Best European GEO Software (Generative Engine Optimization)
GEO (Generative Engine Optimization) is the practice of tracking and improving how your brand appears inside AI-generated answers rather than in a list of blue links. It matters because a growing share of research now ends in ChatGPT, Perplexity or a Google AI Overview without a click ever reaching your site. Every tool below is built by a European company, and for each one we name the registered legal entity rather than asking you to take a country badge on trust.
Rankscale has the widest engine coverage on this list: 17+ generative engines including ChatGPT, Perplexity, Claude, Gemini, AI Overviews, DeepSeek, Grok, Copilot and Mistral, and pairs monitoring with page audits scored against 200+ AI-readiness factors. Citation analysis, showing which sources the engines quote when they mention you, is the part that tells you what to go and fix. One caveat worth knowing before you buy: the company is Austrian, but its own privacy policy puts the service on Google Cloud with the primary data centre in Iowa, USA, under Standard Contractual Clauses: European ownership, not European data residency.
Otterly.AI is the most accessible entry, starting around $29/month against triple that elsewhere, and it still covers seven engines including ChatGPT, Google AI Overviews, AI Mode, Gemini, Copilot, Perplexity and Claude. Prompt research to find the questions driving AI answers in your category is the standout feature, useful before you have any visibility to monitor.
Hikoo is the French option and the most structured of the group, splitting the job into four modules: an analyzer that scores how AI engines read your pages, prioritized content recommendations, mention and sentiment monitoring across nine engines, and a competitive share-of-voice map. Pricing runs €69–389/month, so it sits between the budget and enterprise ends of this list.
Superlines is the pick for teams that need the data somewhere other than a dashboard: alongside its UI it exposes an API and a Model Context Protocol server, so AI-visibility data can feed your own reporting or agents. The Finnish company collects from real AI search interfaces rather than APIs, which matters because API responses and what users actually see can differ.
Peec AI is the Berlin entry and the most focused: visibility, position and sentiment across ChatGPT, Perplexity and Gemini, with competitor benchmarking and unlimited seats. Fewer engines than the others here, but the reporting is aimed squarely at marketing teams and agencies who need something a client will actually read.
GEO is the practice of improving how your brand is represented inside AI-generated answers (ChatGPT, Perplexity, Gemini, Google AI Overviews) rather than in classic search results. Where SEO optimises for a ranking position, GEO optimises for being cited and described accurately in an answer the user reads instead of clicking through.
How is GEO different from SEO?
SEO targets a list of links and is measured in rankings and clicks. GEO targets a generated answer and is measured in mentions, citations, sentiment and share of voice against competitors. The two overlap (being crawlable and well-structured helps both) but a page can rank first in Google and never be cited by an AI engine.
Why choose a European GEO tool?
GEO tools ingest your brand data and often your content, so the same data-residency questions apply as for any other martech. A European vendor keeps that under EU jurisdiction and avoids the CLOUD Act exposure that comes with a US parent, regardless of where the servers sit.
Do these tools track Google AI Overviews?
Most do. Rankscale, Otterly.AI, Hikoo and Superlines all list Google AI Overviews among their tracked surfaces; several also cover Google's AI Mode. Peec AI currently focuses on ChatGPT, Perplexity and Gemini.
