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

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

Properly size images Potential savings of 252 KB

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

Speed Index 3.2 s

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

First CPU Idle 3.8 s

Time to Interactive 4.3 s

Time to interactive is the amount of time it takes for the page to become fully 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) 6204 ms

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

Estimated Input Latency 10 ms

Tap targets are not sized appropriately 37% 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

Document doesn't use legible font sizes 35.71% 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
