First Contentful Paint2546.712 ms

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

First meaningful paint3747.347 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: 61%

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

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. 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 80/100 Industry: Blog / News

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.

Listing/distributive pages with many items implements deferred loading techniques

Fails if the website not provides at least one of the following: lazy-loading, load more buttons, paginator. Not provides a clear reference about the total amount of items in a portfolio or blog page.

Listing/distributive pages are not the only way to browse through all the articles

Fails if doesn't provide at least one of the following: next/prev case buttons, related cases listing, or any other way to keep browsing without going back and forth to the overview page.

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.

Search and filtering are available and prominent (search results or category listing pages)

Fails if no search functionallity. Filtering is appropriate but not provided or if sorting is prioritized over filtering in the visual hierarchy.

Articles can be shared

Fails if doesn't provide sharing options. Doesn't provide any of the following article meta information: title, description and image.

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.

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

First meaningful paint3699.166 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: 72%

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

Leverage browser caching for the following cacheable resources:

Avoids an excessive DOM size658 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: 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. Source: WebPagetest - 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 80/100 Industry: Blog / News

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.

Listing/distributive pages with many items implements deferred loading techniques

Fails if the website not provides at least one of the following: lazy-loading, load more buttons, paginator. Not provides a clear reference about the total amount of items in a portfolio or blog page.

Listing/distributive pages are not the only way to browse through all the articles

Fails if doesn't provide at least one of the following: next/prev case buttons, related cases listing, or any other way to keep browsing without going back and forth to the overview page.

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.

Search and filtering are available and prominent (search results or category listing pages)

Fails if no search functionallity. Filtering is appropriate but not provided or if sorting is prioritized over filtering in the visual hierarchy.

Articles can be shared

Fails if doesn't provide sharing options. Doesn't provide any of the following article meta information: title, description and image.

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.

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.
