Load time8022 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. Source: WebPagetest - Learn more
Page load is fast enough on 3G
A fast page load over a 3G network ensures a good mobile user experience. Source: Lighthouse - Learn more
First byte1391 ms
The time from the initial request to the first byte of the response. Source: WebPagetest - Learn more
First Contentful Paint1410 ms
First contentful paint marks the time at which the first text/image is painted. Source: Lighthouse - Learn more
First meaningful paint1410 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. Source: Lighthouse - Learn more
Estimated Input Latency12 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 (< 50ms), users may perceive your app as laggy. Source: Lighthouse - 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.

Interactive marks the time at which the page is fully interactive. Source: Lighthouse - Learn more
Page weight
Uses compression (gzip, zopfli, deflate, brotli)Score: 40%
This rule triggers when detecting that compressible resources were served without gzip compression. Source: WebPagetest - Learn more
Uses a CDN for all static assetsScore: 0%
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. The 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. Source: WebPagetest - 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. Source: PageSpeed Insights - 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.

Source: PageSpeed Insights - Learn more
Avoids an excessive DOM size635 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. Source: Lighthouse - 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. Source: Lighthouse - Learn more
Uses Progressive JPEGsn/a
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. Source: WebPagetest - Learn more
Properly Sized Images
Serve images that are appropriately-sized to save cellular data and improve load time. Source: Lighthouse - Learn more
Offscreen images
Consider lazy-loading offscreen images to improve page load speed and time to interactive. Source: Lighthouse - 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. Source: PageSpeed Insights - 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. Source: PageSpeed Insights - Learn more
Usability 83/100 Industry: Corporate / Institutional
Brand logo linked to homepage
Fails if doesn't have a logo or clicking it doesn't lead you to homepage.
No ending trailing paths
Fails if doesn't provide at least one of the following: main navigation options on footers, fixed or 'smart' headers/burger-icon, Back to top or close buttons.
Active section is highlighted in navigation menus
Fails if current section or page is not visually highlighted in navigation menus, except for internal section pages where it's accepted not to highlight the parent section.
Listing/overview pages with many items implements deferred loading techniquesNot applicable
Fails if the website doesn't provide at least one of the following: lazy-loading, load more buttons, paginator. Doesn't provide a clear reference about the total amount of items in a portfolio or blog page.
Prevent layout shiftings when loading media. Set width and height attributes on both <img> and <video> tags
Fails if transitioning from placeholders to final images changes the rendered size of the element as media loads. Not using a solid color placeholder occupying the same dimensions as the target image, or techniques such as LQIP or SQIP that hint at the content of a media item before it loads. These changes can be disorienting for users and trigger expensive DOM layout operations that consume system resources and contribute to jank.
Make it easy to contact you
Fails if the website does not provide all of the following: easy to find contact options, tap to call, mailto on emails, addresses do not link to gMaps, except being embedded.
Carousels are generally avoided (but they are acceptable if they are well implemented)
Fails if any of the following are seen: carousels auto-rotate, text is not legible, swipe is not supported, next images do not load within 1 second of swipe.
The website supports autofill for all form fields and the fields are tagged for the appropriate information from autofillNot applicable
Fails if fields are not tagged for efficient browser-based autofill, making users enter data that is already known either by the website or the OS. Not filling a standard field or filling fields with the wrong content, i.e. puts house number and street name into the same field when there are separate fields for each.
The most appropriate keyboard for the input type is provided firstNot applicable
Fails if most helpful keyboard not provided, i.e. input types text, tel, email, password, capitalization when appropiate, etc.
All mistakes made in forms are clearly highlighted in real time, and instructions for correct completion are provided in real timeNot applicable
Fails if mistakes and guidance for correct completion are not highlighted in real time and/or error messages are ambiguous or unfriendly.

Avoids deprecated APIs
Deprecated APIs will eventually be removed from the browser. Source: Lighthouse - 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. Source: Lighthouse - 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. Source: Lighthouse - 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. Source: Lighthouse - 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.

Uses HTTP/2 for its own resources15 requests not served via HTTP/2
HTTP/2 offers many benefits over HTTP/1.1, including binary headers, multiplexing, and server push. Source: Lighthouse - 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. Source: Lighthouse - 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. Source: Lighthouse - 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. Source: Lighthouse - 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. Source: Lighthouse - 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. Source: Lighthouse - Learn more

A content delivery network (CDN) is a system for distributing resources to servers geographically closer to users. The 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. Source: WebPagetest - 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. Source: PageSpeed Insights - 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. Source: PageSpeed Insights - Learn more
