Compare side by sideOne score from every part of this review. How it works
Speed
Use efficient cache lifetimes
1.8 s · 546 KiB71 files are served with short cache lifetimes, so returning visitors download them again (546 KiB).
Render-blocking requests
750 ms5 files block the first paint until they finish downloading. Deferring or inlining them could save about 750 ms.
Improve image delivery
450 ms · 118 KiB5 images could be 118 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 450 ms faster on a phone.
2,128 HTML elements
The page has 2,128 HTML elements. Above 1,500, rendering and every interaction get slower on phones.
Reduce unused CSS
150 ms · 14 KiBAbout 14 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.
2 third-party services on the page
2 third-party services load with your homepage (Google Tag Manager and Google Analytics), adding 178 KiB and 145 ms of main-thread time.
Reduce unused JavaScript
122 KiBAbout 122 KiB of JavaScript is downloaded but never used on this page.
4 long tasks on the main thread
4 long tasks block the main thread while loading, the longest for 101 ms. During a long task the page ignores taps.
Legacy JavaScript
13 KiBPolyfills for old browsers add 13 KiB JavaScript that modern phones do not need.
Chained critical requests
Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.
Forced reflow
Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.
