Tjwenfa.com Mobile Performance: 63/100
Quick overview:
Insights
LCP request discovery
Optimize LCP by making the LCP image discoverable from the HTML immediately, and avoiding lazy-loading
Third parties
Third party code can significantly impact load performance. Reduce and defer loading of third party code to prioritize your page's content.
Layout shift culprits
Layout shifts occur when elements move absent any user interaction. Investigate the causes of layout shifts, such as elements being added, removed, or their fonts changing as the page loads.
Optimize viewport for mobile
Tap interactions may be delayed by up to 300 ms if the viewport is not optimized for mobile.
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.
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
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.
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Reduce unused CSS
Potential savings of 236 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.
Minify CSS
Potential savings of 20 KiB
Minifying CSS files can reduce network payload sizes. Learn how to minify CSS.
Enable text compression
Potential savings of 458 KiB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn more about text compression.
Largest Contentful Paint element
7,850 ms
This is the largest contentful element painted within the viewport. Learn more about the Largest Contentful Paint element
Reduce unused JavaScript
Potential savings of 208 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.
Eliminate render-blocking resources
Potential savings of 3,490 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.
Serve images in next-gen formats
Potential savings of 290 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.
Minify JavaScript
Potential savings of 5 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
51 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`.
Properly size images
Potential savings of 185 KiB
Serve images that are appropriately-sized to save cellular data and improve load time. Learn how to size images.
Efficiently encode images
Potential savings of 16 KiB
Optimized images load faster and consume less cellular data. Learn how to efficiently encode images.
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
Time to Interactive
8.0 s

Quick overview:
Trust and Safety
Does not use HTTPS
52 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.
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.
Tjwenfa.com Mobile Accessibility: 84/100
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 how to make links accessible.
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.
