clarks.com.au website review

15 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.5 s.

The page has 3,606 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 52. Pages that score under 90 lose visitors before the first paint.

11 images could be 462 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

Klaviyo costs a phone 135 ms of main-thread work and 328 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.

8 third-party services load with your homepage (Klaviyo, Shopify and SearchSpring and others), adding 727 KiB and 197 ms of main-thread time.

11 files are served with short cache lifetimes, so returning visitors download them again (134 KiB).

About 118 KiB of JavaScript is downloaded but never used on this page.

2 long tasks block the main thread while loading, the longest for 58 ms. During a long task the page ignores taps.

Polyfills for old browsers add 25 KiB JavaScript that modern phones do not need.

About 11 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.

3 KiB could be saved by minifying JavaScript.

Your largest element takes 6.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The layout shifts by 0.454 while loading, so content jumps under the reader's thumb. Good is under 0.1.

The page becomes fully interactive after 10.4 s. Good is under 3.8 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 101 ms to 128 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

The first text or image appears after 2.6 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 3.5 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.2 s to 1.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

310726_Clarks_Campaign_Web_Banner_LightUp_Mobile.gif weighs 679 KiB. On a phone connection a single image that size takes seconds.

Your homepage downloads 3.0 MB in 333 requests on a phone: images 1.0 MB (41), other files 948 KiB (149) and scripts 750 KiB (92). Under 2 MB keeps phones on slow connections fast.

240926_Clarks_Web_Footwear_Frenzy_Sandals_Mobile_b747b59d-b4 is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

1 image (679 KiB) is JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

1 image is downloaded at several times the size a phone draws it, for example AP_logo_badge_6328x2204_blackmint_png.png at 6,328 px wide, shown at 60 px. Resized copies would save about 85 KiB.

2 images further down the page (130 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.84 g of CO₂e: 100.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Links must have discernible text: 35 elements on the page fail this check, rated serious by axe-core.

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

All page content should be contained by landmarks: 4 elements on the page fail this check, rated moderate by axe-core.

Headings should not be empty: 42 elements on the page fail this check, rated minor by axe-core.

Headings skip levels (h1 → h3), which makes the page harder to scan with a screen reader.

Your title is 69 characters, so Google will cut it off around 60: “Clarks Australia | Sandals, Sneakers & Boots | Footwear Frenzy Now On”.

Your <h1> is empty.

The homepage links to 364 pages on clarks.com.au and 8 external pages.

Your robots.txt lets ChatGPT search (OAI-SearchBot), ChatGPT (ChatGPT-User) and Perplexity (PerplexityBot) read the homepage but closes other sections to them, so answers about those pages can't cite you.

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

https://clarks.com.au/customer_authentication/redirect is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

https://clarks.com.au/customer_authentication/redirect, https://clarks.com.au/collections/footwear-frenzy-all-styles-99-under and https://clarks.com.au/collections/cloudsteppers-womens have no meta description, so Google writes the search snippet from whatever text it finds.

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

We fetched 15 pages linked from your homepage (of 153 found) and read each the way a search engine does.

30 of 52 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 error was logged to the browser console while the page loaded, for example “Key is missing from snippet”.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

Social proof on the homepage: 10 trust badges. Pairing it with named testimonials or customer logos makes it far more convincing.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 376 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 1 more (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 19 cookies (measured from a US location before any click).

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

Loading the homepage contacts 34 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
