Pttcnetwork.org Test Results
Pttcnetwork.org Mobile Performance: 58/100
Quick overview:
Max Potential First Input Delay
940 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
11.5 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
3.3 s
First Meaningful Paint measures when the primary content of a page is visible. Learn more about the First Meaningful Paint metric.
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Minimize main-thread work
6.1 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
Eliminate render-blocking resources
Potential savings of 150 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
Reduce initial server response time
Root document took 1,560 ms
Keep the server response time for the main document short because all other requests depend on it. Learn more about the Time to First Byte metric.
Reduce unused CSS
Potential savings of 23 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 JavaScript execution time
2.4 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.
Reduce the impact of third-party code
Third-party code blocked the main thread for 2,450 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 how to minimize third-party impact.
Reduce unused JavaScript
Potential savings of 140 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.
Avoid multiple page redirects
Potential savings of 630 ms
Redirects introduce additional delays before the page can be loaded. Learn how to avoid page redirects.
Remove duplicate modules in JavaScript bundles
Potential savings of 30 KiB
Remove large, duplicate JavaScript modules from bundles to reduce unnecessary bytes consumed by network activity.
Defer offscreen images
Potential savings of 1,248 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.
Avoid enormous network payloads
Total size was 3,075 KiB
Large network payloads cost users real money and are highly correlated with long load times. Learn how to reduce payload sizes.
Minify JavaScript
Potential savings of 6 KiB
Minifying JavaScript files can reduce payload sizes and script parse time. Learn how to minify JavaScript.
Serve images in next-gen formats
Potential savings of 1,944 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.
Serve static assets with an efficient cache policy
31 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more about efficient cache policies.
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.
Efficiently encode images
Potential savings of 23 KiB
Optimized images load faster and consume less cellular data. Learn how to efficiently encode images.
Avoid an excessive DOM size
856 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.
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
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`.
Pttcnetwork.org 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
8 links found
Descriptive link text helps search engines understand your content. Learn how to make links more accessible.
Pttcnetwork.org Mobile Best Practices: 83/100
Quick overview:
Trust and Safety
Does not use HTTPS
1 insecure request 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.
Pttcnetwork.org 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.
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.
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-hidden="true"]` elements contain focusable descendents
Focusable descendents within an `aria-hidden="true"]` element prevent those interactive elements from being available to users of assistive technologies like screen readers. [Learn how `aria-hidden` affects focusable elements.
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.
