Core Web Vitals
Max Potential First Input Delay
120 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task.
Cumulative Layout Shift
0.001
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
3.3 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 1,272 KiB
Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption.
Eliminate render-blocking resources
Potential savings of 620 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.
Avoid an excessive DOM size
1,052 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Avoid enormous network payloads
Total size was 3,498 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Reduce unused CSS
Potential savings of 43 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 170 ms
Keep the server response time for the main document short because all other requests depend on it.
Minify JavaScript
Potential savings of 43 KiB
Minifying JavaScript files can reduce payload sizes and script parse time.
Time to Interactive
3.4 s
Time to interactive is the amount of time it takes for the page to become fully interactive.
Efficiently encode images
Potential savings of 1,000 KiB
Optimized images load faster and consume less cellular data.
First Contentful Paint
1.0 s
First Contentful Paint marks the time at which the first text or image is painted.
Minimizes main-thread work
1.8 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
Total Blocking Time
80 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
JavaScript execution time
0.5 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
Serve static assets with an efficient cache policy
45 resources found
A long cache lifetime can speed up repeat visits to your page.
Reduce unused JavaScript
Potential savings of 500 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
Speed Index
1.5 s
Speed Index shows how quickly the contents of a page are visibly populated.
First Meaningful Paint
1.0 s
First Meaningful Paint measures when the primary content of a page is visible.

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.
