One score from every part of this review. How it works
Speed
Render-blocking requests
1.1 s4 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.
Mobile performance score: 87
87/100Your mobile performance score is 87. Pages that score under 90 lose visitors before the first paint.
Reduce unused CSS
450 ms · 74 KiBAbout 74 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.
2,605 HTML elements
The page has 2,605 HTML elements. Above 1,500, rendering and every interaction get slower on phones.
Improve image delivery
72 KiB9 images could be 72 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.
Reduce unused JavaScript
69 KiBAbout 69 KiB of JavaScript is downloaded but never used on this page.
1 long task on the main thread
1 long task block the main thread while loading, the longest for 55 ms. During a long task the page ignores taps.
3 third-party services on the page
3 third-party services load with your homepage (Shopify, Bugsnag and shop.app), adding 101 KiB and 39 ms of main-thread time.
Use efficient cache lifetimes
30 KiB3 files are served with short cache lifetimes, so returning visitors download them again (30 KiB).
Chained critical requests
Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.
Forced reflow
Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Main-thread work: 1.9 s
A phone's processor spends 1.9 s on main-thread work while loading, 375 ms of it running JavaScript. That is comfortably low.
Server response: 18 ms
18 msYour server sent the HTML in 18 ms, well inside Google's 600 ms guideline.
Core Web Vitals
Largest Contentful Paint: 3.9 s
3.9 sYour largest element takes 3.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.
Time to Interactive: 5.0 s
5.0 sThe page becomes fully interactive after 5.0 s. Good is under 3.8 s.
Not enough real-visitor data yet
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.
4 checks passed
Speed Index: 3.4 s
3.4 sVisually, the page fills in at 3.4 s (Speed Index), inside the 3.4 s “good” threshold.
First Contentful Paint: 1.4 s
1.4 sThe first text or image appears after 1.4 s, inside the 1.8 s “good” threshold.
Cumulative Layout Shift: 0
0The layout barely moves while loading (CLS 0, good is under 0.1).
Total Blocking Time: 3 ms
3 msScripts block the page for only 3 ms while loading. Good is under 200 ms.
Images and page weight
An image on the first screen is lazy-loaded
KATSUDO-SPARTA_GYM_099_1.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).
About 0.5 g of CO₂ per visit
0.48 gBy the Sustainable Web Design model, a visit to your homepage emits about 0.48 g of CO₂e: 57.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
3 checks passed
Page weight: 1.7 MB in 141 requests
1.7 MBYour homepage downloads 1.7 MB in 141 requests on a phone: other files 748 KiB (82), scripts 339 KiB (31) and images 305 KiB (14). That is a lean page.
Images use modern formats
Every sizeable image is WebP, AVIF or SVG.
Images are sized for phones
No image is downloaded at more than three times the size it is drawn on a phone.
Accessibility
17 text elements with low contrast
17 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.
Scrollable region must have keyboard access (3 elements)
Scrollable region must have keyboard access: 3 elements on the page fail this check, rated serious by axe-core.
Landmarks should have a unique role or role/label/title (i.e. accessible name) combination (1 element)
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.
All page content should be contained by landmarks (1 element)
All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.
32 links without text
32 visible links have no text or label, so screen readers cannot say where they go.
Headings skip levels
Headings skip levels (h1 → h6), which makes the page harder to scan with a screen reader.
2 checks passed
Every image has alt text
All 86 images in the HTML carry an alt attribute.
49 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 53 WCAG 2.2 A/AA and best-practice rules on the phone render: 49 passed and 4 failed. 3 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.
SEO
Title is short (26 characters)
Your title is only 26 characters: “Katsudo – Kampfsportbedarf”. Between 30 and 65 characters leaves room to say what you do and for whom.
No structured data
No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.
Meta description is long (214 characters)
Your meta description is 214 characters; Google truncates after about 160, so the end of your pitch is cut.
842 internal links, 5 external
The homepage links to 842 pages on katsudo.de and 5 external pages.
5 checks passed
One H1 headline
Your main headline reads: “Katsudo”.
Canonical URL set
The canonical URL is https://www.katsudo.de/.
Open Graph tags complete
Open Graph tags are complete, so shared links show a title, description and image.
robots.txt in place
robots.txt is in place and points crawlers to your sitemap.
XML sitemap found
Your XML sitemap is reachable at https://www.katsudo.de/sitemap.xml.
AI search readiness
No Organization structured data
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.
3 checks passed
AI answer engines may read the site
Your robots.txt lets the crawlers behind ChatGPT search, Claude and Perplexity read the site and cite it in answers.
Text is in the HTML
Your server sends the page's text in the HTML (685 words), so crawlers that don't run JavaScript still read it.
llms.txt published
The site publishes https://www.katsudo.de/llms.txt (6 KiB, 8 links), a plain-text guide to the site for AI tools.
Other pages
1 page without a meta description
https://www.katsudo.de/collections/sale-1 has no meta description, so Google writes the search snippet from whatever text it finds.
13 pages without an H1
https://www.katsudo.de/collections/tatami, https://www.katsudo.de/collections/sale-1, https://www.katsudo.de/collections/schutzausruestung, https://www.katsudo.de/collections/kopfschutz-und-helme, https://www.katsudo.de/collections/box-kopfschutz and https://www.katsudo.de/collections/kickbox-und-thaibox-kopfschutz and 7 others have no <h1> headline, so visitors and search engines get no clear main topic.
13 pages with very little text
https://www.katsudo.de/collections/tatami, https://www.katsudo.de/collections/sale-1, https://www.katsudo.de/collections/schutzausruestung, https://www.katsudo.de/collections/kopfschutz-und-helme, https://www.katsudo.de/collections/box-kopfschutz and https://www.katsudo.de/collections/kickbox-und-thaibox-kopfschutz and 7 others have under 150 words in the HTML.

No analytics detected
