Technical Analysis

Opportunities

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 15 KiB

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.

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: 450 ms

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: 150 ms

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: 1020 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

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.

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.

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.

Efficiently encode images

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

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.

Remove duplicate modules in JavaScript bundles

• Description: Remove large, duplicate JavaScript modules from bundles to reduce unnecessary bytes consumed by network activity.
• Potential Savings: Potential savings of 64 KiB

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.
• Potential Savings: Potential savings of 9 KiB

Avoid multiple page redirects

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

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.

Avoid large layout shifts

• Description: These are the largest layout shifts observed on the page. Each table item represents a single layout shift, and shows the element that shifted the most. Below each item are possible root causes that led to the layout shift. Some of these layout shifts may not be included in the CLS metric value due to windowing. Learn how to improve CLS
• Display Value: 2 layout shifts found

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.

• Description: Collects all available metrics.
• Numeric Value: 29336

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.

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.
