03 · Wichtigste Probleme

Es werden die wichtigsten 10 Probleme angezeigt. Das vollständige Audit mit Korrekturen auf Code-Ebene ist im kostenlosen Plan verfügbar.

  • 01
    WARN · technical
    Robots.txt
    The robots.txt file was found but does not contain a Sitemap directive. The Sitemap directive helps search engine crawlers discover all pages on your website more efficiently.
  • 02
    FAIL · onpage
    Meta Description
    The meta description is missing. Google + Bing + Yandex will fabricate a SERP snippet from random page text — often ending mid-sentence or surfacing irrelevant content. ChatGPT / Claude / Perplexity may quote the description verbatim as a citation snippet; without one, they fall back to less benefit-focused page text. Missing description = lost CTR even when ranking is unchanged.
  • 03
    FAIL · content
    Thin Content
    Thin content detected on this page — only 91 words. Text-to-HTML ratio: 9.8%. Search engines (Google, Bing) demote pages with insufficient unique content in their rankings.
  • 04
    FAIL · onpage
    HTML <head> completeness
    1 essential head element(s) missing: Meta description. 9 recommended head element(s) missing: html lang attribute, Open Graph title, Open Graph description, ....
  • 05
    FAIL · onpage
    Content Length
    Only 91 words were found on the page. This is extremely low for proper indexing. Pages with minimal text content (fewer than 100 words) are considered "thin content" by search engines and rank poorly.
  • 06
    WARN · security
    Security Headers
    Found 5 out of 6 modern security headers. Missing: permissions-policy. Add the remaining headers to close defense-in-depth gaps. Note: Content-Security-Policy is the highest-impact header — if it is missing the site is exposed to XSS even when other headers are present.
  • 07
    FAIL · content
    Keyword Stuffing
    Keyword stuffing detected. The following words appear excessively often: "zone" — 3 times (4.8%), "number" — 3 times (4.8%), "registries" — 3 times (4.8%), "protocol" — 3 times (4.8%), "management" — 2 times (3.2%), "root" — 2 times (3.2%), "assignments" — 2 times (3.2%), "int" — 2 times (3.2%), "arpa" — 2 times (3.2%), "database" — 2 times (3.2%), "registry" — 2 times (3.2%), "repository" — 2 times (3.2%), "internet" — 2 times (3.2%). The acceptable keyword density is 1-2%. Exceeding the 3% threshold may result in search engine penalties.
  • 08
    FAIL · ai-readiness
    Structured Data Completeness
    No structured data (JSON-LD / Schema.org) found. AI search engines rely heavily on structured data to understand and cite content. Without it, your pages are much less likely to appear in AI-generated answers.
  • 09
    FAIL · security
    Email Authentication (SPF / DMARC / DKIM)
    SPF: fail · DMARC: fail · DKIM: info. Missing or broken: SPF, DMARC. Without SPF/DKIM/DMARC, your emails are likely flagged as spam by Gmail/Outlook, and your domain can be spoofed by phishers.
  • 10
    WARN · ai-readiness
    Knowledge Panel Readiness
    Partial knowledge-panel readiness — score 50/100. Missing components: Organization JSON-LD with ≥5 sameAs anchors, visible NAP (name/address/phone). Each missing piece reduces the chance of appearing in Google Knowledge Panel and AI-search citation anchors.
