Technical Analysis

Opportunities

Efficiently encode images

• Description: Optimized images load faster and consume less cellular data. Learn how to efficiently encode images.
• Potential Savings: Potential savings of 69 KiB

Remove duplicate modules in JavaScript bundles

• Description: Remove large, duplicate JavaScript modules from bundles to reduce unnecessary bytes consumed by network activity.

Reduce unused JavaScript

• Description: Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity. Learn how to reduce unused JavaScript.
• Potential Savings: 80 ms

Eliminate render-blocking resources

• Description: 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.
• Potential Savings: 427 ms

Reduce unused CSS

• Description: 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.
• Potential Savings: Potential savings of 12 KiB

Reduce initial server response time

• Description: 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.
• Potential Savings: 835 ms

Enable text compression

• Description: Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn more about text compression.

Minify JavaScript

• Description: Minifying JavaScript files can reduce payload sizes and script parse time. Learn how to minify JavaScript.

Defer offscreen images

• Description: 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.

Preconnect to required origins

• Description: Consider adding preconnect or dns-prefetch resource hints to establish early connections to important third-party origins. Learn how to preconnect to required origins.

Serve images in next-gen formats

• Description: 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.
• Potential Savings: 120 ms

Avoid multiple page redirects

• Description: Redirects introduce additional delays before the page can be loaded. Learn how to avoid page redirects.
• Potential Savings: 230 ms

Use video formats for animated content

• Description: 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 about efficient video formats

Avoid serving legacy JavaScript to modern browsers

• Description: Polyfills and transforms enable legacy browsers to use new JavaScript features. However, many aren't necessary for modern browsers. For your bundled JavaScript, adopt a modern script deployment strategy using module/nomodule feature detection to reduce the amount of code shipped to modern browsers, while retaining support for legacy browsers. Learn how to serve modern JavaScript
• Potential Savings: Potential savings of 28 KiB

Properly size images

• Description: Serve images that are appropriately-sized to save cellular data and improve load time. Learn how to size images.
• Potential Savings: 80 ms

Minify CSS

• Description: Minifying CSS files can reduce network payload sizes. Learn how to minify CSS.

Preload Largest Contentful Paint image

• Description: If the LCP element is dynamically added to the page, you should preload the image in order to improve LCP. Learn more about preloading LCP elements.

Diagnostics

<video> elements contain a <track> element with [kind="captions"]

• Description: When a video provides a caption it is easier for deaf and hearing impaired users to access its information. Learn more about video captions.

Server Backend Latencies

• Description: Server latencies can impact web performance. If the server latency of an origin is high, it's an indication the server is overloaded or has poor backend performance. Learn more about server response time.
• Display Value: 50 ms
• Numeric Value: 53

Network Round Trip Times

• Description: Network round trip times (RTT) have a large impact on performance. If the RTT to an origin is high, it's an indication that servers closer to the user could improve performance. Learn more about the Round Trip Time.
• Display Value: 10 ms
• Numeric Value: 5.372099999999999

Mitigate clickjacking with XFO or CSP

• Description: The X-Frame-Options (XFO) header or the frame-ancestors directive in the Content-Security-Policy (CSP) header control where a page can be embedded. These can mitigate clickjacking attacks by blocking some or all sites from embedding the page. Learn more about mitigating clickjacking.

Network Requests

• Description: Lists the network requests that were made during page load.

Avoid non-composited animations

• Description: Animations which are not composited can be janky and increase CLS. Learn how to avoid non-composited animations
• Display Value: 12 animated elements found

Diagnostics

• Description: Collection of useful page vitals.

Metrics

• Description: Collects all available metrics.
• Numeric Value: 2607

Detected JavaScript libraries

• Description: All front-end JavaScript libraries detected on the page. Learn more about this JavaScript library detection diagnostic audit.

Tasks

• Description: Lists the toplevel main thread tasks that executed during page load.

Avoid chaining critical requests

• Description: 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 how to avoid chaining critical requests.
• Display Value: 62 chains found

Final Screenshot

• Description: The last screenshot captured of the pageload.

Minimize third-party usage

• Description: 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.
• Display Value: Third-party code blocked the main thread for 0 ms

Script Treemap Data

• Description: Used for treemap app

Screenshot Thumbnails

• Description: This is what the load of your site looked like.

Use a strong HSTS policy

• Description: Deployment of the HSTS header significantly reduces the risk of downgrading HTTP connections and eavesdropping attacks. A rollout in stages, starting with a low max-age is recommended. Learn more about using a strong HSTS policy.

Ensure proper origin isolation with COOP

• Description: The Cross-Origin-Opener-Policy (COOP) can be used to isolate the top-level window from other documents such as pop-ups. Learn more about deploying the COOP header.

Resources Summary

• Description: Aggregates all network requests and groups them by type

Ensure CSP is effective against XSS attacks

• Description: A strong Content Security Policy (CSP) significantly reduces the risk of cross-site scripting (XSS) attacks. Learn how to use a CSP to prevent XSS
