warning Thin content (low word count)
Rule content.thin · Content · 3 occurrence(s)
- https://balder-app.ch/ — 63 words
- https://balder-app.ch/ai/chatbot-demo.html — 6 words
- https://balder-app.ch/en/home/ — 58 words

warning Missing <h1>
Rule h1.missing · Headings · 2 occurrence(s)
warning Content-Type header doesn't match the actual content
Rule headers.content_type_mismatch · Security · 1 occurrence(s)
- https://balder-app.ch/ai/chatbot-demo.html — the Content-Type is "text/html" with no charset — the HTTP charset is authoritative and browsers otherwise guess the encoding, which can garble non-ASCII text (mojibake). Declare it explicitly: "text/html; charset=utf-8".
warning Orphan page (no internal inlinks)
Rule links.orphan · Links · 1 occurrence(s)
- https://balder-app.ch/ai/chatbot-demo.html — no internal links point here

Rule meta_desc.missing · Meta Description · 6 occurrence(s)
warning Render-blocking script in <head> (no defer/async)
Rule perf.render_blocking · Performance · 5 occurrence(s)
- https://balder-app.ch/ — 2 render-blocking <script> in <head> (add defer/async or use type=module)

warning Content only rendered by JavaScript (invisible to non-JS crawlers & AI)
Rule rendering.js_shell · Rendering · 1 occurrence(s)
- https://balder-app.ch/ai/chatbot-demo.html — Raw HTML has 6 words and 0 links — this page is built by JavaScript in the browser. Googlebot renders JS but delays it, and most crawlers and AI assistants (ChatGPT, Perplexity, Claude) don't run JavaScript at all, so to them the page looks empty. Server-render or pre-render your main content and navigation.

notice Low text-to-HTML ratio
Rule content.low_ratio · Content · 3 occurrence(s)
notice Main text is hard to read (low Flesch Reading Ease)
Rule content.readability_poor · Content · 1 occurrence(s)
- https://balder-app.ch/en/mobile-apps-in-switzerland/ — this page reads as very difficult (Flesch Reading Ease -101, below 50) — long sentences and multi-syllable words make it hard to scan. Shorten sentences and prefer plainer words to widen your audience. Density can be legitimate for expert, technical or legal content, so judge it against who the page is for.
notice Image filename is generic/auto-generated (missed image-search signal)
Rule images.generic_filename · Images · 4 occurrence(s)
- https://balder-app.ch/ — 2 image(s) use a generic/auto-generated filename (e.g. IMG_1234.jpg, photo1.png, a bare UUID). Google reads the filename as a signal of image content, so rename files descriptively (hyphen-separated words) before upload.

notice Likely hero image lacks fetchpriority=high
Rule images.hero_no_fetchpriority · Performance · 5 occurrence(s)

notice No Last-Modified header (no conditional GET for unchanged pages)
Rule perf.no_last_modified · Performance · 5 occurrence(s)
