intersport.de website review

Your mobile performance score is 62. Pages that score under 90 lose visitors before the first paint.

About 361 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 600 ms faster on a phone.

33 files are served with short cache lifetimes, so returning visitors download them again (854 KiB).

15 images could be 535 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

14 files block the first paint until they finish downloading. Deferring or inlining them could save about 450 ms.

A phone's processor spends 2.1 s on main-thread work while loading, 966 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

4 third-party services load with your homepage (Usercentrics CMP, Google Tag Manager and Amplience and others), adding 1.2 MB and 66 ms of main-thread time.

The page has 1,639 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Amplience costs a phone 0 ms of main-thread work and 940 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.

8 long tasks block the main thread while loading, the longest for 244 ms. During a long task the page ignores taps.

About 14 KiB of CSS is downloaded but never applied on this page.

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

Your largest element takes 6.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Outdoorjacken für nasses Herbstwetter”.

The page becomes fully interactive after 11.5 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 4.7 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 321 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 111 ms to 118 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 0.8 s to 0.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.2 MB in 112 requests on a phone: images 1.1 MB (48), scripts 969 KiB (39) and HTML 73 KiB (1). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.62 g of CO₂e: 74.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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.

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

Elements with visible text labels do not have matching accessible names. (48 elements).

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

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

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

The homepage links to 154 pages on intersport.de 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.intersport.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.

We fetched 15 pages linked from your homepage (of 116 found) and read each the way a search engine does.

Large scripts ship without source maps.

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.

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

The homepage carries about 872 words of visible text.

Before a visitor clicks anything, the page loads Google Tag Manager (measured from a US location before any click). A consent tool (Usercentrics) is installed; check it blocks these until visitors agree where the law requires it.

Loading the homepage contacts 10 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
