Speed
Load time101665 ms
Also known as the document complete time, it’s the time from the initial request until the browser load event. It can vary based on server location, device, browser, and third-party apps. Learn more
Page load is fast enough on 3G
A fast page load over a 3G network ensures a good mobile user experience. Learn more
First byte1782 ms
The time from the initial request to the first byte of the response. Learn more
First meaningful paint1451 ms
First meaningful paint measures when the primary content of a page is visible. It's essentially the paint after which the biggest above-the-fold layout change has happened, and web fonts have loaded. Learn more
Estimated Input Latency16 ms (target < 50 ms)
The score above is an estimate of how long your app takes to respond to user input, in milliseconds. There is a 90% probability that a user encounters this amount of latency, or less. 10% of the time a user can expect additional latency. If your score is higher than Lighthouse's target score (< 50 ms), users may perceive your app as laggy. Learn more
Uses persistent connections (keep alive)Score: 100%
Closing connections are a missed opportunity for performance enhancement: additional round-trips between the user and the server to initiate a connection is redundant and time-consuming. Keep-Alive measures the effectiveness of connection reuse. The purpose of this grade is to evaluate the extent to which requests are inefficiently reopening connections. Learn more
First interactive (beta - experimental)4050 ms
The first point at which necessary scripts of the page have loaded and the CPU is idle enough to handle most user input (with the possibility of slow responses as more content loads). Learn more
Consistently Interactive (beta - experimental)Not applicable
The point at which most network resources have finished loading and the CPU is idle for a prolonged period. Consistently Interactive requires a minimum of 5 seconds of both main thread idle and network idle. In other words, the point where the page is complete and will respond quickly to user input. Learn more
Page weight
Uses compression (gzip, zopfli, deflate, brotli)Score: 98%
This rule triggers when detecting that compressible resources were served without gzip compression. Learn more
Uses a CDN for all static assetsScore: 24%
Each request for a piece of content to the web server has to travel from the user's browser all the way to the server and back. A content delivery network (CDN) is a system for distributing resources to servers geographically closer to users. Main benefit of this is that the round-trip time is faster. The passing grade for using a CDN effectively is to have at least 80% of static resources served from a CDN. Learn more
Leverage browser caching1
Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network. Learn more
Minify CSS
Minification refers to the process of removing unnecessary or redundant data in order to reduce file size without affecting how the resource is processed by the browser - e.g. code comments and formatting, removing unused code, using shorter variable and function names, and so on. Learn more
Minify HTML
Minification refers to the process of removing unnecessary or redundant data in order to reduce file size without affecting how the resource is processed by the browser - e.g. code comments and formatting, removing unused code, using shorter variable and function names, and so on. Learn more

