SEOnautik is an automated audit for SEO and AI visibility (GEO), built for small and mid-sized businesses in Germany, Austria and Switzerland. Instead of a monthly tool subscription, it delivers a one-off report with 89 checks: up to 50 pages (Pro: up to 500) are checked for technical SEO, on-page content, page speed, legal basics such as Impressum and privacy policy, and AI-crawler access, llms.txt and entity signals. Whether Google Fonts, trackers or embedded services load before consent is measured in a real browser.
In the AI-visibility check, 8 to 10 realistic customer questions derived from the site's own content are asked to ChatGPT, Claude, Perplexity and Gemini with live web search. For every question and engine, the report shows whether the brand is named or the domain is cited, and which other websites and directories the engines cite instead. The result is a prioritised to-do list with fix guides, as web report and PDF, delivered by e-mail in about five minutes.
AI answers vary from day to day, so the report shows the raw answers; there are no ranking guarantees. The method, with all checks, weights and thresholds, is public. Free tools need no sign-up: AI-crawler check, Google Fonts check, Impressum check and a 30-second quick check. Pricing: SEO check 29 EUR, AI-visibility check 59 EUR, Pro 129 EUR (one-off, incl. VAT); optional monthly monitoring 29 EUR per month. The product and report are in German.
