zinus.es website review

Your mobile performance score is 71. Pages that score under 90 lose visitors before the first paint.

About 121 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 600 ms faster on a phone.

About 69 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.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 350 ms.

4 third-party services load with your homepage (Usercentrics CMP, Shopify and instana.io and others), adding 373 KiB and 204 ms of main-thread time.

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

1 long task block the main thread while loading, the longest for 52 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 11 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 6.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Green_Tea_Luxe_Memory_Foam_Mattress_lifestyle.jpg”.

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

The page becomes fully interactive after 6.4 s. Good is under 3.8 s.

The first text or image appears after 2.0 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.2 s to 1.2 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 2.8 MB in 245 requests on a phone: images 1.4 MB (99), other files 691 KiB (89) and scripts 472 KiB (45). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.79 g of CO₂e: 95.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

2 images have no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 2 elements on the page fail this check, rated moderate by axe-core.

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

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

There are 2 <h1> headlines (“<img src="//www.zinus.es/cdn/shop/files/Zinus.Log…” and “¿Nuestra receta especial para un descanso regener…”). One clear main headline is easier for people and search engines.

Your meta description is 179 characters; Google truncates after about 160, so the end of your pitch is cut.

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

The homepage links to 102 pages on zinus.es and 20 external pages.

Your homepage links to https://www.zinus.es/about, https://www.zinus.es/support and https://www.zinus.es/products/pressure-relief-green-tea-mattress, which answer with an error. Visitors hit a dead end and search engines drop them.

https://www.zinus.es/blogs/zinus and https://www.zinus.es/blog all use the title “Guía de colchones, consejos e inspiración | Blog de Zinus España”. Search engines can't tell which page to show for a search, so each competes with the others.

https://www.zinus.es/pages/habitaciones-dormitorio and https://www.zinus.es/pages/acerca-de-nosotros use the same meta description. A description written for each page earns more clicks.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://www.zinus.es/blog, whose canonical is https://www.zinus.es/blogs/zinus. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

We fetched 15 pages linked from your homepage (of 38 found) and read each the way a search engine does.

5 errors were logged to the browser console while the page loaded, for example “klaviyo.init is not a function”.

2 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

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 266 words of visible text.

Before a visitor clicks anything, the page loads Google Analytics and Google Tag Manager (measured from a US location before any click). A consent tool (Usercentrics) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 7 cookies (measured from a US location before any click).

Loading the homepage contacts 9 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
