ucarpart.com website review

About 1.3 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.3 s faster on a phone.

16 files are served with short cache lifetimes, so returning visitors download them again (356 KiB).

Your mobile performance score is 43. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 5.3 s on main-thread work while loading, 2.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 4,684 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Shopify, Google Tag Manager and Google CDN and others), adding 2.5 MB and 1.3 s of main-thread time.

About 114 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

Shopify costs a phone 411 ms of main-thread work and 673 KiB 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.

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 450 ms.

Google CDN costs a phone 223 ms of main-thread work and 685 KiB 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.

Google Tag Manager costs a phone 253 ms of main-thread work and 334 KiB 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.

amaicdn.com costs a phone 200 ms of main-thread work and 403 KiB 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.

Polyfills for old browsers add 72 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 250 ms faster on a phone.

14 long tasks block the main thread while loading, the longest for 197 ms. During a long task the page ignores taps.

12 images could be 103 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

1 form field has no label, so screen readers announce an empty box and autofill guesses.
