Core Web Vitals

Max Potential First Input Delay


20 ms

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

Cumulative Layout Shift


0.058

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

Largest Contentful Paint


1.3 s

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

Opportunities

Serve images in next-gen formats


Potential savings of 1,116 KiB

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

Properly size images


Potential savings of 758 KiB

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

First Contentful Paint


0.9 s

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

Avoids an excessive DOM size


186 elements

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

Efficiently encode images


Potential savings of 546 KiB

Optimized images load faster and consume less cellular data.

JavaScript execution time


0.0 s

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

First Meaningful Paint


0.9 s

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

Time to Interactive


0.9 s

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

Initial server response time was short


Root document took 280 ms

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

Serve static assets with an efficient cache policy


16 resources found

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

Eliminate render-blocking resources


Potential savings of 650 ms

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

Speed Index


0.9 s

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

Minimizes main-thread work


0.2 s

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

Avoids enormous network payloads


Total size was 2,087 KiB

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

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.

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