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.
Use video formats for animated content
Potential savings of 2,620 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

18,480 ms
This is the largest contentful element painted within the viewport. Learn more about the Largest Contentful Paint element
Avoid large layout shifts
5 layout shifts found
These are the largest layout shifts observed on the page. Each table item represents a single layout shift, and shows the element that shifted the most. Below each item are possible root causes that led to the layout shift. Some of these layout shifts may not be included in the CLS metric value due to windowing. Learn how to improve CLS
Avoid enormous network payloads
Total size was 32,364 KiB
Large network payloads cost users real money and are highly correlated with long load times. Learn how to reduce payload sizes.

Potential savings of 19 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.
Avoid an excessive DOM size
4,748 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.
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().
Efficiently encode images
Potential savings of 3,263 KiB
Optimized images load faster and consume less cellular data. Learn how to efficiently encode images.
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.
Minify JavaScript
Potential savings of 4 KiB
Minifying JavaScript files can reduce payload sizes and script parse time. Learn how to minify JavaScript.
Serve static assets with an efficient cache policy
92 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more about efficient cache policies.
Serve images in next-gen formats
Potential savings of 8,577 KiB

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.
Defer offscreen images
Potential savings of 22,052 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.
Time to Interactive
19.7 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.

Nbshichuang.com 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

Nbshichuang.com Mobile Best Practices: 55/100
Quick overview:
User Experience
Displays images with incorrect aspect ratio
Image display dimensions should match natural aspect ratio. Learn more about image aspect ratio.
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 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.
General
Uses deprecated APIs
1 warning found
Deprecated APIs will eventually be removed from the browser. Learn more about deprecated APIs.
