Mobile Friendliness 100/100

Configures the viewport

This rule triggers when detecting that your page does not specify a viewport, or specifies a viewport that does not adapt to different devices. Learn more

Content is sized correctly for the viewport

If the width of your app's content doesn't match the width of the viewport, your app might not be optimized for mobile screens. Learn more

Size tap targets appropriately

This rule triggers when detecting that certain tap targets (e.g. buttons, links, or form fields) may be too small or too close together for a user to easily tap on a touchscreen. Learn more

Uses legible font sizes

This rule triggers when detecting that text in the page is too small to be legible. Learn more

Color Contrast is satisfactory

Low-contrast text is difficult or impossible for many users to read. Background and foreground colors should have a sufficient enough contrast ratio to guarantee readability. Learn more

Speed

Load time8423 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 byte2512 ms

The time from the initial request to the first byte of the response. Learn more

First meaningful paint4336 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)4673 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)4673 ms

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: 100%

This rule triggers when detecting that compressible resources were served without gzip compression. Learn more

Uses a CDN for all static assetsScore: 15%

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 caching

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

Leverage browser caching for the following cacheable resources:

Avoids an excessive DOM size316 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

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 Images

Serve images that are appropriately-sized to save cellular data and improve load time. Learn more

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.Not applicable

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.Not applicable

Allow for mobile gestures like swipe or tap to enlarge images, graphics and other contents, keeping good quality and focus.

Streamlines forms information entry.Not applicable

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.Not applicable

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.

Best Practices 60/100

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
