kunbus.com website review

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.9 s.

8 files are served with short cache lifetimes, so returning visitors download them again (250 KiB).

Your mobile performance score is 72 (desktop: 99). Pages that score under 90 lose visitors before the first paint.

About 56 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 410 ms faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 300 ms).

About 64 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.

50 KiB could be saved by minifying JavaScript.

3 images could be 121 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

1 third-party service load with your homepage (Usercentrics CMP), adding 222 KiB and 71 ms of main-thread time.

1 long task block the main thread while loading, the longest for 55 ms. During a long task the page ignores taps.

Desktop scores 99 but mobile only 72. A gap that wide usually means heavy scripts and images that hit phones hardest.

7 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.

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.

The first text or image appears after 3.2 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 5.3 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 5.1 s. Good is under 3.8 s.

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

sps-logo-800xx500-ea5506e1.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).

1 image is downloaded at several times the size a phone draws it, for example hero-2025-91e7b831.webp at 1,920 px wide, shown at 390 px. Resized copies would save about 33 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 0.19 g of CO₂e: 22.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

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.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

No meta description, so Google writes its own snippet from whatever text it finds.

Your title is only 11 characters: “KUNBUS GmbH”. Between 30 and 65 characters leaves room to say what you do and for whom.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

Structured data found (BreadcrumbList, ImageObject, Page and WebPage) but with 5 problems, for example “ImageObject: contentUrl is not an absolute URL ("https://www.kunbus.com/assets/images/5/hero-2025-951cc5ee.jpg")”.

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

Your <h1> is empty.

The homepage links to 13 pages on kunbus.com and 8 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.

There is no https://www.kunbus.com/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

Your homepage links to https://www.kunbus.com/en/en, https://www.kunbus.com/en/en/about-kunbus, https://www.kunbus.com/en/en/career, https://www.kunbus.com/en/en/job-openings, https://www.kunbus.com/en/en/agb and https://www.kunbus.com/en/en/coc and 2 others, which answer with an error. Visitors hit a dead end and search engines drop them.

We fetched 8 pages linked from your homepage and read each the way a search engine does.

11 of 21 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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.

The homepage has only about 180 words of visible text; thin pages give Google and first-time buyers little to go on.

There is no form on the homepage, so every lead has to click through to another page first.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

Loading the homepage contacts 5 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
