cannonsuk.com website review

The page has 11,492 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 8.8 s on main-thread work while loading, 2.8 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Adroll, Feefo.com and Shopify and others), adding 1.9 MB and 1.2 s of main-thread time.

Your mobile performance score is 67. Pages that score under 90 lose visitors before the first paint.

7 files block the first paint until they finish downloading. Deferring or inlining them could save about 700 ms.

About 527 KiB of JavaScript is downloaded but never used on this page.

Adroll costs a phone 469 ms of main-thread work and 145 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.

23 files are served with short cache lifetimes, so returning visitors download them again (251 KiB).

Shopify costs a phone 136 ms of main-thread work and 526 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.

Feefo.com costs a phone 142 ms of main-thread work and 421 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 CDN costs a phone 114 ms of main-thread work and 298 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.

11 long tasks block the main thread while loading, the longest for 200 ms. During a long task the page ignores taps.

75 KiB JavaScript is shipped twice across bundles. Google estimates it would make the page about 50 ms faster on a phone.

2 images could be 27 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 50 ms faster on a phone.

Polyfills for old browsers add 70 KiB JavaScript that modern phones do not need.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

About 48 KiB of CSS is downloaded but never applied on this page.

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.

4 KiB could be saved by minifying JavaScript.

By the Sustainable Web Design model, a visit to your homepage emits about 1.24 g of CO₂e: 149.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

4 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

ARIA dialog and alertdialog nodes should have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

1 frame has no title, so screen-reader users cannot tell what it contains.

2 images have no alt text, which hurts accessibility and image search.

Heading levels should only increase by one: 1 element on the page fails this check, rated moderate by axe-core.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

7 visible links have no text or label, so screen readers cannot say where they go.

Structured data found (Organization, Store and WebSite) but with 1 problem, for example “WebSite: url is not an absolute URL ("www.cannonsuk.com")”.

7 links have no real href, so search engines can't follow them.

Your <h1> is empty.

The homepage links to 677 pages on cannonsuk.com and 3 external pages.

https://www.cannonsuk.com/customer_authentication/redirect has no <title>, so Google invents the link text in results.

https://www.cannonsuk.com/customer_authentication/redirect and https://www.cannonsuk.com/collections/air-track-club have no meta description, so Google writes the search snippet from whatever text it finds.

https://www.cannonsuk.com/customer_authentication/redirect has no <h1> headline, so visitors and search engines get no clear main topic.
