Technical Analysis

Opportunities

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: 378 ms

Avoid multiple page redirects

• Description: Redirects introduce additional delays before the page can be loaded. Learn how to avoid page redirects.
• Potential Savings: 1542.540344505366 ms

Minify JavaScript

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

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: 250 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.

Initial server response time was short

• 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: 128 ms

Remove duplicate modules in JavaScript bundles

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

Minify CSS

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

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: Potential savings of 13 KiB

Efficiently encode images

• Description: Optimized images load faster and consume less cellular data. Learn how to efficiently encode images.

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: Potential savings of 10 KiB

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.

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.

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: 620 ms

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 0 KiB

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.

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

Diagnostics

Detected JavaScript libraries

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

Network Requests

• Description: Lists the network requests that were made 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: 2 chains found

Avoid long main-thread tasks

• Description: Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay. Learn how to avoid long main-thread tasks
• Display Value: 20 long tasks found

Final Screenshot

• Description: The last screenshot captured of the pageload.

Script Treemap Data

• Description: Used for treemap app

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.

Diagnostics

• Description: Collection of useful page vitals.

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.

Tasks

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

Resources Summary

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

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: 3 animated elements found

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: 9.098459999999998

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.

Identical links have the same purpose.

• Description: Links with the same destination should have the same description, to help users understand the link's purpose and decide whether to follow it. Learn more about identical links.
