Mobile Friendliness 67/100

Content is not blocked for zoom/scale

The `[user-scalable="no"]` parameter is not present in the `<meta name="viewport">` element and the `[maximum-scale]` parameter is not less than 2.Source: Lighthouse - 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. Source: Lighthouse - Learn more

Uses legible font sizes

Font sizes less than 12px are too small to be legible and require mobile visitors to “pinch to zoom” in order to read. Strive to have >60% of page text ≥12px. Source: Lighthouse - Learn more

Color Contrast is satisfactory

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

First contentful paint marks the time at which the first text/image is painted. Source: Lighthouse - Learn more

First meaningful paint3270.633 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.

Uses compression (gzip, zopfli, deflate, brotli)Score: 100%

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

Uses a CDN for all static assetsScore: 99%

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

Avoids an excessive DOM size448 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

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 86/100 Industry: Promotional

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 techniques

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.

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.

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.

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.

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.

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.

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. Source: Lighthouse - Learn more

Redirects HTTP traffic to HTTPS

If you've already set up HTTPS, make sure that you redirect all HTTP traffic to HTTPS. Source: Lighthouse - Learn more

Uses HTTP/2 for its own resources

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
