Opportunities
These suggestions can help your page load faster. They don't directly affect the Performance score.
Defer offscreen images. Potential savings of 14,117 KB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive. Learn more.
Serve images in next-gen formats. Potential savings of 12,314 KB
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.
Efficiently encode images. Potential savings of 9,089 KB
Optimized images load faster and consume less cellular data. Learn more.
Properly size images. Potential savings of 1,700 KB
Serve images that are appropriately-sized to save cellular data and improve load time. Learn more.
Eliminate render-blocking resources. Potential savings of 840 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.
Reduce server response times (TTFB). Root document took 1,220 ms
Time To First Byte identifies the time at which your server sends a response. Learn more.
Minify JavaScript. Potential savings of 31 KB
Minifying JavaScript files can reduce payload sizes and script parse time. Learn more.
Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Reduce the impact of third-party code
Third-party code blocked the main thread for 790 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.
Avoid enormous network payloads
Total size was 18,019 KB
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
55 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more.
Minimize main-thread work
5.4 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this. Learn more
Reduce JavaScript execution time
2.9 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this. Learn more.
Avoid an excessive DOM size
948 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows. Learn more.
Keep request counts low and transfer sizes small
77 requests • 18,023 KB
To set budgets for the quantity and size of page resources, add a budget.json file. Learn more.
User Timing marks and measures
1 user timing
Consider instrumenting your app with the User Timing API to measure your app's real-world performance during key user experiences. Learn more.
Avoid chaining critical requests
14 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.
Butterfly.org.au Mobile SEO: 99/100
Quick overview:
Mobile Friendly
Make sure your pages are mobile friendly so users don’t have to pinch or zoom in order to read the content pages. Learn more.
Tap targets are not sized appropriately
90% appropriately sized tap targets
Interactive elements like buttons and links should be large enough (48x48px), and have enough space around them, to be easy enough to tap without overlapping onto other elements. Learn more.
Butterfly.org.au Mobile Best Practices: 69/100
Quick overview:
Does not use HTTPS
49 insecure requests found
All sites should be protected with HTTPS, even ones that don't handle sensitive data. 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
1 vulnerability detected
Some third-party scripts may contain known security vulnerabilities that are easily identified and exploited by attackers. Learn more.
Links to cross-origin destinations are unsafe
Add `rel="noopener"` or `rel="noreferrer"` to any external links to improve performance and prevent security vulnerabilities. Learn more.
Browser errors were logged to the console
Errors logged to the console indicate unresolved problems. They can come from network request failures and other browser concerns. Learn more
Butterfly.org.au Mobile Progressive Web App: 19/100
Quick overview:
PWA Optimized
Does not set a theme color for the address bar.
The browser address bar can be themed to match your site. Learn more. Failures: No manifest was fetched,
No `<meta name="theme-color">` tag found.
Is not configured for a custom splash screen
A themed splash screen ensures a high-quality experience when users launch your app from their homescreens. Learn more. Failures: No manifest was fetched.
Does not redirect HTTP traffic to HTTPS
If you've already set up HTTPS, make sure that you redirect all HTTP traffic to HTTPS in order to enable secure web features for all your users. Learn more.
Fast and reliable
Page load is not fast enough on mobile networks
Interactive at 46.3 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
49 insecure requests found
All sites should be protected with HTTPS, even ones that don't handle sensitive data. 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.
Butterfly.org.au 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.
Buttons do not have an accessible name
When a button doesn't have an accessible name, screen readers announce it as "button", making it unusable for users who rely on screen readers. Learn more.
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 more.
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 more.
