Quick overview:
Content Best Practices
Format your HTML in a way that enables crawlers to better understand your app’s content.
Document doesn't have a `<title>` element
The title gives screen reader users an overview of the page, and search engine users rely on it heavily to determine if a page is relevant to their search. Learn more about document titles.
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.
Crawling and Indexing
To appear in search results, crawlers need access to your app.
Page is blocked from indexing
Search engines are unable to include your pages in search results if they don't have permission to crawl them. Learn more about crawler directives.
Mobile Friendly
Make sure your pages are mobile friendly so users don’t have to pinch or zoom in order to read the content pages. Learn how to make pages mobile-friendly.
Tap targets are not sized appropriately
Interactive elements like buttons and links should be large enough (48x48px), or have enough space around them, to be easy enough to tap without overlapping onto other elements. Learn more about tap targets. Tap targets are too small because there's no viewport meta tag optimized for mobile screens
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.
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
89os65.cn Mobile Best Practices: 78/100
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.
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
89os65.cn Mobile PWA: 0/100
Quick overview:
PWA Optimized
Does not set a theme color for the address bar.
The browser address bar can be themed to match your site. Learn more about theming the address bar. Failures: No manifest was fetched,
No `<meta name="theme-color">` tag found.
Is not configured for a custom splash screen
A themed splash screen ensures a high-quality experience when users launch your app from their homescreens. Learn more about splash screens. Failures: No manifest was fetched.
Content is not sized correctly for the viewport
If the width of your app's content doesn't match the width of the viewport, your app might not be optimized for mobile screens. Learn how to size content for the viewport. The viewport size of 981px does not match the window size of 412px.
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
Manifest doesn't have a maskable icon
A maskable icon ensures that the image fills the entire shape without being letterboxed when installing the app on a device. Learn about maskable manifest icons. No manifest was fetched
Installable
Web app manifest or service worker do not meet the installability requirements
1 reason
Service worker is the technology that enables your app to use many Progressive Web App features, such as offline, add to homescreen, and push notifications. With proper service worker and manifest implementations, browsers can proactively prompt users to add your app to their homescreen, which can lead to higher engagement. Learn more about manifest installability requirements.
89os65.cn Mobile Accessibility: 55/100
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.
Document doesn't have a `<title>` element
The title gives screen reader users an overview of the page, and search engine users rely on it heavily to determine if a page is relevant to their search. Learn more about document titles.
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.
