damesens.cz website review

Your mobile performance score is 84. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Shopify, Google Tag Manager and Klaviyo and others), adding 831 KiB and 529 ms of main-thread time.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 500 ms.

A phone's processor spends 3.9 s on main-thread work while loading, 870 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

About 276 KiB of JavaScript is downloaded but never used on this page.

Shopify costs a phone 201 ms of main-thread work and 299 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.

The page has 2,189 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

7 images could be 159 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

1 long task block the main thread while loading, the longest for 134 ms. During a long task the page ignores taps.

Polyfills for old browsers add 70 KiB JavaScript that modern phones do not need.

16 files are served with short cache lifetimes, so returning visitors download them again (65 KiB).

51 KiB could be saved by minifying JavaScript.

About 10 KiB of CSS is downloaded but never applied on this page.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

5 KiB JavaScript is shipped twice across bundles.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

The page becomes fully interactive after 11.8 s. Good is under 3.8 s.

The layout shifts by 0.178 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Your largest element takes 3.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Maximal nutrition, minimal harm”.

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

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 103 ms to 114 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.6 s to 1.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 13.6 MB in 250 requests on a phone: media 11.2 MB (1), scripts 902 KiB (105) and other files 680 KiB (81). Under 2 MB keeps phones on slow connections fast.

Certain ARIA roles must be contained by particular parents: 3 elements on the page fail this check, rated critical by axe-core.

1 element use ARIA attributes their role does not allow, which confuses screen readers.

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

Links must have discernible text: 1 element on the page fails this check, rated serious 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.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.