Avoids an excessive DOM size516 nodes
Number of elements in the document. Browser engineers recommend pages contain fewer than ~1,500 DOM nodes. The sweet spot is a tree depth < 32 elements and fewer than 60 children/parent element. A large DOM can increase memory usage, cause longer style calculations, and produce costly layout reflows. Learn more
-
Total DOM Nodes516target < 1,500 nodes
-
DOM Depth17target < 32
-
Maximum Children35target < 60 nodes
Compressed Images
The image compression check just looks at photo images and makes sure the quality isn't set too high. Images can usually be compressed pretty substantially without any noticeable reduction in visual quality. Learn more
Uses Progressive JPEGsScore: 99 %
A progressive JPEG is image created using the JPEG suite of compression algorithms that will 'fade in' in successive waves of lines until the entire image has completely arrived. They show the entire image right away, looking slightly pixelated until the image data is fully loaded. Learn more
Properly Sized ImagesPotential savings of 106 KB (~570 ms)
Serve images that are appropriately-sized to save cellular data and improve load time. Learn more
Offscreen imagesPotential savings of 2,626 KB (~14,100 ms)
Consider lazy-loading offscreen images to improve page load speed and time to interactive. Learn more
First impression
Eliminates render-blocking JavaScript and CSS in above-the-fold content
This rule triggers when detecting that your HTML references a blocking external resource / file in the above-the-fold portion of your page. Learn more about JS - Learn more about CSS
Prioritizes visible content
This rule triggers when detecting that additional network round trips are required to render the above-the-fold content of the page. Learn more
Improves server response time
This rule triggers when detecting that your server response time is above 200 ms. Server response time measures how long it takes to load the necessary HTML to begin rendering the page from your server, subtracting out the network latency between Google and your server. Learn more
Avoids landing page redirects
Redirects trigger an additional HTTP request-response cycle and delay page rendering. In the best case, each redirect will add a single round trip (HTTP request-response), and in the worst it may result in multiple additional roundtrips to perform the DNS lookup, TCP handshake, and TLS negotiation in addition to the additional HTTP request-response cycle. As a result, you should minimize use of redirects to improve site performance. Learn more
Usability 100/100
Clicking logo always leads you to homepage.
Make it easy to get back to the homepage. Use your logo as a navigation button to return to the homepage.
Key CTAs are visible on the homepage.
Keep menus short, visible and sweet.
No ending trailing paths.
Always provide navigation options on footers and/or fixed header.
Suports multi-device experiences.Not applicable
Use wishlists/favouriting/saved baskets; social sharing; email; to facilitate seamless movement between devices or mobile platforms.
For category pages/search result with lots of products, make sure lazy-loading or pagination are used.
Load images asynchronously -- after the above-the-fold content is fully loaded, or conditionally, only when they appear in the browser’s viewport.
Possible to swipe to see more images or tap to enlarge them.
Allow for mobile gestures like swipe or tap to enlarge images, graphics and other contents, keeping good quality and focus.
Streamlines forms information entry.
Minimize the number of fields and autofill information wherever possible. Implement correct input types in fields, i.e. input type = email, number, etc. Make use of tabIndex to iterate through fields with the keyboard.
Forms error warnings.
Users are notified immediately when mistakes are made in a field, and guidance is provided on how to fix it.
Makes site search visible and user-friendly.Not applicable
Place your site search near the top of your pages, via an open text field or clear label. Offer filters to help users get what they need from search or group results per categories. Auto-complete is available in on-site search.
Keeps your user in a single browser window.
Switching between windows on a smartphone can be troublesome, and raises the risk that visitors might not find their way back to your site. Try to keep users in one place by avoiding calls-to-action that launch new windows.

Responds 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
Uses HTTPS
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
Redirects HTTP traffic to HTTPS
If you've already set up HTTPS, make sure that you redirect all HTTP traffic to HTTPS. Learn more
Uses HTTP/2 for its own resources24 requests were not handled over HTTP/2
HTTP/2 offers many benefits over HTTP/1.1, including binary headers, multiplexing, and server push. Learn more
Uses passive listeners to improve scrolling performance
Mark your touch and wheel event listeners as `passive` to improve your page's scroll performance. Learn more
Avoid using document.write()
For users on slow connections, external scripts dynamically injected via document.write() can delay page load by tens of seconds. Learn more
Manifest's short_name won't be truncated when displayed on homescreen
Make your app's short_name fewer than 12 characters to ensure that it's not truncated on homescreens. Learn more
Configured for a custom splash screen
A default splash screen will be constructed for your app, but satisfying these requirements guarantee a high-quality splash screen that transitions the user from tapping the home screen icon to your app's first paint. Learn more
User can be prompted to Install the Web App
Browsers can proactively prompt users to add your app to their homescreen, which can lead to higher engagement. Learn more

Avoids an excessive DOM size319 nodes
Number of elements in the document. Browser engineers recommend pages contain fewer than ~1,500 DOM nodes. The sweet spot is a tree depth < 32 elements and fewer than 60 children/parent element. A large DOM can increase memory usage, cause longer style calculations, and produce costly layout reflows. Learn more

Compressed Images
The image compression check just looks at photo images and makes sure the quality isn't set too high. Images can usually be compressed pretty substantially without any noticeable reduction in visual quality. Learn more
Uses Progressive JPEGsScore: 100 %
A progressive JPEG is image created using the JPEG suite of compression algorithms that will 'fade in' in successive waves of lines until the entire image has completely arrived. They show the entire image right away, looking slightly pixelated until the image data is fully loaded. Learn more
Properly Sized ImagesPotential savings of 1,063 KB (~5,640 ms)
Serve images that are appropriately-sized to save cellular data and improve load time. Learn more
Offscreen imagesPotential savings of 1,177 KB (~6,250 ms)

First impression
Eliminates render-blocking JavaScript and CSS in above-the-fold content
This rule triggers when detecting that your HTML references a blocking external resource / file in the above-the-fold portion of your page. Learn more about JS - Learn more about CSS
Your page has 2 blocking CSS resources. This causes a delay in rendering your page.

