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.
