Quick overview:
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Efficiently encode images
Potential savings of 711 KiB
Optimized images load faster and consume less cellular data. Learn how to efficiently encode images.
Avoid multiple page redirects
Potential savings of 1,590 ms
Redirects introduce additional delays before the page can be loaded. Learn how to avoid page redirects.
Reduce unused JavaScript
Potential savings of 160 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.
Reduce JavaScript execution time
3.0 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this. Learn how to reduce Javascript execution time.
Avoid an excessive DOM size
4,303 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.
Minimize main-thread work
4.7 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this. Learn how to minimize main-thread work
Reduce unused CSS
Potential savings of 87 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.
Serve images in next-gen formats
Potential savings of 1,533 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.
Defer offscreen images
Potential savings of 17 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive. Learn how to defer offscreen images.
Eliminate render-blocking resources
Potential savings of 3,330 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.
Minify JavaScript
Potential savings of 64 KiB
Minifying JavaScript files can reduce payload sizes and script parse time. Learn how to minify JavaScript.
Properly size images
Potential savings of 1,006 KiB
Serve images that are appropriately-sized to save cellular data and improve load time. Learn how to size images.
Largest Contentful Paint element
16,080 ms
This is the largest contentful element painted within the viewport. Learn more about the Largest Contentful Paint element
Serve static assets with an efficient cache policy
37 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more about efficient cache policies.
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 about `font-display`.
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 2,702 KiB
Large network payloads cost users real money and are highly correlated with long load times. Learn how to reduce payload sizes.
Avoid serving legacy JavaScript to modern browsers
Potential savings of 0 KiB
Polyfills and transforms enable legacy browsers to use new JavaScript features. However, many aren't necessary for modern browsers. For your bundled JavaScript, adopt a modern script deployment strategy using module/nomodule feature detection to reduce the amount of code shipped to modern browsers, while retaining support for legacy browsers. Learn how to use modern JavaScript
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.
Max Potential First Input Delay
1,830 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task. Learn more about the Maximum Potential First Input Delay metric.
Time to Interactive
15.6 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.
First Meaningful Paint
6.1 s
First Meaningful Paint measures when the primary content of a page is visible. Learn more about the First Meaningful Paint metric.
Rv.de Mobile SEO: 92/100
Quick overview:
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 how to make links crawlable
Rv.de Mobile Best Practices: 83/100
Quick overview:
Trust and Safety
Does not use HTTPS
3 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.
Rv.de Mobile Accessibility: 86/100
Quick overview:
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.
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.
Elements with visible text labels do not have matching accessible names.
Visible text labels that do not match the accessible name can result in a confusing experience for screen reader users. Learn more about accessible names.
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 about the `tabindex` attribute.
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.
