Upv.es Test Results
Upv.es Mobile Performance: 64/100
Quick overview:
LCP request discovery
Optimize LCP by making the LCP image discoverable from the HTML immediately, and avoiding lazy-loading
Forced reflow
Many APIs, typically reading layout geometry, force the rendering engine to pause script execution in order to calculate the style and layout. Learn more about forced reflow and its mitigations.
Improve image delivery
Est savings of 1,210 KiB
Reducing the download time of images can improve the perceived load time of the page and LCP. Learn more about optimizing image size
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.
Use efficient cache lifetimes
Est savings of 7,491 KiB
A long cache lifetime can speed up repeat visits to your page. Learn more.
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.
Time to Interactive
12.7 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.
Document request latency
Est savings of 76 KiB
Your first network request is the most important. Reduce its latency by avoiding redirects, ensuring a fast server response, and enabling text compression.
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Efficiently encode images
Est savings of 443 KiB
Optimized images load faster and consume less cellular data. Learn how to efficiently encode images.
Serve images in next-gen formats
Est savings of 922 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.
Largest Contentful Paint element
12,600 ms
This is the largest contentful element painted within the viewport. Learn more about the Largest Contentful Paint element
Enable text compression
Est savings of 229 KiB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn more about text compression.
Defer offscreen images
Est savings of 521 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
Est savings of 1,770 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.
Reduce unused CSS
Est savings of 27 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 70 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.
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
Minify JavaScript
Est savings of 5 KiB
Minifying JavaScript files can reduce payload sizes and script parse time. Learn how to minify JavaScript.
Avoid enormous network payloads
Total size was 12,966 KiB
Large network payloads cost users real money and are highly correlated with long load times. Learn how to reduce payload sizes.
Properly size images
Est savings of 88 KiB
Serve images that are appropriately-sized to save cellular data and improve load time. Learn how to size images.
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.
Upv.es Mobile SEO: 92/100
Quick overview:
Content Best Practices
Format your HTML in a way that enables crawlers to better understand your app’s content.
Links do not have descriptive text
10 links found
Descriptive link text helps search engines understand your content. Learn how to make links more accessible.
Upv.es Mobile Best Practices: 79/100
Quick overview:
Trust and Safety
Does not redirect HTTP traffic to HTTPS
Make sure that you redirect all HTTP traffic to HTTPS in order to enable secure web features for all your users. Learn more.
Does not use HTTPS
34 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.
Upv.es Mobile Accessibility: 90/100
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.
Form elements do not have associated labels
Labels ensure that form controls are announced properly by assistive technologies, like screen readers. Learn more about form element labels.
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.
