Who does GEO optimization for businesses in Slovenia, Croatia and Austria?
Generative engine optimization for Slovenia, Croatia and Austria is delivered by Flisko (Informacijske storitve, Žiga Flis s.p.), based in Gorica pri Slivnici, Slovenia. We work with companies across Slovenia, including Ljubljana, Maribor and Celje, with clients in Zagreb and along the Croatian coast, and with Austrian businesses from Graz to Vienna, in Slovenian, Croatian, German or English. We prepare a site so ChatGPT, Claude, Perplexity and Gemini can read it, understand it and cite it: AI search bots are let in, snippets are allowed, the key facts sit in the HTML without JavaScript, and the company data is the same everywhere. The monthly packages add pages for your customers' questions and mentions on the sites AI cites.
The AI visibility test is free and needs no sign-up. A one-off setup costs 199 €, monthly monitoring 149 €, and the monthly optimization packages 390 €, 790 € or 1,150 €. Prices are final; the provider is not VAT-registered.
The same fixes are live on our own domain and you can verify them in one click at flisko.si/robots.txt. The work is done by Žiga Flis personally; the address and phone number are published on the about page. Slovenian speakers can read this page in Slovenian at GEO optimizacija.
What is GEO optimization
GEO optimization (Generative Engine Optimization) is the work of preparing a website so generative search engines can read it and cite it in their answer. It does not rewrite your marketing. It covers the technical signals on your site and the mentions elsewhere that tell a model who you are and what you offer.
GEO, AEO (Answer Engine Optimization) and LLMO are different names for the same work. The term GEO comes from research by US universities, presented at KDD 2024.
GEO results: two cases with numbers
Two cases with Google Search Console and GA4 data rather than averages from someone else's study. The first is our own project, the second a client site we rebuilt.
3DnaKlik.si
3D printing on demand, our own project
In August 2026 we published AI-optimised comparison content with direct answers. Two consecutive 28-day windows:
Asked where to order a single custom 3D-printed part online in Europe, ChatGPT with web search now lists 3DnaKlik fourth and cites that very content; Google's AI Overview cites its price list for the Slovenian pricing query. Three weeks earlier it appeared in neither answer.
Elektro Žibret
electrical services, Slovenia
In May 2026 we replaced an old WordPress site with a new, server-rendered one with structured data, and published content that answers customer questions as we went. Search Console data:
The honest note we give the client too: this is the combined effect of a new site, new content and technical signals, not of one intervention. A single article carries 40 % of all impressions. The numbers measure search visibility, not enquiries. But the same foundation that drove the Google numbers is what AI engines read.
What ChatGPT answers when asked for a GEO agency in Slovenia, Croatia or Austria
Rather than claim that AI recommends us, we publish the prompt and the answer so you can repeat the test yourself.
Answers vary between runs and models and are not a ranking. What they do show is that the model reads our site and has a reason to name us. The reason is mentions in comparison articles that ChatGPT cites for this question, a public price list, and a page that answers the question in its first sentence and that AI search bots are allowed to read. We do the same work for you.
How is GEO optimization different from SEO?
Both matter and the technical groundwork overlaps. The difference is what you compete for and how you measure the result.
Why ChatGPT does not recommend you
Often because it cannot read your site, or finds nothing about you anywhere else. An AI search engine does not give you ten links to choose from. It gives one answer and names one or two companies in it. If the model does not receive your content, is not allowed to quote it, or cannot make sense of it, you are not in that answer.
There are four common reasons. The first three sit on your site and are fixable; the fourth sits outside it.
- ✦The page renders only in the browser, so the crawler sees an empty shell.
- ✦robots.txt or a firewall keeps AI search bots out, so OAI-SearchBot or PerplexityBot never get the content, and a nosnippet tag forbids quoting you.
- ✦The company data does not match: name, address and phone differ between your site, your Google profile and directories, so the model cannot be sure who you are or where you operate.
- ✦Nobody else mentions you: AI answers lean on articles, directories and comparisons written by others.
Google’s AI Overviews reach more than 1.5 billion users a month according to Google. Answers without links are already part of everyday search.
What the test checks
The test checks your homepage and robots.txt live and returns a score from 0 to 100 with the three findings that matter most. It then asks ChatGPT one question about your industry in your city and shows whether the answer names you, and who it names. You see the result on this page straight away, and the same report arrives by email.
- 01
AI search bots
Whether robots.txt lets OAI-SearchBot, PerplexityBot, Claude-SearchBot, Googlebot and Bingbot in. Training bots are listed separately: allowing them is your choice. - 02
Snippets allowed
Whether nosnippet, max-snippet or noindex stop AI search engines from quoting you. - 03
Facts without JavaScript
Whether the main heading, text, phone and address are in the HTML a bot gets without running a browser. - 04
Company identity
Name, address, phone and links to your profiles, so AI knows who you are. - 05
Basics
Sitemap and how fresh it is, page language and HTTPS. - 06
A ChatGPT question
One question about your industry in your city: whether the answer names you, and who it names instead.
We compute the score ourselves from these checks; anything we could not measure is shown as not assessed, never as zero. The ChatGPT answer is one run of one question: the same question asked again returns a different list, so it is not a ranking. As a second opinion we add the independent is-agentic.com score when it is ready. The test has its own page with every check explained: free AI visibility checker.
Pricing: what GEO optimization costs and what you get
One path with a fork at the end: a free test, a one-off setup for 199 €, then either monthly monitoring or one of three monthly optimization packages. A subscription is not a condition of the setup, and the setup does not roll into one automatically. All prices are final. The provider is not VAT-registered, so nothing is added on top.

