intersport.ch website review

13 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.2 s.

The page has 7,364 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 5.2 s on main-thread work while loading, 2.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Usercentrics CMP, Google Tag Manager and crazyrocket.io and others), adding 1.7 MB and 1.8 s of main-thread time.

Your mobile performance score is 63. Pages that score under 90 lose visitors before the first paint.

Usercentrics CMP costs a phone 792 ms of main-thread work and 192 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.

Google Tag Manager costs a phone 681 ms of main-thread work and 862 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 526 KiB of JavaScript is downloaded but never used on this page.

18 images could be 518 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

15 long tasks block the main thread while loading, the longest for 310 ms. During a long task the page ignores taps.

Klaviyo costs a phone 124 ms of main-thread work and 320 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.

26 files are served with short cache lifetimes, so returning visitors download them again (168 KiB).

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 ms).

Polyfills for old browsers add 19 KiB JavaScript that modern phones do not need.

About 15 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.

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

5 KiB could be saved by minifying JavaScript.

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.

The page becomes fully interactive after 20.5 s. Good is under 3.8 s.

Visually, the page fills in at 8.8 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 777 ms in total while the page loads. Good is under 200 ms.

Real visitors wait 215 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Your largest element takes 3.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

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

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 139 ms to 162 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 2.4 s to 2.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.7 MB in 435 requests on a phone: scripts 1.8 MB (105), images 1.6 MB (138) and other files 1.1 MB (159). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.34 g of CO₂e: 160.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 tap targets are too small or too close together to hit reliably with a finger.

Heading levels should only increase by one: 1 element on the page fails this check, rated moderate by axe-core.

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.

Your title is 71 characters, so Google will cut it off around 60: “INTERSPORT Onlineshop | Sportartikel online kaufen – INTERSPORT Schweiz”.

Your <h1> is empty.

The homepage links to 705 pages on intersport.ch and 4 external pages.

Your Organization JSON-LD is missing logo, 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.

https://www.intersport.ch/collections/all is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

https://www.intersport.ch/policies/shipping-policy has no meta description, so Google writes the search snippet from whatever text it finds.

https://www.intersport.ch/collections/all, https://www.intersport.ch/collections/winterjacken, https://www.intersport.ch/collections/outdoorhosen, https://www.intersport.ch/collections/skihosen, https://www.intersport.ch/collections/skijacken and https://www.intersport.ch/collections/unterhemd and 7 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 78 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://lantern.roeye.com/track.php?fingerprint=273cbf67-8349-499b-865c-f6424e47af62&referrer=&landingpage=https%3A%2F%2Fwww.intersport.ch%2F&useragent=Mozilla%2F5.0%20(iPhone%3B%20CPU%20iPhone%20OS%2.

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.

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.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

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

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.

The homepage carries about 1,712 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager and Klaviyo (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.

Opening the homepage sets 17 cookies (measured from a US location before any click).

Loading the homepage contacts 34 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
