reefsupplies.ca website review

About 873 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.1 s faster on a phone.

9 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.4 s.

A phone's processor spends 5.0 s on main-thread work while loading, 2.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 4,352 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 53. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Shopify, joy.so and squarecdn.com and others), adding 1.7 MB and 628 ms of main-thread time.

Shopify costs a phone 380 ms of main-thread work and 915 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.

7 long tasks block the main thread while loading, the longest for 377 ms. During a long task the page ignores taps.

About 54 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.

joy.so costs a phone 118 ms of main-thread work and 379 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.

9 files are served with short cache lifetimes, so returning visitors download them again (182 KiB).

1 image could be 39 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.

32 KiB could be saved by minifying JavaScript.

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

Polyfills for old browsers add 29 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.

Your largest element takes 12.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The page becomes fully interactive after 18.3 s. Good is under 3.8 s.

Visually, the page fills in at 6.1 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 489 ms in total while the page loads. Good is under 200 ms.

The first text or image appears after 2.4 s on a phone. Good is under 1.8 s.

2 images have no width and height attributes, so the layout jumps as each one loads.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 105 ms to 112 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.4 MB in 198 requests on a phone: scripts 1.9 MB (87), other files 673 KiB (77) and fonts 328 KiB (9). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.96 g of CO₂e: 115.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

62 elements hidden from screen readers can still receive keyboard focus.

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

9 tap targets are too small or too close together to hit reliably with a finger.

Some lists contain elements other than list items, which screen readers announce wrongly.

Some list items are not inside a list.

Elements must only use permitted ARIA attributes: 1 element on the page fails this check, rated serious by axe-core.

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

Document should not have more than one banner landmark: 1 element on the page fails this check, rated moderate by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 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.

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

5 form fields have no label, so screen readers announce an empty box and autofill guesses.

Elements with visible text labels do not have matching accessible names. (1 element).

Your title is 91 characters, so Google will cut it off around 60: “Canada's #1 Saltwater Aquarium Store: ReefSupplies.ca - 100k+ Orders — Reef Supplies Cana…”.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

There are 2 <h1> headlines (“Reef Supplies Canada” and “Reef Supplies Canada”). One clear main headline is easier for people and search engines.

Your meta description is 318 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.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 256 pages on reefsupplies.ca and 3 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

https://www.reefsupplies.ca/pages/live-support-reef-supplies, https://www.reefsupplies.ca/apps/iwish, https://www.reefsupplies.ca/pages/joy-loyalty-page, https://www.reefsupplies.ca/pages/personalized-reef-equipment-recommendation and https://www.reefsupplies.ca/collections/bundles have no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 3 pages by a URL that isn't their canonical one, for example https://www.reefsupplies.ca/collections/sale/products/bulk-di-resin-in-mylar-bag-color-changing-fills-one-10-cartridge, whose canonical is https://www.reefsupplies.ca/products/bulk-di-resin-in-mylar-bag-color-changing-fills-one-10-cartridge. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://www.reefsupplies.ca/pages/joy-loyalty-page has no <h1> headline, so visitors and search engines get no clear main topic.

https://www.reefsupplies.ca/apps/iwish and https://www.reefsupplies.ca/pages/joy-loyalty-page have under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 15 pages linked from your homepage (of 98 found) and read each the way a search engine does.

2 errors were logged to the browser console while the page loaded, for example “Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'register')”.

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.

The homepage carries about 1,343 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Meta Pixel and TikTok Pixel (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 15 cookies, 1 of them by other companies (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 32 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
