saintz.cz website review

The page has 3,137 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 87. Pages that score under 90 lose visitors before the first paint.

Shopify costs a phone 0 ms of main-thread work and 395 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 87 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 150 ms faster on a phone.

3 third-party services load with your homepage (Google Tag Manager, Shopify and Google/Doubleclick Ads), adding 556 KiB and 137 ms of main-thread time.

Polyfills for old browsers add 14 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

3 long tasks block the main thread while loading, the longest for 118 ms. During a long task the page ignores taps.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 100 ms.

2 images could be 22 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.

Your largest element takes 3.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image. Most of its time is element render delay (1.8 s).

The page becomes fully interactive after 5.8 s. Good is under 3.8 s.

Visually, the page fills in at 4.3 s (Speed Index). Good is under 3.4 s.

By the Sustainable Web Design model, a visit to your homepage emits about 0.30 g of CO₂e: 36.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Structured data found (OnlineStore, Organization and WebSite) but with 1 problem, for example “Organization: missing name”.

The homepage links to 412 pages on saintz.cz and 8 external pages.

robots.txt blocks GPTBot, ClaudeBot, Applebot-Extended and CCBot, which collect pages to train models. That's a legitimate choice and doesn't by itself stop the site appearing in AI answers, which the crawlers above handle.

We fetched 15 pages linked from your homepage (of 198 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.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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.

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 1,077 words of visible text.

Before a visitor clicks anything, the page loads Google Tag Manager (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 1 cookie (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 2 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
