Qingsheshuo.com Mobile Performance: 65/100
Quick overview:
Insights
Layout shift culprits
Layout shifts occur when elements move absent any user interaction. Investigate the causes of layout shifts, such as elements being added, removed, or their fonts changing as the page loads.
Document request latency
Your first network request is the most important. Reduce its latency by avoiding redirects, ensuring a fast server response, and enabling text compression.
Improve image delivery
Reducing the download time of images can improve the perceived load time of the page and LCP. Learn more about optimizing image size
Render blocking requests
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.
Optimize viewport for mobile
Tap interactions may be delayed by up to 300 ms if the viewport is not optimized for mobile.
Third parties
Third party code can significantly impact load performance. Reduce and defer loading of third party code to prioritize your page's content.
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Defer offscreen images
Potential savings of 113 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.
Avoid multiple page redirects
Potential savings of 630 ms
Redirects introduce additional delays before the page can be loaded. Learn how to avoid page redirects.
Largest Contentful Paint element
3,260 ms
This is the largest contentful element painted within the viewport. Learn more about the Largest Contentful Paint element
Avoid large layout shifts
1 layout shift 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
Serve images in next-gen formats
Potential savings of 193 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.
Enable text compression
Potential 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.
Serve static assets with an efficient cache policy
3 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more about efficient cache policies.
Reduce unused JavaScript
Potential savings of 236 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.
Eliminate render-blocking resources
Potential savings of 0 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.
Avoid serving legacy JavaScript to modern browsers
Potential savings of 33 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 serve modern JavaScript
Reduce unused CSS
Potential savings of 33 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.
Properly size images
Potential savings of 8 KiB
Serve images that are appropriately-sized to save cellular data and improve load time. Learn how to size images.
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().
Max Potential First Input Delay
140 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.
Time to Interactive
3.3 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.

Qingsheshuo.com Mobile SEO: 92/100
Quick overview:
Crawling and Indexing
To appear in search results, crawlers need access to your app.
robots.txt is not valid
4 errors found

Qingsheshuo.com Mobile Best Practices: 72/100
Quick overview:
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
Displays images with incorrect aspect ratio
Image display dimensions should match natural aspect ratio. Learn more about image aspect ratio.
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
Browser Compatibility
Page lacks the HTML doctype, thus triggering quirks-mode
Specifying a doctype prevents the browser from switching to quirks-mode. Learn more about the doctype declaration. Document must contain a doctype
Qingsheshuo.com Mobile Accessibility: 50/100
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.
`<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.
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.
Internationalization and localization
These are opportunities to improve the interpretation of your content by users in different locales.
`<html>` element does not have a `[lang]` attribute
If a page doesn't specify a `lang` attribute, a screen reader assumes that the page is in the default language that the user chose when setting up the screen reader. If the page isn't actually in the default language, then the screen reader might not announce the page's text correctly. Learn more about the `lang` attribute.
