Elinux.org Mobile Performance: 81/100
Quick overview:
Opportunities
These suggestions can help your page load faster. They don't directly affect the Performance score.
Avoid multiple page redirects. Potential savings of 1,110 ms
Redirects introduce additional delays before the page can be loaded. Learn more.
Enable text compression. Potential savings of 185 KiB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn more.
Remove unused JavaScript. Potential savings of 96 KiB
Remove unused JavaScript to reduce bytes consumed by network activity. Learn more.
Serve images in next-gen formats. Potential savings of 194 KiB
Image formats like JPEG 2000, JPEG XR, and WebP often provide better compression than PNG or JPEG, which means faster downloads and less data consumption. Learn more.
Eliminate render-blocking resources. Potential savings of 130 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles. Learn more.
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Avoid `document.write()`
For users on slow connections, external scripts dynamically injected via `document.write()` can delay page load by tens of seconds. Learn more.
Serve static assets with an efficient cache policy
71 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more.
Avoid long main-thread tasks
5 long tasks found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay. Learn more
Largest Contentful Paint element
1 element found
This is the largest contentful element painted within the viewport. Learn More
User Timing marks and measures
2 user timings
Consider instrumenting your app with the User Timing API to measure your app's real-world performance during key user experiences. Learn more.
Avoid chaining critical requests
2 chains found
The Critical Request Chains below show you what resources are loaded with a high priority. Consider reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load. Learn more.
Keep request counts low and transfer sizes small
75 requests • 679 KiB
To set budgets for the quantity and size of page resources, add a budget.json file. Learn more.
Avoid large layout shifts
2 elements found
These DOM elements contribute most to the CLS of the page.
Elinux.org Mobile SEO: 58/100
Quick overview:
Content Best Practices
Format your HTML in a way that enables crawlers to better understand your app’s content.
Document does not have a meta description
Meta descriptions may be included in search results to concisely summarize page content. Learn more.
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 More
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 more.
Does not have a `<meta name="viewport">` tag with `width` or `initial-scale`
Add a `<meta name="viewport">` tag to optimize your app for mobile screens. Learn more. No `<meta name="viewport">` tag found
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. Text is illegible because there's no viewport meta tag optimized for mobile screens.
Tap targets are not sized appropriately
Interactive elements like buttons and links should be large enough (48x48px), and have enough space around them, to be easy enough to tap without overlapping onto other elements. Learn more. Tap targets are too small because there's no viewport meta tag optimized for mobile screens
Elinux.org Mobile Best Practices: 77/100
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 servedover 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.
Includes front-end JavaScript libraries with known security vulnerabilities
3 vulnerabilities detected
Some third-party scripts may contain known security vulnerabilities that are easily identified and exploited by attackers. Learn more.
User Experience
Serves images with low resolution
Image natural dimensions should be proportional to the display size and the pixel ratio to maximize image clarity. Learn more.
Elinux.org Mobile Progressive Web App: 36/100
Quick overview:
Fast and reliable
Current page does not respond with a 200 when offline
If you're building a Progressive Web App, consider using a service worker so that your app can work offline. Learn more.
`start_url` does not respond with a 200 when offline
A service worker enables your web app to be reliable in unpredictable network conditions. Learn more. No usable web app manifest found on page.
Installable
Does not register a service worker that controls page and `start_url`
The 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. Learn more.
Web app manifest does not meet the installability requirements
Browsers can proactively prompt users to add your app to their homescreen, which can lead to higher engagement. Learn more. Failures: No manifest was fetched.
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 servedover 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.
PWA Optimized
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 more. No manifest was fetched
Does not have a `<meta name="viewport">` tag with `width` or `initial-scale`
Add a `<meta name="viewport">` tag to optimize your app for mobile screens. Learn more. No `<meta name="viewport">` tag found
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 more. The viewport size of 980px does not match the window size of 360px.
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. Failures: No manifest was fetched.
Does not set a theme color for the address bar.
The browser address bar can be themed to match your site. Learn more. Failures: No manifest was fetched,
No `<meta name="theme-color">` tag found.
Does not provide a valid `apple-touch-icon`
For ideal appearance on iOS when users add a progressive web app to the home screen, define an `apple-touch-icon`. It must point to a non-transparent 192px (or 180px) square PNG. Learn More.
Elinux.org Mobile Accessibility: 98/100
Quick overview:
Navigation
These are opportunities to improve keyboard navigation in your application.
Some elements have a `[tabindex]` value greater than 0
A value greater than 0 implies an explicit navigation ordering. Although technically valid, this often creates frustrating experiences for users who rely on assistive technologies. Learn more.
