Beizi.biz Mobile Performance: 41/100
Quick overview:
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Reduce unused CSS
Potential savings of 561 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 serving legacy JavaScript to modern browsers
Potential savings of 52 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
Potential savings of 1,270 ms
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.
Reduce unused JavaScript
Potential savings of 1,144 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.
Minimize main-thread work
2.7 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
Efficiently encode images
Potential savings of 8 KiB
Optimized images load faster and consume less cellular data. Learn how to efficiently encode images.
Largest Contentful Paint element
14,580 ms
This is the largest contentful element painted within the viewport. Learn more about the Largest Contentful Paint element
Enable text compression
Potential savings of 1,738 KiB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn more about text compression.
Serve images in next-gen formats
Potential savings of 3,154 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.
Serve static assets with an efficient cache policy
35 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more about efficient cache policies.
Avoid enormous network payloads
Total size was 7,435 KiB
Large network payloads cost users real money and are highly correlated with long load times. Learn how to reduce payload sizes.
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
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`.
Defer offscreen images
Potential savings of 116 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.
Properly size images
Potential savings of 2,851 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().
Time to Interactive
20.8 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
440 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.
Beizi.biz Mobile SEO: 82/100
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.
Document does not have a meta description
Meta descriptions may be included in search results to concisely summarize page content. Learn more about the meta description.
Beizi.biz Mobile Best Practices: 62/100
Quick overview:
General
Missing source maps for large first-party JavaScript
Source maps translate minified code to the original source code. This helps developers debug in production. In addition, Lighthouse is able to provide further insights. Consider deploying source maps to take advantage of these benefits. Learn more about source maps.
Uses deprecated APIs
2 warnings found
Deprecated APIs will eventually be removed from the browser. Learn more about deprecated APIs.
Trust and Safety
Does not use HTTPS
32 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.
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.
Beizi.biz Mobile Accessibility: 74/100
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.
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.
ARIA
These are opportunities to improve the usage of ARIA in your application which may enhance the experience for users of assistive technology, like a screen reader.
`[aria-*]` attributes do not have valid values
Assistive technologies, like screen readers, can't interpret ARIA attributes with invalid values. Learn more about valid values for ARIA attributes.
Uses ARIA roles on incompatible elements
Many HTML elements can only be assigned certain ARIA roles. Using ARIA roles where they are not allowed can interfere with the accessibility of the web page. Learn more about ARIA roles.
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.
Elements with visible text labels do not have matching accessible names.
Visible text labels that do not match the accessible name can result in a confusing experience for screen reader users. Learn more about accessible names.
Tables and lists
These are opportunities to improve the experience of reading tabular or list data using assistive technology, like a screen reader.
Lists do not contain only `<li>` elements and script supporting elements (`<script>` and `<template>`).
Screen readers have a specific way of announcing lists. Ensuring proper list structure aids screen reader output. Learn more about proper list structure.
