thermo-slim.de website review

Your mobile performance score is 70. Pages that score under 90 lose visitors before the first paint.

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

replocdn.com costs a phone 0 ms of main-thread work and 299 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.

About 55 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

About 22 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.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 150 ms).

8 third-party services load with your homepage (Shopify, Google CDN and newsbreak.com and others), adding 660 KiB and 80 ms of main-thread time.

2 images could be 126 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

25 KiB could be saved by minifying CSS.

6 files are served with short cache lifetimes, so returning visitors download them again (9 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.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Your largest element takes 6.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “women holding imge”.

The page becomes fully interactive after 6.6 s. Good is under 3.8 s.

The first text or image appears after 2.7 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 4.4 s (Speed Index). Good is under 3.4 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 2.0 MB in 190 requests on a phone: other files 929 KiB (133), scripts 559 KiB (34) and images 275 KiB (9). Under 2 MB keeps phones on slow connections fast.

1 image is downloaded at several times the size a phone draws it, for example Money_Back_Guarantee_1_1.png at 820 px wide, shown at 175 px. Resized copies would save about 37 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 0.58 g of CO₂e: 69.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Links must have discernible text: 2 elements on the page fail this check, rated serious by axe-core.

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

2 images have no alt text, which hurts accessibility and image search.

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.

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

Elements with visible text labels do not have matching accessible names. (1 element).

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

Your title is only 22 characters: “ThermoSlim Deutschland”. Between 30 and 65 characters leaves room to say what you do and for whom.

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

2 links have no real href, so search engines can't follow them.

The homepage links to 20 pages on thermo-slim.de and 2 external pages.

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

Your homepage links to https://thermo-slim.de/pages/how-it-works and https://thermo-slim.de/apps/parcelpanel, which answer with an error. Visitors hit a dead end and search engines drop them.

https://thermo-slim.de/customer_authentication/redirect has no <title>, so Google invents the link text in results.

https://thermo-slim.de/customer_authentication/redirect is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

https://thermo-slim.de/pages/kontakt and https://thermo-slim.de/pages/contact all use the title “Kontakt”. Search engines can't tell which page to show for a search, so each competes with the others.

https://thermo-slim.de/products/thermoslim-body-sculpting-device, https://thermo-slim.de/pages/kontakt, https://thermo-slim.de/customer_authentication/redirect, https://thermo-slim.de/pages/contact, https://thermo-slim.de/collections/frontpage and https://thermo-slim.de/products/sculpt-conductive-gel and 4 others have no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 2 pages by a URL that isn't their canonical one, for example https://thermo-slim.de/pages/contact, whose canonical is https://thermo-slim.de/pages/kontakt. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://thermo-slim.de/customer_authentication/redirect and https://thermo-slim.de/collections/frontpage have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 14 pages linked from your homepage and read each the way a search engine does.

10 of 13 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

1 image is served at too low a resolution for sharp phone screens.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

Social proof on the homepage: “100k+ Happy Customers”. Pairing it with named testimonials or customer logos makes it far more convincing.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

The homepage carries about 343 words of visible text.

Before a visitor clicks anything, the page loads Hotjar and Klaviyo (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.

Opening the homepage sets 7 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.

Loading the homepage contacts 14 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
