coravin.se website review

A phone's processor spends 4.5 s on main-thread work while loading, 2.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 950 ms.

8 third-party services load with your homepage (Google Tag Manager, Klaviyo and Clarity and others), adding 2.8 MB and 648 ms of main-thread time.

Google Tag Manager costs a phone 289 ms of main-thread work and 381 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.

8 images could be 256 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Shopify costs a phone 61 ms of main-thread work and 1.6 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.

The page has 1,719 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

gotolstoy.com costs a phone 58 ms of main-thread work and 509 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 243 KiB of JavaScript is downloaded but never used on this page.

26 files are served with short cache lifetimes, so returning visitors download them again (222 KiB).

6 long tasks block the main thread while loading, the longest for 211 ms. During a long task the page ignores taps.

About 70 KiB of CSS is downloaded but never applied on this page.

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 CSS.

The page becomes fully interactive after 19.3 s. Good is under 3.8 s.

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

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 9.8 MB in 308 requests on a phone: media 5.7 MB (3), images 1.5 MB (53) and scripts 1.3 MB (104). Under 2 MB keeps phones on slow connections fast.

1 image further down the page (113 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 2.78 g of CO₂e: 334.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

Headings skip levels (h3 → h6 and h2 → h4), which makes the page harder to scan with a screen reader.

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

Structured data found (Organization, WebPage and WebSite) but with 1 problem, for example “Organization: url points at a different host (https://www.coravin.nl)”.

The homepage links to 95 pages on coravin.se and 32 external pages.

https://www.coravin.se/collections/all, https://www.coravin.se/collections/accessories and https://www.coravin.se/pages/trade-create-account use the same meta description. A description written for each page earns more clicks.

We fetched 15 pages linked from your homepage (of 39 found) and read each the way a search engine does.

The page uses 2 deprecated browser APIs that will stop working in future browsers (“Fenced Frame API is deprecated and scheduled for removal.”).

1 third-party cookie is set on load; browsers are restricting these, so whatever relies on them breaks.

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

Chrome logged issues while loading the page (“Cookie”).

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.
