Core Web Vitals

Max Potential First Input Delay


100 ms

The maximum potential First Input Delay that your users could experience is the duration of the longest task.

Cumulative Layout Shift


0.008

Cumulative Layout Shift measures the movement of visible elements within the viewport.

Largest Contentful Paint


2.2 s

Largest Contentful Paint marks the time at which the largest text or image is painted.

Opportunities

First Contentful Paint


1.2 s

First Contentful Paint marks the time at which the first text or image is painted.

Reduce unused JavaScript


Potential savings of 154 KiB

Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.

Total Blocking Time


110 ms

Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.

JavaScript execution time


1.1 s

Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.

Time to Interactive


4.2 s

Time to interactive is the amount of time it takes for the page to become fully interactive.

Eliminate render-blocking resources


Potential savings of 610 ms

Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.

Defer offscreen images


Potential savings of 763 KiB

Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive.

Minimize main-thread work


2.5 s

Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.

Avoid enormous network payloads


Total size was 4,799 KiB

Large network payloads cost users real money and are highly correlated with long load times.

Avoid an excessive DOM size


1,371 elements

A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows

Initial server response time was short


Root document took 70 ms

Keep the server response time for the main document short because all other requests depend on it.

Reduce unused CSS


Potential savings of 181 KiB

Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity.

First Meaningful Paint


1.2 s

First Meaningful Paint measures when the primary content of a page is visible.

Speed Index


2.0 s

Speed Index shows how quickly the contents of a page are visibly populated.

Serve images in next-gen formats


Potential savings of 898 KiB

Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption.

Uses efficient cache policy on static assets


1 resource found

A long cache lifetime can speed up repeat visits to your page.

Properly size images


Potential savings of 396 KiB

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

Switch to green hosting


One of the easiest things to do that instantly reduces your impact.

Notes

* These are assets not hosted on the same domain e.g. tracking scripts, iframe embeds, or files hosted on a CDN.

** This was only counted from 11.Apr.2021.

These measurements are for each new visitor, for returning visitors the footprint would be lower based on caching mechanisms.
