scubadiving.com.au website review

The page has 3,679 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 62. Pages that score under 90 lose visitors before the first paint.

About 141 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 750 ms faster on a phone.

8 third-party services load with your homepage (Shopify, Intercom and Klaviyo and others), adding 1.2 MB and 667 ms of main-thread time.

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 550 ms.

12 images could be 503 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

About 62 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

A phone's processor spends 3.6 s on main-thread work while loading, 1.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Shopify costs a phone 257 ms of main-thread work and 611 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.

6 long tasks block the main thread while loading, the longest for 180 ms. During a long task the page ignores taps.

15 files are served with short cache lifetimes, so returning visitors download them again (40 KiB).

Polyfills for old browsers add 19 KiB JavaScript that modern phones do not need.

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

The page becomes fully interactive after 14.2 s. Good is under 3.8 s.

Visually, the page fills in at 6.8 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 117 ms to 137 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

The first text or image appears after 2.7 s on a phone. Good is under 1.8 s.

Your homepage downloads 4.1 MB in 481 requests on a phone: images 1.3 MB (19), scripts 1.3 MB (262) and other files 999 KiB (171). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.16 g of CO₂e: 139.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

ARIA attributes must conform to valid values: 2 elements on the page fail this check, rated critical by axe-core.

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

1 element hidden from screen readers can still receive keyboard focus.

All page content should be contained by landmarks: 14 elements on the page fail this check, rated moderate by axe-core.

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

1 visible link has no text or label, so screen readers cannot say where it goes.

There is no <h1>, so neither visitors nor Google get a clear main headline.

Your title is 80 characters, so Google will cut it off around 60: “ADRENO Ocean Outfitters | World's Largest Dive Store – Adreno - Ocean Outfitters”.

Your meta description is 221 characters; Google truncates after about 160, so the end of your pitch is cut.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

The homepage links to 851 pages on scubadiving.com.au and 6 external pages.

Your Organization JSON-LD is missing logo, sameAs (social profiles) and description. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

https://adreno.com.au/collections/black-friday-2026, https://adreno.com.au/collections/spearguns, https://adreno.com.au/collections/open-muzzle-spearguns, https://adreno.com.au/collections/closed-muzzle-spearguns, https://adreno.com.au/collections/roller-spearguns and https://adreno.com.au/collections/timber-spearguns and 9 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 199 found) and read each the way a search engine does.

6 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_TUNNEL_CONNECTION_FAILED”.

Social proof on the homepage: 1 trust badge. 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.
