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.

Largest Contentful Paint


0.7 s

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

Opportunities

Speed Index


0.7 s

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

Avoids enormous network payloads


Total size was 467 KiB

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

JavaScript execution time


0.2 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 81 KiB

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

Avoid an excessive DOM size


1,777 elements

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

Eliminate render-blocking resources


Potential savings of 80 ms

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

Uses efficient cache policy on static assets


1 resource found

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

First Meaningful Paint


0.5 s

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

Time to Interactive


0.5 s

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

Minimizes main-thread work


0.6 s

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

First Contentful Paint


0.4 s

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

Reduce unused CSS


Potential savings of 52 KiB

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

Initial server response time was short


Root document took 220 ms

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

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.
