Opportunities

These suggestions can help your page load faster. They don't directly affect the Performance score.

Preload key requests. Potential savings of 4,230 ms

Consider using `<link rel=preload>` to prioritize fetching resources that are currently requested later in page load. Learn more.

Remove unused JavaScript. Potential savings of 441 KB

Remove unused JavaScript to reduce bytes consumed by network activity. Learn more.

Enable text compression. Potential savings of 186 KB

Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn more.

Avoid multiple page redirects. Potential savings of 1,260 ms

Redirects introduce additional delays before the page can be loaded. Learn more.

Serve images in next-gen formats. Potential savings of 147 KB

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 930 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.

Remove unused CSS. Potential savings of 61 KB

Remove dead rules from stylesheets and defer the loading of CSS not used for above-the-fold content to reduce unnecessary bytes consumed by network activity. 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.

Consider marking your touch and wheel event listeners as `passive` to improve your page's scroll performance. Learn more.

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.

Reduce the impact of third-party code

Third-party code blocked the main thread for 660 ms

Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading. Learn more.

Serve static assets with an efficient cache policy

47 resources found

A long cache lifetime can speed up repeat visits to your page. Learn more.

Minimize main-thread work

9.3 s

Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this. Learn more

4.8 s

Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this. Learn more.

Avoid an excessive DOM size

1,005 elements

A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows. Learn more.

Avoids enormous network payloads

Total size was 2,626 KB

Large network payloads cost users real money and are highly correlated with long load times. Learn more.

Avoid large layout shifts

No elements found

These DOM elements contribute most to the CLS of the page.

Avoid chaining critical requests

3 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

125 requests • 2,626 KB

To set budgets for the quantity and size of page resources, add a budget.json file. Learn more.

Sun.de Mobile Accessibility: 82/100

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.

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 more.

Tables and lists

These are opportunities to 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.

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.

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.

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.
