Speed
Use efficient cache lifetimes
750 ms · 124 KiB8 files are served with short cache lifetimes, so returning visitors download them again (124 KiB).
Render-blocking requests
100 ms1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 100 ms.
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: 0.6 s

Core Web Vitals
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.

Images and page weight
About 0.04 g of CO₂ per visit
0.04 gBy the Sustainable Web Design model, a visit to your homepage emits about 0.04 g of CO₂e: 4.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
4 checks passed
Page weight: 134 KiB in 9 requests
134 KiBYour homepage downloads 134 KiB in 9 requests on a phone: fonts 70 KiB (2), scripts 43 KiB (4) and HTML 11 KiB (1). That is a lean page.
Images use modern formats
Every sizeable image is WebP, AVIF or SVG.
Images load when needed
Images below the first screen wait until the visitor scrolls to them.
Images are sized for phones
No image is downloaded at more than three times the size it is drawn on a phone.
Accessibility
25 text elements with low contrast
25 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.
2 checks passed
Every image has alt text
All 2 images in the HTML carry an alt attribute.
48 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 49 WCAG 2.2 A/AA and best-practice rules on the phone render: 48 passed and 1 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.
SEO
Title is long (83 characters)
Your title is 83 characters, so Google will cut it off around 60: “OpenSUN Systems – AI-udvikling, MCP og integrationer der giver dine systemer vinger”.
Meta description is long (268 characters)
Your meta description is 268 characters; Google truncates after about 160, so the end of your pitch is cut.
Structured data has 8 problems
Structured data found (FAQPage, Organization, ProfessionalService and SoftwareApplication) but with 8 problems, for example “SoftwareApplication: no offers (price) block”.
Only 4 internal links
The homepage links to only 4 pages on your own site, so visitors and crawlers find few routes into the rest of it.

Canonical URL set

AI search readiness
No llms.txt
There is no https://opensunsystems.com/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.
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.
Organization data: 5 of 6 facts
Your Organization JSON-LD gives name, url, logo, description and contact details; sameAs (social profiles) would complete it.
Text is in the HTML

Content and conversion

No map or directions link
