Core Web Vitals
Max Potential First Input Delay
60 ms
The maximum potential First Input Delay that your users could experience is the duration of the longest task.
Cumulative Layout Shift
0.422
Cumulative Layout Shift measures the movement of visible elements within the viewport.
Largest Contentful Paint
1.5 s
Largest Contentful Paint marks the time at which the largest text or image is painted.
Opportunities
Speed Index
0.8 s
Speed Index shows how quickly the contents of a page are visibly populated.
First Meaningful Paint
0.6 s
First Meaningful Paint measures when the primary content of a page is visible.
Total Blocking Time
10 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
Time to Interactive
0.9 s
Time to interactive is the amount of time it takes for the page to become fully interactive.
Avoids enormous network payloads
Total size was 479 KiB
Large network payloads cost users real money and are highly correlated with long load times.
Properly size images
Potential savings of 12 KiB
Serve images that are appropriately-sized to save cellular data and improve load time.
Initial server response time was short
Root document took 320 ms
Keep the server response time for the main document short because all other requests depend on it.
Avoids an excessive DOM size
509 elements
A large DOM will increase memory usage, cause longer style calculations, and produce costly layout reflows
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.
Serve static assets with an efficient cache policy
13 resources found
A long cache lifetime can speed up repeat visits to your page.
First Contentful Paint
0.6 s
First Contentful Paint marks the time at which the first text or image is painted.
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.
Avoid multiple page redirects
Potential savings of 230 ms
Redirects introduce additional delays before the page can be loaded.
Reduce unused JavaScript
Potential savings of 119 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.
These measurements are for each new visitor, for returning visitors the footprint would be lower based on caching mechanisms.
