Our generative engine optimization (GEO) services, also called AI search optimization, cover three areas: access for AI crawlers, answers to your customers’ questions and mentions beyond your website. Every month, our GEO retainer measures whether and how four AI systems mention you. These services are for companies with a website that AI answers leave out or get wrong.
A question from your customers
Search engine
10 links
AI assistant
one answer that names only a few providers and sources
If you’re not in those answers, fewer people see you, even when your website ranks well on Google
AI crawlers, which fetch pages for AI providers, can read your site. Content is in the HTML, not behind JavaScript, and your host doesn’t block them.
Your name, location, services and people, described the same way on your site and all your profiles.
Pages that answer your customers’ questions directly, with sources and dates. Our how-to Service pages for AI search shows how to build a service page.
Profiles and listings on the directories and portals that turn up as sources of AI answers when we measure for your business.
Every month: 25 questions across four AI systems, three runs each, and a report that includes drops.
We review the generative AI performance report in Google Search Console and AI citations in Bing Webmaster Tools.
Each column is one question
Each row is one run
Each square is one answer
ChatGPT search
Perplexity
Google AI Mode
Microsoft Copilot
15 × 4 × 3 = 180 answers
We put 15 of your customers’ questions to four AI systems, three times each. That’s 180 answers. We also review your technical setup and company facts, check your directory listings and deliver a prioritized action plan with a 60-minute review call.
At Datafalke, the AI visibility audit has a one-time price of €950 excl. VAT and is available to businesses and self-employed professionals.

We run a fixed list of customer questions through four AI systems, three times each. We count how often you’re mentioned and linked as a source, and we report drops, too. The four systems are ChatGPT search, Perplexity, Google AI Mode and Microsoft Copilot.
Each question runs three times because a single query proves little: answers from AI assistants can change from one query to the next. Even so, the measurement remains a sample. It isn’t a ranking, and signed-in users may see different answers. To run your own measurement, follow the steps in How to measure AI search visibility.
See the methodCompare GEO agencies on what you can check yourself: how they measure, who does the technical work and in whose name the profiles are set up. At Datafalke, the same team works on your website and your search visibility, and these four points apply to every GEO project.
A fixed set of questions, four AI systems, three runs each. We report drops as clearly as progress.
We fix technical barriers ourselves. GEO setup includes up to eight hours for this.
Every profile is set up in your name.
We don’t offer paid placements in “best agency” lists.
By video, or in person at your office if you’re in the Ruhr area of Germany. The call is free, and you talk directly to the engineer who will do the work.
We measure how AI systems describe you today and review your technical setup and company facts.
We work through the action plan from the audit.
Every month, we run the same questions again, monitor crawler access and indexing, and keep your profiles up to date.
We test whether AI assistants can read a website on our own site first. The sections below show how the site is built for AI search and how we check it.
All examples come from our own project, datafalke.de, not from client work.
Mohammad Alboush is a software engineer and the owner of Datafalke. He’s your direct line to the team, from the intro call to sign-off. He replies to requests within one business day (Monday to Friday).
The AI visibility audit has a fixed price and a fixed scope. We quote the fixed price for GEO setup and the retainer after the audit, and the factors that drive it are listed below the packages.

No one can guarantee a #1 ranking on Google.
Largely, yes. Google itself says (external site) that “optimizing for generative AI search is optimizing for the search experience, and thus still SEO.” GEO adds three things: consistent company facts across every channel, measurement with real questions in several AI systems, and mentions on other sites. AI systems also use sites like these as sources. You may also see this work called answer engine optimization (AEO) or AI SEO.
No. Nobody can guarantee rankings or mentions. Google says so itself (external site), and Bing says the same about citations in AI answers (external site). We commit to what we can deliver ourselves: written acceptance criteria, a fixed price after a short analysis, and monthly measurement that also shows drops.
That depends on where you’re starting from, so we don’t promise a date. Technical improvements are documented in the test report at sign-off. In AI answers, we only count a change as a trend once it falls outside the range of our three runs and lasts two months. By our estimate, it therefore takes 3 to 6 months for the measurements to show a reliable change.
No measurable effect has been shown. An llms.txt file is a text file with pointers for AI systems. In May 2026, 97% of the llms.txt files studied were never fetched, and Google’s own guidance (external site) says Google Search doesn’t use such files. We set up a minimal one, but we don’t sell it as a tactic.

At Datafalke, the audit has a one-time price of €950 excl. VAT. You get 180 answers from four AI systems, a technical and entity review, a directory listing check, a prioritized action plan and a 60-minute review call. If you go ahead with GEO setup or a website within the period listed under Packages, we credit the full audit fee.

It mainly depends on how many services, languages and locations you have, the technical state of your website and how much new content you need. The audit has a fixed price; for setup and the retainer, we quote a fixed price after the audit. Our cost guide How much does generative engine optimization (GEO) cost? compares market prices and cost drivers.
Yes. We’re based in Bottrop, Germany. We work remotely across Germany and the EU, and in person in the Ruhr area. We work with companies from other EU countries in English or German. Our focus remains the German market. Our page SEO and GEO for Germany explains how we help international companies reach German buyers.
No. In Germany, paid placements count as advertising and must be labeled. We work with directory profiles, genuine reviews and expert articles. Our how-to on choosing a GEO agency shows how to spot reputable providers.
Not necessarily. If you already have a website, we start with an audit. Our AI visibility audit includes a technical SEO review of the essentials and shows how AI systems see you. Then you decide whether fixes are enough or a rebuild makes more sense.
