kotschi-consulting.com website review

1 image could be 15.2 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 72.2 s faster on a phone.

5 third-party services load with your homepage (Wix, Cloudflare and Sentry and others), adding 16.5 MB and 105 ms of main-thread time.

Wix costs a phone 90 ms of main-thread work and 16.5 MB 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.

Your mobile performance score is 55. Pages that score under 90 lose visitors before the first paint.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 800 ms.

1 long task block the main thread while loading, the longest for 529 ms. During a long task the page ignores taps.

About 165 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 330 ms faster on a phone.

Polyfills for old browsers add 10 KiB JavaScript that modern phones do not need.

2 files are served with short cache lifetimes, so returning visitors download them again (5 KiB).

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

2 KiB JavaScript is shipped twice across bundles.

Your largest element takes 75.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “HEMS_Approach.png”.

The page becomes fully interactive after 75.5 s. Good is under 3.8 s.

Visually, the page fills in at 6.6 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 479 ms in total while the page loads. Good is under 200 ms.

The first text or image appears after 2.2 s on a phone. Good is under 1.8 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.

Your homepage downloads 16.6 MB in 101 requests on a phone: images 14.3 MB (38), other files 1.7 MB (21) and scripts 459 KiB (38). Under 2 MB keeps phones on slow connections fast.

44d3a5_11cca5cbdc434197a2c41321341f4f99~mv2.gif weighs 14.1 MB. On a phone connection a single image that size takes seconds.

1 image (14.1 MB) 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.

44d3a5_11cca5cbdc434197a2c41321341f4f99~mv2.gif 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 4.72 g of CO₂e: 566.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 tap target is too small or too close together to hit reliably with a finger.

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

Headings skip levels (h2 → h6), which makes the page harder to scan with a screen reader.

Your meta description is only 52 characters: “Digital Business, Home Energy Management, Smart Home”. 70 to 160 characters is enough to sell the click.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

No XML sitemap at https://www.kotschi-consulting.com/sitemap.xml, so Google discovers your pages only by following links.

The homepage links to 25 pages on kotschi-consulting.com and 2 external pages.

Your Organization JSON-LD is missing logo, sameAs (social profiles) and description. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

There is no https://www.kotschi-consulting.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.

robots.txt blocks GPTBot, ClaudeBot, Google-Extended, 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.

Your homepage links to https://www.kotschi-consulting.com/erfolgsstories, https://www.kotschi-consulting.com/news, https://www.kotschi-consulting.com/bernd-kotschi, https://www.kotschi-consulting.com/kontakt, https://www.kotschi-consulting.com/leistungen/home-energy-management-systems and https://www.kotschi-consulting.com/leistungen/smart-home-platforms and 4 others, which answer with an error. Visitors hit a dead end and search engines drop them.

https://www.kotschi-consulting.com/leistungen and https://www.kotschi-consulting.com/leistungen/digital-business-innovation have no meta description, so Google writes the search snippet from whatever text it finds.

https://www.kotschi-consulting.com/leistungen has under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 12 pages linked from your homepage and read each the way a search engine does.

4 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 400 ()”.

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.

The homepage has only about 149 words of visible text; thin pages give Google and first-time buyers little to go on.

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

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

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.

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