sgkb.ch website review

11 files are served with short cache lifetimes, so returning visitors download them again (726 KiB).

About 307 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.2 s faster on a phone.

The page has 3,782 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 70 (desktop: 92). Pages that score under 90 lose visitors before the first paint.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 700 ms.

About 62 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

4 long tasks block the main thread while loading, the longest for 224 ms. During a long task the page ignores taps.

19 KiB JavaScript is shipped twice across bundles. Google estimates it would make the page about 150 ms faster on a phone.

3 images could be 107 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

The HTML itself could arrive sooner: redirects, a slow server response or missing compression delay everything after it.

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.

Your largest element takes 5.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Visually, the page fills in at 5.0 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 5.4 s. Good is under 3.8 s.

Scripts block taps and scrolling for 256 ms in total while the page loads. Good is under 200 ms.

The first text or image appears after 2.0 s on a phone. Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 83 ms to 85 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 0.8 s to 0.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

SGKB-Visa-Jackpot-Hochformat.webp 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 0.41 g of CO₂e: 49.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

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

ARIA input fields must have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

1 link inside paragraphs relies on colour alone to stand out.

<svg> elements with an img or image role must have alternative text: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 37 elements on the page fail this check, rated moderate by axe-core.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

4 form fields have no label, so screen readers announce an empty box and autofill guesses.

1 visible link has no text or label, so screen readers cannot say where it goes.

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. (3 elements).

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

The homepage links to 205 pages on sgkb.ch and 9 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

We fetched 15 pages linked from your homepage (of 138 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.

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

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 478 words of visible text.

Opening the homepage sets 3 cookies (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.
