zym.com website review

5 images could be 286 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 950 ms faster on a phone.

8 third-party services load with your homepage (Google CDN, Bold Commerce and Privy and others), adding 2.8 MB and 918 ms of main-thread time.

About 982 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 150 ms faster on a phone.

Your mobile performance score is 66. Pages that score under 90 lose visitors before the first paint.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 850 ms.

Google CDN costs a phone 428 ms of main-thread work and 1.1 MB 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.

34 files are served with short cache lifetimes, so returning visitors download them again (481 KiB).

A phone's processor spends 2.9 s on main-thread work while loading, 1.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Bold Commerce costs a phone 197 ms of main-thread work and 485 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.

Shopify costs a phone 75 ms of main-thread work and 637 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.

About 87 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

9 long tasks block the main thread while loading, the longest for 236 ms. During a long task the page ignores taps.

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

Polyfills for old browsers add 43 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.

The page becomes fully interactive after 23.7 s. Good is under 3.8 s.

Your largest element takes 6.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Product image”.

Visually, the page fills in at 5.7 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 315 ms in total while the page loads. Good is under 200 ms.

5 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' largest content (lcp) went from 1.6 s to 1.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

Your homepage downloads 4.5 MB in 204 requests on a phone: scripts 2.3 MB (80), other files 1.0 MB (83) and images 708 KiB (16). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.29 g of CO₂e: 154.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

1 link inside paragraphs relies on colour alone to stand out.

All page content should be contained by landmarks: 8 elements on the page fail 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.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

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.

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

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

Headings skip levels (h3 → h6), which makes the page harder to scan with a screen reader.

No meta description, so Google writes its own snippet from whatever text it finds.

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

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

Open Graph is missing og:description, so shared links fall back to guesses.

The homepage links to 23 pages on zym.com and 5 external pages.

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

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

https://www.zym.com/collections/sport, https://www.zym.com/collections/accessories, https://www.zym.com/customer_authentication/redirect and https://www.zym.com/pages/contact-us have no meta description, so Google writes the search snippet from whatever text it finds.

https://www.zym.com/collections/sport, https://www.zym.com/collections/accessories, https://www.zym.com/customer_authentication/redirect and https://www.zym.com/pages/contact-us have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 10 pages linked from your homepage and read each the way a search engine does.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

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

Your longest form asks for 10 fields (5 required). Every extra field lowers completion.

The homepage has only about 151 words of visible text; thin pages give Google and first-time buyers little to go on.

The homepage shows no opening hours. If customers visit or call, show when.

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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

Before a visitor clicks anything, the page loads Google Analytics, Google Tag Manager and Meta 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 12 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 31 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
