Reduce unused JavaScript
Est savings of 50 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity. Learn how to reduce unused JavaScript.
Minify JavaScript
Est savings of 17 KiB
Minifying JavaScript files can reduce payload sizes and script parse time. Learn how to minify JavaScript.
Minimize main-thread work
2.3 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this. Learn how to minimize main-thread work
Properly size images
Est savings of 1,535 KiB
Serve images that are appropriately-sized to save cellular data and improve load time. Learn how to size images.
Serve images in next-gen formats
Est savings of 2,693 KiB
Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption. Learn more about modern image formats.
Eliminate render-blocking resources
Est savings of 970 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles. Learn how to eliminate render-blocking resources.
Largest Contentful Paint element
17,880 ms
This is the largest contentful element painted within the viewport. Learn more about the Largest Contentful Paint element
Avoid serving legacy JavaScript to modern browsers
Est savings of 13 KiB
Polyfills and transforms enable legacy browsers to use new JavaScript features. However, many aren't necessary for modern browsers. Consider modifying your JavaScript build process to not transpile Baseline features, unless you know you must support legacy browsers. Learn why most sites can deploy ES6+ code without transpiling
Avoid enormous network payloads
Total size was 6,297 KiB
Large network payloads cost users real money and are highly correlated with long load times. Learn how to reduce payload sizes.
Does not use passive listeners to improve scrolling performance
Consider marking your touch and wheel event listeners as `passive` to improve your page's scroll performance. Learn more about adopting passive event listeners.
Enable text compression
Est savings of 22 KiB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn more about text compression.
Avoid `document.write()`
For users on slow connections, external scripts dynamically injected via `document.write()` can delay page load by tens of seconds. Learn how to avoid document.write().
Serve static assets with an efficient cache policy
77 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more about efficient cache policies.
Image elements do not have explicit `width` and `height`
Set an explicit width and height on image elements to reduce layout shifts and improve CLS. Learn how to set image dimensions
Use video formats for animated content
Est savings of 1,207 KiB
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. Learn more about efficient video formats
Document request latency
Est savings of 2,630 ms
Your first network request is the most important. Reduce its latency by avoiding redirects, ensuring a fast server response, and enabling text compression.
Render blocking requests
Est savings of 1,750 ms
Requests are blocking the page's initial render, which may delay LCP. Deferring or inlining can move these network requests out of the critical path.
Use efficient cache lifetimes
Est savings of 1,108 KiB
A long cache lifetime can speed up repeat visits to your page. Learn more.
Font display
Est savings of 680 ms
Consider setting font-display to swap or optional to ensure text is consistently visible. swap can be further optimized to mitigate layout shifts with font metric overrides.
Network dependency tree
Avoid chaining critical requests by reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load.
Forced reflow
A forced reflow occurs when JavaScript queries geometric properties (such as offsetWidth) after styles have been invalidated by a change to the DOM state. This can result in poor performance. Learn more about forced reflows and possible mitigations.
LCP request discovery
Optimize LCP by making the LCP image discoverable from the HTML immediately, and avoiding lazy-loading
Improve image delivery
Est savings of 5,079 KiB
Reducing the download time of images can improve the perceived load time of the page and LCP. Learn more about optimizing image size
Legacy JavaScript
Est savings of 13 KiB
Polyfills and transforms enable older browsers to use new JavaScript features. However, many aren't necessary for modern browsers. Consider modifying your JavaScript build process to not transpile Baseline features, unless you know you must support older browsers. Learn why most sites can deploy ES6+ code without transpiling
Time to Interactive
19.6 s
Time to Interactive is the amount of time it takes for the page to become fully interactive. Learn more about the Time to Interactive metric.
Max Potential First Input Delay
130 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task. Learn more about the Maximum Potential First Input Delay metric.

Quick overview:
General
Browser errors were logged to the console
Errors logged to the console indicate unresolved problems. They can come from network request failures and other browser concerns. Learn more about this errors in console diagnostic audit
Issues were logged in the `Issues` panel in Chrome Devtools
Issues logged to the `Issues` panel in Chrome Devtools indicate unresolved problems. They can come from network request failures, insufficient security controls, and other browser concerns. Open up the Issues panel in Chrome DevTools for more details on each issue.
Trust and Safety
Does not use HTTPS
1 insecure request found
All sites should be protected with HTTPS, even ones that don't handle sensitive data. This includes avoiding mixed content, where some resources are loaded over HTTP despite the initial request being served over HTTPS. 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. Learn more about HTTPS.
User Experience
Serves images with low resolution
Image natural dimensions should be proportional to the display size and the pixel ratio to maximize image clarity. Learn how to provide responsive images.
Chanzhijin.com Mobile Accessibility: 82/100
Quick overview:
Names and labels
These are opportunities to improve the semantics of the controls in your application. This may enhance the experience for users of assistive technology, like a screen reader.
Buttons do not have an accessible name
When a button doesn't have an accessible name, screen readers announce it as "button", making it unusable for users who rely on screen readers. Learn how to make buttons more accessible.
`<frame>` or `<iframe>` elements do not have a title
Screen reader users rely on frame titles to describe the contents of frames. Learn more about frame titles.
Links do not have a discernible name
Link text (and alternate text for images, when used as links) that is discernible, unique, and focusable improves the navigation experience for screen reader users. Learn how to make links accessible.
Best practices
These items highlight common accessibility best practices.
`[user-scalable="no"]` is used in the `<meta name="viewport">` element or the `[maximum-scale]` attribute is less than 5.
Disabling zooming is problematic for users with low vision who rely on screen magnification to properly see the contents of a web page. Learn more about the viewport meta tag.
Navigation
These are opportunities to improve keyboard navigation in your application.
Heading elements are not in a sequentially-descending order
Properly ordered headings that do not skip levels convey the semantic structure of the page, making it easier to navigate and understand when using assistive technologies. Learn more about heading order.
