1,747 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows. Learn how to avoid an excessive DOM size.
Eliminate render-blocking resources
Potential savings of 6,950 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.
Reduce the impact of third-party code
Third-party code blocked the main thread for 2,080 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. Learn how to minimize third-party impact.
Reduce unused CSS
Potential savings of 122 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity. Learn how to reduce unused CSS.

Potential savings of 576 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.
Serve images in next-gen formats
Potential savings of 726 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.
Reduce initial server response time
Root document took 670 ms
Keep the server response time for the main document short because all other requests depend on it. Learn more about the Time to First Byte metric.
Avoid enormous network payloads
Total size was 3,530 KiB
Large network payloads cost users real money and are highly correlated with long load times. Learn how to reduce payload sizes.
Ensure text remains visible during webfont load
Leverage the `font-display` CSS feature to ensure text is user-visible while webfonts are loading. Learn more about `font-display`.
Avoid serving legacy JavaScript to modern browsers
Potential savings of 53 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. Learn how to use modern JavaScript
Preload Largest Contentful Paint image
If the LCP element is dynamically added to the page, you should preload the image in order to improve LCP. Learn more about preloading LCP elements.
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
Enable text compression
Potential savings of 93 KiB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn more about text compression.
Defer offscreen images
Potential savings of 89 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive. Learn how to defer offscreen images.

Zjstkj.cn Mobile SEO: 83/100
Quick overview:
Content Best Practices
Format your HTML in a way that enables crawlers to better understand your app’s content.
Image elements do not have `[alt]` attributes
Informative elements should aim for short, descriptive alternate text. Decorative elements can be ignored with an empty alt attribute. Learn more about the `alt` attribute.
Crawling and Indexing
To appear in search results, crawlers need access to your app.
Links are not crawlable
Search engines may use `href` attributes on links to crawl websites. Ensure that the `href` attribute of anchor elements links to an appropriate destination, so more pages of the site can be discovered. Learn how to make links crawlable
Zjstkj.cn Mobile Best Practices: 48/100
Quick overview:
General
Uses deprecated APIs
2 warnings found
Deprecated APIs will eventually be removed from the browser. Learn more about deprecated APIs.
User Experience
Document doesn't use legible font sizes
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. Learn more about legible font sizes. Text is illegible because there's no viewport meta tag optimized for mobile screens.
Displays images with incorrect aspect ratio
Image display dimensions should match natural aspect ratio. Learn more about image aspect ratio.
Does not have a `<meta name="viewport">` tag with `width` or `initial-scale`
A `<meta name="viewport">` not only optimizes your app for mobile screen sizes, but also prevents a 300 millisecond delay to user input. Learn more about using the viewport meta tag. No `<meta name="viewport">` tag found
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.
Trust and Safety
Does not redirect HTTP traffic to HTTPS
Make sure that you redirect all HTTP traffic to HTTPS in order to enable secure web features for all your users. Learn more.
Does not use HTTPS
99 insecure requests 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.
Zjstkj.cn Mobile Accessibility: 69/100
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.
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.
Image elements do not have `[alt]` attributes
Informative elements should aim for short, descriptive alternate text. Decorative elements can be ignored with an empty alt attribute. Learn more about the `alt` attribute.
Contrast
These are opportunities to improve the legibility of your content.
Background and foreground colors do not have a sufficient contrast ratio.
Low-contrast text is difficult or impossible for many users to read. Learn how to provide sufficient color contrast.
