Shift8web.ca Test Results
Shift8web.ca Mobile Performance: 8/100
Quick overview:
Opportunities
These suggestions can help your page load faster. They don't directly affect the Performance score.
Use video formats for animated content. Potential savings of 4,955 KiB
Large GIFs are inefficient for delivering animated content. Consider using MPEG4/WebM videos for animations and PNG/WebP for static images instead of GIF to save network bytes. Learn more
Eliminate render-blocking resources. Potential savings of 4,370 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 JavaScript. Potential savings of 327 KiB
Remove unused JavaScript to reduce bytes consumed by network activity. Learn more.
Remove unused CSS. Potential savings of 200 KiB
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.
Serve images in next-gen formats. Potential savings of 291 KiB
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.
Preload key requests. Potential savings of 240 ms
Consider using `<link rel=preload>` to prioritize fetching resources that are currently requested later in page load. Learn more.
Minify CSS. Potential savings of 5 KiB
Minifying CSS files can reduce network payload sizes. Learn more.
Enable text compression. Potential savings of 7 KiB
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn more.
Minify JavaScript. Potential savings of 13 KiB
Minifying JavaScript files can reduce payload sizes and script parse time. Learn more.
Efficiently encode images. Potential savings of 57 KiB
Optimized images load faster and consume less cellular data. Learn more.
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
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.
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.
Reduce the impact of third-party code
Third-party code blocked the main thread for 2,710 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.
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.
Minimize main-thread work
12.8 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this. Learn more
Avoid enormous network payloads
Total size was 8,186 KiB
Large network payloads cost users real money and are highly correlated with long load times. Learn more.
Serve static assets with an efficient cache policy
99 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more.
Reduce JavaScript execution time
6.6 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this. Learn more.
Avoid long main-thread tasks
20 long tasks found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay. Learn more
Largest Contentful Paint element
1 element found
This is the largest contentful element painted within the viewport. Learn More
Keep request counts low and transfer sizes small
128 requests • 8,186 KiB
To set budgets for the quantity and size of page resources, add a budget.json file. Learn more.
Avoid chaining critical requests
61 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.

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 servedover 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.
Includes front-end JavaScript libraries with known security vulnerabilities
5 vulnerabilities detected
Some third-party scripts may contain known security vulnerabilities that are easily identified and exploited by attackers. Learn more.
User Experience
Serves images with low resolution
Image natural dimensions should be proportional to the display size and the pixel ratio to maximize image clarity. Learn more.
Shift8web.ca Mobile Progressive Web App: 25/100
Quick overview:
Fast and reliable
Page load is not fast enough on mobile networks
Interactive at 34.2 s
A fast page load over a cellular network ensures a good mobile user experience. Learn more. Your page loads too slowly and is not interactive within 10 seconds. Look at the opportunities and diagnostics in the "Performance" section to learn how to improve.
`start_url` does not respond with a 200 when offline
A service worker enables your web app to be reliable in unpredictable network conditions. Learn more. No usable web app manifest found on page.
Current page does not respond with a 200 when offline
If you're building a Progressive Web App, consider using a service worker so that your app can work offline. Learn more.
Installable
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 servedover 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.
Web app manifest does not meet the installability requirements
Browsers can proactively prompt users to add your app to their homescreen, which can lead to higher engagement. Learn more. Failures: No manifest was fetched.
Does not register a service worker that controls page and `start_url`
The service worker is the technology that enables your app to use many Progressive Web App features, such as offline, add to homescreen, and push notifications. Learn more.
