Vn88.ren Test Results

Vn88.ren Mobile Performance: 90/100
Quick overview:
Render blocking requests
Est savings of 840 ms
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.
Use efficient cache lifetimes
Est savings of 28 KiB
A long cache lifetime can speed up repeat visits to your page. Learn more.
Network dependency tree
Avoid chaining critical requests by reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load.
Forced reflow
A forced reflow occurs when JavaScript queries geometric properties (such as offsetWidth) after styles have been invalidated by a change to the DOM state. This can result in poor performance. Learn more about forced reflows and possible mitigations.
Improve image delivery
Est savings of 2,646 KiB
Reducing the download time of images can improve the perceived load time of the page and LCP. Learn more about optimizing image size
Document request latency
Est savings of 340 ms
Your first network request is the most important. Reduce its latency by avoiding redirects, ensuring a fast server response, and enabling text compression.
Font display
Est savings of 360 ms
Consider setting font-display to swap or optional to ensure text is consistently visible. swap can be further optimized to mitigate layout shifts with font metric overrides.
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Eliminate render-blocking resources
Est savings of 390 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 multiple page redirects
Est savings of 630 ms
Redirects introduce additional delays before the page can be loaded. Learn how to avoid page redirects.
Largest Contentful Paint element
3,050 ms
This is the largest contentful element painted within the viewport. Learn more about the Largest Contentful Paint element
Properly size images
Est savings of 1,919 KiB
Serve images that are appropriately-sized to save cellular data and improve load time. Learn how to size images.
Reduce unused CSS
Est savings of 24 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.
Reduce unused JavaScript
Est savings of 139 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.
Avoid an excessive DOM size
1,058 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.
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
Avoid enormous network payloads
Total size was 3,831 KiB
Large network payloads cost users real money and are highly correlated with long load times. Learn how to reduce payload sizes.
Use video formats for animated content
Est savings of 771 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
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.
Efficiently encode images
Est savings of 6 KiB
Optimized images load faster and consume less cellular data. Learn how to efficiently encode images.
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.
Serve images in next-gen formats
Est savings of 18 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.

Vn88.ren Mobile SEO: 100/100
Quick overview:

Vn88.ren Mobile Best Practices: 79/100
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
Document doesn't use legible font sizes
27.1% legible text
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.
Vn88.ren Mobile Accessibility: 86/100
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.
Links do not have a discernible name
Link text (and alternate text for images, when used as links) that is discernible, unique, and focusable improves the navigation experience for screen reader users. Learn how to make links accessible.
Navigation
These are opportunities to improve keyboard navigation in your application.
Heading elements are not in a sequentially-descending order
Properly ordered headings that do not skip levels convey the semantic structure of the page, making it easier to navigate and understand when using assistive technologies. Learn more about heading order.
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.
