Core Web Vitals

Max Potential First Input Delay


30 ms

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

Cumulative Layout Shift


0

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

Largest Contentful Paint


0.4 s

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

Opportunities

Properly size images


Potential savings of 39 KiB

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

Speed Index


0.4 s

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

Minimizes main-thread work


0.3 s

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

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.

Initial server response time was short


Root document took 90 ms

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

Avoids an excessive DOM size


280 elements

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

Time to Interactive


0.3 s

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

Serve images in next-gen formats


Potential savings of 63 KiB

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

Avoid serving legacy JavaScript to modern browsers


Potential savings of 16 KiB

Polyfills and transforms enable legacy browsers to use new JavaScript features. However, many aren't necessary for modern browsers. For your bundled JavaScript, adopt a modern script deployment strategy using module/nomodule feature detection to reduce the amount of code shipped to modern browsers, while retaining support for legacy browsers.

Avoids enormous network payloads


Total size was 286 KiB

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

First Contentful Paint


0.3 s

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

First Meaningful Paint


0.3 s

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