Load time63476 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 byte1591 ms
The time from the initial request to the first byte of the response. Source: WebPagetest - Learn more
First Contentful Paint2441.245 ms
First contentful paint marks the time at which the first text/image is painted. Source: Lighthouse - Learn more
First meaningful paint2819.565 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: 93%
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 size653 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 JPEGsScore: 0 %
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

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. Source: PageSpeed Insights - 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 90/100 Industry: Retail Omnichannel
Autocomplete is used to suggest popular searches (but can be ignored)
Fails if no autocomplete or if the user is not allowed to ignore the autocomplete.
Filtering is available and prominent on search results or category listing pages
Fails if filtering is appropriate but not provided or if sorting is prioritized over filtering in the visual hierarchy.
The product details follow a set pattern making it easier to compare, e.g. bullet points with tech specs
Fails if different product description information formatting from one page to another.
It is possible to check in-store product availability
Fails if in-store product availability is not provided.
All product images are zoomable, without blur
Fails if product images are blurry at full zoom.
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.
There is a choice to convert without creating an account, i.e. Guest checkout
Fails if no guest checkout.
The most appropriate keyboard for the input type is provided first
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 autofill
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 time
Fails if mistakes and guidance for correct completion are not highlighted in real time and/or error messages are ambiguous or unfriendly.

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 resources2 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

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. Source: PageSpeed Insights - 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 90/100 Industry: Retail Omnichannel
Autocomplete is used to suggest popular searches (but can be ignored)
Fails if no autocomplete or if the user is not allowed to ignore the autocomplete.
Filtering is available and prominent on search results or category listing pages
Fails if filtering is appropriate but not provided or if sorting is prioritized over filtering in the visual hierarchy.
The product details follow a set pattern making it easier to compare, e.g. bullet points with tech specs
Fails if different product description information formatting from one page to another.
It is possible to check in-store product availability
Fails if in-store product availability is not provided.
All product images are zoomable, without blur
Fails if product images are blurry at full zoom.
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.
There is a choice to convert without creating an account, i.e. Guest checkout
Fails if no guest checkout.
The most appropriate keyboard for the input type is provided first
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 autofill
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 time
Fails if mistakes and guidance for correct completion are not highlighted in real time and/or error messages are ambiguous or unfriendly.

First meaningful paint3039.373 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.

Page weight
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: 94%
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
