zone3.es website review

8 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.2 s.

A phone's processor spends 5.5 s on main-thread work while loading, 1.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 4,511 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

About 747 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

Your mobile performance score is 58. Pages that score under 90 lose visitors before the first paint.

4 images could be 211 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 600 ms faster on a phone.

7 third-party services load with your homepage (Klaviyo, Shopify and Yotpo and others), adding 1.8 MB and 524 ms of main-thread time.

About 101 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

14 files are served with short cache lifetimes, so returning visitors download them again (130 KiB).

Shopify costs a phone 191 ms of main-thread work and 917 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.

Klaviyo costs a phone 203 ms of main-thread work and 618 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 246 ms. During a long task the page ignores taps.

29 KiB could be saved by minifying JavaScript.

18 KiB could be saved by minifying CSS.

152 KiB JavaScript is shipped twice across bundles.

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.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Your largest element takes 8.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Person swimming underwater wearing a Zone3 wetsuit and cap.”.

The page becomes fully interactive after 17.4 s. Good is under 3.8 s.

Visually, the page fills in at 7.8 s (Speed Index). Good is under 3.4 s.

Real visitors wait 258 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 139 ms to 269 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

The first text or image appears after 2.8 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 281 ms in total while the page loads. Good is under 200 ms.

Your homepage downloads 4.1 MB in 396 requests on a phone: scripts 1.9 MB (220), images 873 KiB (24) and other files 854 KiB (123). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.17 g of CO₂e: 140.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has no accessible name, so screen readers announce just “button”.

Elements must only use permitted ARIA attributes: 8 elements on the page fail this check, rated serious by axe-core.

1 image has no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 8 elements on the page fail this check, rated moderate by axe-core.

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

Headings skip levels (h2 → h5), which makes the page harder to scan with a screen reader.

Your title is 66 characters, so Google will cut it off around 60: “ZONE3 ES | Neoprenos, Tritrajes y Gafas De Natación – ZONE3 ESPAÑA”.

Your meta description is 215 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 235 pages on zone3.es and 0 external pages.

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

https://zone3.es/pages/zone3-wetsuit-guide, https://zone3.es/pages/zone3-triwear-guide, https://zone3.es/pages/zone3-swimwear-guide and https://zone3.es/pages/zone3-goggle-guide have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 81 found) and read each the way a search engine does.

Social proof on the homepage: 2 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 725 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Tag Manager, Klaviyo 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 16 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 27 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
