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 0.0 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 339 KB
Serve images that are appropriately-sized to save cellular data and improve load time
Speed Index 6.4 s
Speed Index shows how quickly the contents of a page are visibly populated
First CPU Idle 0.8 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).
Avoid enormous network payloads Total size was 3,412 KB
Large network payloads cost users real money and are highly correlated with long load times
Minimizes main-thread work 0.8 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this
robots.txt is not valid 1 error found
If your robots.txt file is malformed, crawlers may not be able to understand how you want your website to be crawled or indexed
First Contentful Paint 0.7 s
First Contentful Paint marks the time at which the first text or image is painted
Avoid chaining critical requests 26 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 311 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)
Preload key requests Potential savings of 1,180 ms
Consider using `<link rel=preload>` to prioritize fetching resources that are currently requested later in page load
First Meaningful Paint 0.8 s
First Meaningful Paint measures when the primary content of a page is visible
Keep request counts low and transfer sizes small 145 requests • 3,412 KB
To set budgets for the quantity and size of page resources, add a budget.json file
Serve static assets with an efficient cache policy 61 resources found
A long cache lifetime can speed up repeat visits to your page
Max Potential First Input Delay 30 ms
The maximum potential First Input Delay that your users could experience is the duration, in milliseconds, of the longest task
Time to Interactive 0.8 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
Minify CSS Potential savings of 2 KB
Minifying CSS files can reduce network payload sizes
Remove unused CSS Potential savings of 10 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 411 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 13 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
Reduce server response times (TTFB) Root document took 1,470 ms
Time To First Byte identifies the time at which your server sends a response
Efficiently encode images Potential savings of 278 KB
Optimized images load faster and consume less cellular data

Max Potential First Input Delay 100 ms
The maximum potential First Input Delay that your users could experience is the duration, in milliseconds, of the longest task
Time to Interactive 7.2 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) 4953 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
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
Minify CSS Potential savings of 2 KB
Minifying CSS files can reduce network payload sizes
Tap targets are not sized appropriately 90% 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 uses legible font sizes 97.04% 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 10 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 402 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

Defer offscreen images Potential savings of 354 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 235 KB
Serve images that are appropriately-sized to save cellular data and improve load time
