9,859 HTML elements
The page has 9,859 HTML elements. Above 1,500, rendering and every interaction get slower on phones.
Main-thread work: 5.1 s
A phone's processor spends 5.1 s on main-thread work while loading, 1.8 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.
Improve image delivery
450 ms · 928 KiB12 images could be 928 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.
8 third-party services on the page
8 third-party services load with your homepage (omnisnippet1.com, Shopify and rebuyengine.com and others), adding 3.8 MB and 904 ms of main-thread time.
Mobile performance score: 64
64/100Your mobile performance score is 64. Pages that score under 90 lose visitors before the first paint.

Shopify adds 242 ms
242 msShopify costs a phone 242 ms of main-thread work and 2.7 MB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

Use efficient cache lifetimes
212 KiB15 files are served with short cache lifetimes, so returning visitors download them again (212 KiB).
Reduce unused CSS
150 ms · 52 KiBAbout 52 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.
13 long tasks on the main thread
13 long tasks block the main thread while loading, the longest for 147 ms. During a long task the page ignores taps.
Legacy JavaScript
29 KiBPolyfills for old browsers add 29 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.