Prioritizes visible content
This rule triggers when detecting that additional network round trips are required to render the above-the-fold content of the page. Learn more
Improves server response time
This rule triggers when detecting that your server response time is above 200 ms. Server response time measures how long it takes to load the necessary HTML to begin rendering the page from your server, subtracting out the network latency between Google and your server. Learn more
Avoids landing page redirects
Redirects trigger an additional HTTP request-response cycle and delay page rendering. In the best case, each redirect will add a single round trip (HTTP request-response), and in the worst it may result in multiple additional roundtrips to perform the DNS lookup, TCP handshake, and TLS negotiation in addition to the additional HTTP request-response cycle. As a result, you should minimize use of redirects to improve site performance. Learn more
Usability 100/100
Clicking logo always leads you to homepage.
Make it easy to get back to the homepage. Use your logo as a navigation button to return to the homepage.
Key CTAs are visible on the homepage.
Keep menus short, visible and sweet.
No ending trailing paths.
Always provide navigation options on footers and/or fixed header.
Suports multi-device experiences.Not applicable
Use wishlists/favouriting/saved baskets; social sharing; email; to facilitate seamless movement between devices or mobile platforms.
For category pages/search result with lots of products, make sure lazy-loading or pagination are used.
Load images asynchronously -- after the above-the-fold content is fully loaded, or conditionally, only when they appear in the browser’s viewport.
Possible to swipe to see more images or tap to enlarge them.
Allow for mobile gestures like swipe or tap to enlarge images, graphics and other contents, keeping good quality and focus.
Streamlines forms information entry.
Minimize the number of fields and autofill information wherever possible. Implement correct input types in fields, i.e. input type = email, number, etc. Make use of tabIndex to iterate through fields with the keyboard.
Forms error warnings.
Users are notified immediately when mistakes are made in a field, and guidance is provided on how to fix it.
Makes site search visible and user-friendly.Not applicable
Place your site search near the top of your pages, via an open text field or clear label. Offer filters to help users get what they need from search or group results per categories. Auto-complete is available in on-site search.
Keeps your user in a single browser window.
Switching between windows on a smartphone can be troublesome, and raises the risk that visitors might not find their way back to your site. Try to keep users in one place by avoiding calls-to-action that launch new windows.

Avoids Application Cache
Application Cache is deprecated. Learn more
Avoids WebSQL DB
Web SQL is deprecated. Consider using IndexedDB instead. Learn more
Avoids requesting the geolocation permission on page load
Users are mistrustful of or confused by sites that request their location without context. Consider tying the request to user gestures instead. Learn more
Avoids requesting the notification permission on page load
Users are mistrustful of or confused by sites that request to send notifications without context. Consider tying the request to user gestures instead. Learn more
Avoids deprecated APIs
Deprecated APIs will eventually be removed from the browser. Learn more
Allows to paste into password input fields
The main reason why password pasting improves security is because it helps to reduce password overload. Learn more
Registers a Service Worker
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
Responds 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
Uses HTTPS
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
Redirects HTTP traffic to HTTPS
If you've already set up HTTPS, make sure that you redirect all HTTP traffic to HTTPS. Learn more
Uses HTTP/2 for its own resources17 requests were not handled over HTTP/2
HTTP/2 offers many benefits over HTTP/1.1, including binary headers, multiplexing, and server push. Learn more
Uses passive listeners to improve scrolling performance
Mark your touch and wheel event listeners as `passive` to improve your page's scroll performance. Learn more
Avoid using document.write()
For users on slow connections, external scripts dynamically injected via document.write() can delay page load by tens of seconds. Learn more
Manifest's short_name won't be truncated when displayed on homescreen
Make your app's short_name fewer than 12 characters to ensure that it's not truncated on homescreens. Learn more
Configured for a custom splash screen
A default splash screen will be constructed for your app, but satisfying these requirements guarantee a high-quality splash screen that transitions the user from tapping the home screen icon to your app's first paint. Learn more
User can be prompted to Install the Web App
Browsers can proactively prompt users to add your app to their homescreen, which can lead to higher engagement. Learn more
