kerakoll.com website review

About 525 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.3 s faster on a phone.

Your mobile performance score is 56 (desktop: 85). Pages that score under 90 lose visitors before the first paint.

5 third-party services load with your homepage (Google Tag Manager, iubenda and Unbounce and others), adding 705 KiB and 518 ms of main-thread time.

About 15 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

Google Tag Manager costs a phone 385 ms of main-thread work and 538 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.

A phone's processor spends 3.0 s on main-thread work while loading, 2.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 300 ms.

7 long tasks block the main thread while loading, the longest for 185 ms. During a long task the page ignores taps.

Polyfills for old browsers add 12 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

Desktop scores 85 but mobile only 56. A gap that wide usually means heavy scripts and images that hit phones hardest.

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 files are served with short cache lifetimes, so returning visitors download them again (4 KiB).

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Your largest element takes 8.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Choose your country and language to explore the Kerakoll we…”.

The page becomes fully interactive after 10.3 s. Good is under 3.8 s.

The first text or image appears after 3.4 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 6.3 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 83 ms to 134 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors wait 1.1 s for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 343 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 1.6 s to 1.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

By the Sustainable Web Design model, a visit to your homepage emits about 0.39 g of CO₂e: 47.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

32 elements use ARIA attributes their role does not allow, which confuses screen readers.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

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

Elements with visible text labels do not have matching accessible names. (32 elements).

Headings skip levels (h2 → h5), which makes the page harder to scan with a screen reader.

The robots meta tag says “noindex, follow”: Google is told not to list this page at all.

Your robots.txt disallows the whole site for every crawler, so search engines are told to stay out.

Google's crawler is blocked from indexing this page.

Your canonical URL points to int.kerakoll.com, not kerakoll.com, so Google may credit that host instead.

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

The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.

Your <h1> is empty.

Your robots.txt shuts out ChatGPT search (OAI-SearchBot), ChatGPT (ChatGPT-User), Claude search (Claude-SearchBot), Claude (Claude-User), Perplexity (PerplexityBot) and Perplexity (Perplexity-User). These fetch pages to answer people's questions and cite the source, so your site can't be quoted or linked in those answers.

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.kerakoll.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.

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.

The homepage has only about 91 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.

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.

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