Core Web Vitals
Max Potential First Input Delay
140 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task.
Cumulative Layout Shift
1.779
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
10.0 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
First Meaningful Paint
1.2 s
First Meaningful Paint measures when the primary content of a page is visible.
Reduce unused CSS
Potential savings of 218 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity.
JavaScript execution time
0.4 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this.
Reduce initial server response time
Root document took 770 ms
Keep the server response time for the main document short because all other requests depend on it.
Defer offscreen images
Potential savings of 6,039 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive.
Avoid enormous network payloads
Total size was 15,052 KiB
Large network payloads cost users real money and are highly correlated with long load times.
First Contentful Paint
1.2 s
First Contentful Paint marks the time at which the first text or image is painted.
Minimizes main-thread work
1.5 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this.
Speed Index
4.6 s
Speed Index shows how quickly the contents of a page are visibly populated.
Eliminate render-blocking resources
Potential savings of 600 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles.
Serve images in next-gen formats
Potential savings of 12,741 KiB
Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption.
Time to Interactive
8.2 s
Time to interactive is the amount of time it takes for the page to become fully interactive.
Minify JavaScript
Potential savings of 98 KiB
Minifying JavaScript files can reduce payload sizes and script parse time.
Total Blocking Time
110 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
Avoids an excessive DOM size
698 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
Serve static assets with an efficient cache policy
6 resources found
A long cache lifetime can speed up repeat visits to your page.
Properly size images
Potential savings of 6,051 KiB
Serve images that are appropriately-sized to save cellular data and improve load time.
Minify CSS
Potential savings of 161 KiB
Minifying CSS files can reduce network payload sizes.
Reduce unused JavaScript
Potential savings of 408 KiB
Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.
Notes
* These are assets not hosted on the same domain e.g. tracking scripts, iframe embeds, or files hosted on a CDN.
** This was only counted from 11.Apr.2021.
These measurements are for each new visitor, for returning visitors the footprint would be lower based on caching mechanisms.
