asmc.de website review

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.3 s.

The page has 5,079 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 4.7 s on main-thread work while loading, 1.4 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

About 821 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 450 ms faster on a phone.

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

8 third-party services load with your homepage (Google Tag Manager, Shopify and Clarity and others), adding 1.4 MB and 860 ms of main-thread time.

18 images could be 584 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 350 ms faster on a phone.

Google Tag Manager costs a phone 362 ms of main-thread work and 536 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 60 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

16 files are served with short cache lifetimes, so returning visitors download them again (194 KiB).

10 long tasks block the main thread while loading, the longest for 183 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

35 KiB could be saved by minifying JavaScript.

Polyfills for old browsers add 11 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.

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

The page becomes fully interactive after 14.6 s. Good is under 3.8 s.

Your largest element takes 4.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

Visually, the page fills in at 5.4 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 338 ms in total while the page loads. Good is under 200 ms.

Your homepage downloads 5.0 MB in 276 requests on a phone: images 1.6 MB (76), other files 1.6 MB (114) and scripts 1.4 MB (65). Under 2 MB keeps phones on slow connections fast.

2026-09-28_RHE_Trek_n-Eat_Hero-Banner_Mobil_800x800px_DE.jpg is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

1 image is downloaded at several times the size a phone draws it, for example Visa_1913cf1c-7738-48c6-8eff-d1238c0c27ad.svg at 240 px wide, shown at 66 px. Resized copies would save about 28 KiB.

5 images (289 KiB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

1 image further down the page (87 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.43 g of CO₂e: 171.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

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

35 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. (23 elements).

The homepage links to 563 pages on asmc.de and 20 external pages.

/blogs/magazin, /pages/unsere-filialen, /pages/asmc-prime-league, /pages/contact and /pages/merkliste have no meta description, so Google writes the search snippet from whatever text it finds.

/pages/asmc-prime-league, /collections/bestseller, /products/asmc-namensschild-kunststoff, /products/bundeswehr-original-rangabzeichen-schwarz, /products/bundeswehr-original-taetigkeitsabzeichen-fallschirmspringer and /products/mil-tec-rucksack-us-assault-pack-large-36-liter and 5 others have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 197 found) and read each the way a search engine does.

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

HSTS is set, but max-age is 91 days; one year is the recommended minimum.

1 link go through two or more redirects, for example https://www.asmc.de/account.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

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.

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 1,262 words of visible text.

DMARC is set to p=none, so mail pretending to be asmc.de is still delivered. Reports are on, so moving to quarantine is the next step.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager and Microsoft Clarity (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 3 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 33 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
