51dssd.com Test Results

51dssd.com Mobile Performance: 76/100
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 30 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.
Eliminate render-blocking resources
Potential savings of 890 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.
Largest Contentful Paint element
3,640 ms
This is the largest contentful element painted within the viewport. Learn more about the Largest Contentful Paint element
Avoid multiple page redirects
Potential savings of 1,260 ms
Redirects introduce additional delays before the page can be loaded. Learn how to avoid page redirects.
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
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.
Avoid an excessive DOM size
872 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.
Minify JavaScript
Potential savings of 4 KiB
Minifying JavaScript files can reduce payload sizes and script parse time. Learn how to minify JavaScript.
Serve static assets with an efficient cache policy
50 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
Potential savings of 882 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.
Efficiently encode images
Potential savings of 527 KiB
Optimized images load faster and consume less cellular data. Learn how to efficiently encode images.
Minify CSS
Potential savings of 5 KiB
Minifying CSS files can reduce network payload sizes. Learn how to minify CSS.
Insights
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.
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.
LCP request discovery
Optimize LCP by making the LCP image discoverable from the HTML immediately, and avoiding lazy-loading
Time to Interactive
3.6 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.

51dssd.com Mobile Best Practices: 79/100
Quick overview:
Trust and Safety
Does not use HTTPS
2 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.
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
51dssd.com Mobile Accessibility: 58/100
Quick overview:
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.
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.
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.
Best practices
These items highlight common accessibility best practices.
Touch targets do not have sufficient size or spacing.
Touch targets with sufficient size and spacing help users who may have difficulty targeting small controls to activate the targets. Learn more about touch targets.
`[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.
