SEOnautik - 2026 Pricing, Features, Reviews & Alternatives

SEOnautik is a cloud-based website analysis tool that measures how visible a business's website is to AI assistants and search engines. Hosted on servers in Germany, it requires no account or login for its free quick check, which returns initial results in approximately 30 seconds. The full audit submits 8 to 10 realistic customer questions, derived from the website's own content, to the official APIs of ChatGPT, Claude, Perplexity, and Gemini with live web search active. It then measures citation and mention rates per question and per AI system, identifies which competitors the AI systems recommend instead, and checks AI crawler access via robots.txt and the presence of an llms.txt file. Beyond AI visibility (GEO), SEOnautik evaluates 89 checkpoints across five additional domains: technical SEO (24 checkpoints covering HTTPS, redirects, SSL, robots.txt, sitemap, canonical URLs, mobile rendering, and broken links), on-page content (20 checkpoints covering titles, meta descriptions, headings, image alt texts, structured data, and Open Graph), page speed (11 checkpoints covering Google PageSpeed scores, Core Web Vitals, and server response time), trust and visibility (10 checkpoints covering schema markup, Google Business Profile, Wikidata, and contact data consistency), and legal compliance for the DACH region (6 checkpoints covering Impressum, privacy policy, and browser-measured detection of Google Fonts, trackers, and embedded third-party services loading without consent).

SEOnautik delivers output as a prioritized action list with step-by-step instructions rather than a score alone. Reports are accessible via web interface and PDF for 12 months. Pricing is one-time with no subscription required, except for an optional monthly monitoring tier that tracks score history and sends deterioration alerts. A Pro tier adds an implementation plan with timeline and responsibilities, ready-made briefings for web designers and hosters, crawling of up to 500 pages, and keyword rankings for up to 10 terms on Google Germany (top 30). The methodology, all 89 checkpoints, weights, and thresholds are publicly documented. The tool is designed for small and medium-sized businesses in Germany, Austria, and Switzerland, with explicitly referenced verticals including tax advisors, lawyers, dentists, tradespeople, real estate agents, and hotels. Web agencies and partners managing multiple client websites are also supported.
