posedla.cz website review

A phone's processor spends 4.9 s on main-thread work while loading, 2.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Shopify and Clarity and others), adding 2.1 MB and 1.0 s of main-thread time.

Your mobile performance score is 62. Pages that score under 90 lose visitors before the first paint.

About 763 KiB of JavaScript is downloaded but never used on this page.

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 650 ms.

Google Tag Manager costs a phone 529 ms of main-thread work and 839 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 183 ms of main-thread work and 724 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 1,939 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Klaviyo costs a phone 108 ms of main-thread work and 330 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.

13 long tasks block the main thread while loading, the longest for 180 ms. During a long task the page ignores taps.

About 29 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 files are served with short cache lifetimes, so returning visitors download them again (120 KiB).

Polyfills for old browsers add 19 KiB JavaScript that modern phones do not need.

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

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 21.0 s. Good is under 3.8 s.

Your largest element takes 5.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 139 ms to 170 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Scripts block taps and scrolling for 491 ms in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 5.1 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.9 s to 1.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 28.6 MB in 333 requests on a phone: media 24.7 MB (3), scripts 2.0 MB (146) and other files 863 KiB (113). Under 2 MB keeps phones on slow connections fast.

1 image (54 KiB) is JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

By the Sustainable Web Design model, a visit to your homepage emits about 8.09 g of CO₂e: 971.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Certain ARIA roles must contain particular children: 1 element on the page fails this check, rated critical by axe-core.

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

Scrollable region must have keyboard access: 2 elements on the page fail this check, rated serious by axe-core.

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

All page content should be contained by landmarks: 3 elements on the page fail this check, rated moderate by axe-core.

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

Alternative text of images should not be repeated as text: 1 element on the page fails this check, rated minor by axe-core.

1 link has no real href, so search engines can't follow it.

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

The homepage links to 89 pages on posedla.cz and 67 external pages.

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

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

https://posedla.com/collections/gift-cards, https://posedla.com/collections/services, https://posedla.com/pages/b2b and https://posedla.com/customer_authentication/redirect have no meta description, so Google writes the search snippet from whatever text it finds.

https://posedla.com/pages/gift-guide, https://posedla.com/collections/custom-3d-printed-saddle, https://posedla.com/products/joyseat, https://posedla.com/products/joyseat-tt, https://posedla.com/products/joyseat-indoor and https://posedla.com/collections/accessories and 9 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 33 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “jdgm.$ is not a function”.

Large scripts ship without source maps.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

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

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.

The homepage carries about 599 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Tag Manager, Klaviyo and Microsoft Clarity (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 8 cookies, 1 of them by other companies (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 34 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
