Speed
Use efficient cache lifetimes
2.1 s · 511 KiB11 files are served with short cache lifetimes, so returning visitors download them again (511 KiB).
Improve image delivery
1.6 s · 402 KiB3 images could be 402 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.6 s faster on a phone.
Mobile performance score: 68
68/100Your mobile performance score is 68 (desktop: 89). Pages that score under 90 lose visitors before the first paint.
Reduce unused JavaScript
640 ms · 105 KiBAbout 105 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 640 ms faster on a phone.
Reduce unused CSS
480 ms · 126 KiBAbout 126 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 480 ms faster on a phone.
Adobe Scene7 adds 0 ms
0 msAdobe Scene7 costs a phone 0 ms of main-thread work and 505 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.
3 third-party services on the page
3 third-party services load with your homepage (Optanon, adobeaemcloud.com and Adobe Scene7), adding 941 KiB and 119 ms of main-thread time.
1 long task on the main thread
1 long task block the main thread while loading, the longest for 56 ms. During a long task the page ignores taps.
Legacy JavaScript
9 KiBPolyfills for old browsers add 9 KiB JavaScript that modern phones do not need.
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.
2 checks passed
Main-thread work: 0.5 s
A phone's processor spends 0.5 s on main-thread work while loading, 190 ms of it running JavaScript. That is comfortably low.
Server response: 3 ms
3 msYour server sent the HTML in 3 ms, well inside Google's 600 ms guideline.
Core Web Vitals
Largest Contentful Paint: 8.8 s
8.8 sYour largest element takes 8.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Description”.
Time to Interactive: 8.8 s
8.8 sThe page becomes fully interactive after 8.8 s. Good is under 3.8 s.
Speed Index: 5.3 s
5.3 sVisually, the page fills in at 5.3 s (Speed Index). Good is under 3.4 s.
First Contentful Paint: 2.4 s
2.4 sThe first text or image appears after 2.4 s on a phone. Good is under 1.8 s.
2 images without width and height
2 images have no width and height attributes, so the layout jumps as each one loads.
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.
2 checks passed
Cumulative Layout Shift: 0.001
0.001The layout barely moves while loading (CLS 0.001, good is under 0.1).
Total Blocking Time: 6 ms
6 msScripts block the page for only 6 ms while loading. Good is under 200 ms.
Images and page weight
An image on the first screen is lazy-loaded
PWRCOM-215 EBTD Rollout_Divers-4 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).
2 images in older formats
2 images (577 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.
About 0.4 g of CO₂ per visit
0.39 gBy the Sustainable Web Design model, a visit to your homepage emits about 0.39 g of CO₂e: 47.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
2 checks passed
Page weight: 1.4 MB in 31 requests
1.4 MBYour homepage downloads 1.4 MB in 31 requests on a phone: images 946 KiB (8), scripts 209 KiB (9) and stylesheets 125 KiB (2). That is a lean page.
Images are sized for phones
No image is downloaded at more than three times the size it is drawn on a phone.
Accessibility
1 form field without a label
1 form field has no label, so screen readers announce an empty box and autofill guesses.
2 checks passed
Every image has alt text
All 13 images in the HTML carry an alt attribute.
42 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 42 WCAG 2.2 A/AA and best-practice rules on the phone render: 42 passed and 0 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.
SEO
robots.txt blocks all crawlers
Your robots.txt disallows the whole site for every crawler, so search engines are told to stay out.
No H1 headline
There is no <h1>, so neither visitors nor Google get a clear main headline.
Blocked from indexing
Google's crawler is blocked from indexing this page.
Title is short (4 characters)
Your title is only 4 characters: “Home”. 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 (245 characters)
Your meta description is 245 characters; Google truncates after about 160, so the end of your pitch is cut.
No social preview image
No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.
No XML sitemap
No XML sitemap at https://powerco.de/sitemap.xml, so Google discovers your pages only by following links.
5 links with vague text
5 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.
No X (Twitter) card tag
No twitter:card tag. X falls back to Open Graph, which is incomplete here.
41 internal links, 11 external
The homepage links to 41 pages on powerco.de and 11 external pages.
1 checks passed
Canonical URL set
The canonical URL is https://powerco.de/en.html.
AI search readiness
robots.txt blocks 6 AI answer engine crawlers
6 of 6Your robots.txt shuts out ChatGPT search (OAI-SearchBot), ChatGPT (ChatGPT-User), Claude search (Claude-SearchBot), Claude (Claude-User), Perplexity (PerplexityBot) and Perplexity (Perplexity-User). These fetch pages to answer people's questions and cite the source, so your site can't be quoted or linked in those answers.
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.
No llms.txt
There is no https://powerco.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.
Opted out of AI training for 5 crawlers
robots.txt blocks GPTBot, ClaudeBot, Google-Extended, Applebot-Extended and CCBot, which collect pages to train models. That's a legitimate choice and doesn't by itself stop the site appearing in AI answers.
1 checks passed
Text is in the HTML
Your server sends the page's text in the HTML (432 words), so crawlers that don't run JavaScript still read it.
Other pages
4 pages share 2 titles
/ and https://powerco.de/en.html all use the title “Home”, and 1 other title repeat too. Search engines can't tell which page to show for a search, so each competes with the others.
14 pages without a meta description
https://powerco.de/en/about-us.html, https://powerco.de/en/about-us/locations.html, https://powerco.de/en/about-us/locations/salzgitter--germany.html, https://powerco.de/en/about-us/locations/valencia--spain.html, https://powerco.de/en/about-us/locations/st--thomas--canada.html and https://powerco.de/en/about-us/standard-factory.html and 8 others have no meta description, so Google writes the search snippet from whatever text it finds.
9 pages without an H1
https://powerco.de/en.html, https://powerco.de/en/about-us/locations.html, https://powerco.de/en/about-us/locations/valencia--spain.html, https://powerco.de/en/about-us/locations/st--thomas--canada.html, https://powerco.de/en/about-us/vertical-integration.html and https://powerco.de/en/product.html and 3 others have no <h1> headline, so visitors and search engines get no clear main topic.

Content and conversion
Thin social proof
Social proof on the homepage: 1 testimonial or review block. Pairing it with named testimonials or customer logos makes it far more convincing.
No analytics detected
No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.
No direct contact details
No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.
About 483 words of copy
The homepage carries about 483 words of visible text.
4 checks passed
Clear next step on the first screen
On a phone, the first screen shows a clear next step: “LEARN MORE”.
4 calls to action

1 short form
A short form (1 field at most) is right on the homepage.
Risk reducer mentioned
A guarantee or risk reducer (money-back, free trial, no credit card or similar) is mentioned on the page.
Privacy and tracking
2 cookies set on arrival
2Opening the homepage sets 2 cookies (measured from a US location before any click).
4 other companies contacted
Loading the homepage contacts 4 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
2 checks passed
Consent tool: OneTrust
A consent management tool (OneTrust) loads with the page.
No known trackers before consent
No known advertising or analytics trackers load before a visitor clicks anything (measured from a US location before any click).
Security, domain, email and software versions
