plusdental.de website review

10 files are served with short cache lifetimes, so returning visitors download them again (586 KiB).

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 1.9 s.

About 285 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.4 s faster on a phone.

Google Tag Manager costs a phone 1.0 s of main-thread work and 734 KiB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

7 third-party services load with your homepage (Google Tag Manager, TikTok and Cookiebot and others), adding 1,005 KiB and 1.2 s of main-thread time.

About 510 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 620 ms faster on a phone.

Your mobile performance score is 64 (desktop: 69). Pages that score under 90 lose visitors before the first paint.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 550 ms).

10 long tasks block the main thread while loading, the longest for 338 ms. During a long task the page ignores taps.

Polyfills for old browsers add 41 KiB JavaScript that modern phones do not need.

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

The page becomes fully interactive after 11.3 s. Good is under 3.8 s.

Scripts block taps and scrolling for 761 ms in total while the page loads. Good is under 200 ms.

Your largest element takes 4.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “PlusDental ist jetzt DR SMILE - Sie werden zum DR SMILE Kun…”. Most of its time is element render delay (1.9 s).

The first text or image appears after 2.3 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 3.5 s (Speed Index). Good is under 3.4 s.

1 image have no width and height attributes, so the layout jumps as each one loads.

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.

By the Sustainable Web Design model, a visit to your homepage emits about 0.43 g of CO₂e: 51.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

<html> element must have a lang attribute: 1 element on the page fails this check, rated serious by axe-core.

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

The <html> element has no lang attribute, so screen readers may read the page in the wrong voice and accent.

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

Your title is only 18 characters: “Dr. Smile handover”. Between 30 and 65 characters leaves room to say what you do and for whom.

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

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

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

No XML sitemap at https://plusdental.de/sitemap.xml, so Google discovers your pages only by following links.

The homepage links to only 2 pages on your own site, so visitors and crawlers find few routes into the rest of it.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

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://plusdental.de/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.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 ()”.

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 37 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 Analytics, Google Tag Manager and TikTok Pixel (measured from a US location before any click). A consent tool (Cookiebot) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 11 cookies (measured from a US location before any click).

Loading the homepage contacts 9 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
