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


0.139

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

Largest Contentful Paint


0.7 s

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

Opportunities

Eliminate render-blocking resources


Potential savings of 490 ms

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

Avoids enormous network payloads


Total size was 916 KiB

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

First Contentful Paint


0.7 s

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

First Meaningful Paint


0.7 s

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

Uses efficient cache policy on static assets


3 resources found

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

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.

Time to Interactive


0.7 s

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

Speed Index


0.9 s

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

Avoids an excessive DOM size


139 elements

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

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.

Properly size images


Potential savings of 455 KiB

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

Serve images in next-gen formats


Potential savings of 239 KiB

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

Initial server response time was short


Root document took 150 ms

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