purityvision.cz website review

A phone's processor spends 6.5 s on main-thread work while loading, 2.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 4,811 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 66. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Shopify, Cookiebot and lhinsights.com and others), adding 1.3 MB and 711 ms of main-thread time.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 800 ms.

Shopify costs a phone 413 ms of main-thread work and 886 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 378 KiB of JavaScript is downloaded but never used on this page.

13 long tasks block the main thread while loading, the longest for 206 ms. During a long task the page ignores taps.

172 KiB could be saved by minifying JavaScript.

9 files are served with short cache lifetimes, so returning visitors download them again (107 KiB).

3 images could be 46 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

About 40 KiB of CSS is downloaded but never applied on this page.

Polyfills for old browsers add 12 KiB JavaScript that modern phones do not need.

6 KiB could be saved by minifying CSS.

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.

The page becomes fully interactive after 13.0 s. Good is under 3.8 s.

Visually, the page fills in at 8.0 s (Speed Index). Good is under 3.4 s.

Your largest element takes 5.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Purity Vision CZ”.

Scripts block taps and scrolling for 337 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 123 ms to 141 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.5 s to 1.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.3 MB in 278 requests on a phone: scripts 1.2 MB (87), other files 999 KiB (111) and images 726 KiB (45). Under 2 MB keeps phones on slow connections fast.

Shopify_slide_banner_eshop_mobil-19.png is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

By the Sustainable Web Design model, a visit to your homepage emits about 0.94 g of CO₂e: 112.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Elements must only use permitted ARIA attributes: 2 elements on the page fail this check, rated serious by axe-core.

All page content should be contained by landmarks: 9 elements on the page fail this check, rated moderate by axe-core.

12 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: 4 elements on the page fail this check, rated minor by axe-core.

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

Elements with visible text labels do not have matching accessible names. (2 elements).

Your meta description is 176 characters; Google truncates after about 160, so the end of your pitch is cut.

Your <h1> is empty.

The homepage links to 289 pages on purityvision.cz and 19 external pages.

We fetched 15 pages linked from your homepage (of 130 found) and read each the way a search engine does.

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

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

Social proof on the homepage: 61 testimonial or review blocks. 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.

The homepage shows no opening hours. If customers visit or call, show when.

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 3,248 words of visible text.

The page uses urgency cues (a countdown or limited-time wording).

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

Opening the homepage sets 15 cookies (measured from a US location before any click).

Loading the homepage contacts 30 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