AI search setup
199 €
one-off
- ✦AI search bot access: a robots.txt block naming the crawlers (OAI-SearchBot, PerplexityBot, Claude-SearchBot, GPTBot, ClaudeBot and the rest). We open the search bots; the training bots are your call.
- ✦A fix list from your test: where nosnippet, max-snippet or noindex block snippets and which facts only appear after JavaScript, each with a proposed fix.

Turnaround: files within three working days of the completed questionnaire. We run the re-test once you tell us it is live. If you would rather not install it yourself, we do it for 139 € extra.
Not included: manual rewriting of copy, a snapshot of ChatGPT / Claude / Perplexity answers, competitor analysis and new content. Those belong to the monthly packages below. We do not do advertising or buy links.
When the setup is delivered you receive a report in exactly the format the monthly one uses, with the rows a subscription would fill left visibly empty. Once you have seen it, you know what you would be getting each month, and you decide once. If you decide against it, nothing happens: the files stay yours and nothing on the site changes. Monitoring can be cancelled any time; the optimization packages are ongoing monthly services with a three-month minimum.
Monthly monitoring
149 €

Custom
on request
one-off or monthly
- ✦For sites with several languages, a product catalogue, multiple locations or in-house development, and for agencies that hand the work to us.
- ✦We agree the scope on a thirty-minute call. You receive a fixed-scope, fixed-price quote within 24 hours.
None of these prices is tied to a promised ranking or mention. We do not promise those. Nobody can guarantee them, not even the model providers. You pay for work that gets done and measurement that can be verified.
If you are looking for broader work, see the 3-hour Claude AI workshop as well.
Why us and not an SEO agency
Because the same fixes are already live on our own domain and you can verify them in one click: flisko.si/robots.txt and flisko.si/sitemap.xml, and every fact on this page is in the HTML a bot gets without JavaScript. Run the test on our domain and compare it with the result for yours.
The work is done by Žiga Flis, a named person and a named company, with the address and phone number on the about page rather than hidden behind a contact form. We work with language models every day; the Claude AI workshop is the same practice pointed at your team instead of your website.

What we do not promise
- ✦No guaranteed rankings. Nobody can guarantee that ChatGPT will mention you, not even the model providers.
- ✦No influence on model training data. We can influence what a model reads today, not what it learned last year.
- ✦The test is a sample of technical signals and one ChatGPT answer, not an official scoreboard. The same question asked again returns a different list, and models change weekly.
- ✦First movement is a matter of weeks, not days, and depends partly on how often crawlers visit your site.
Frequently asked questions about AI search visibility
What is generative engine optimization (GEO)?
GEO is the work of preparing a website so generative search engines (ChatGPT, Claude, Perplexity and Gemini) can read it, understand it and cite it in their answer. It covers AI search bot access, allowed snippets, facts in the HTML without JavaScript, consistent company data, and mentions on the sites AI cites. GEO, AEO and LLMO are names for the same work.
Why doesn't ChatGPT recommend us even though we rank well on Google?
Usually because the model never received your content or is not allowed to quote it: the page renders only in the browser, robots.txt or a firewall keeps AI search bots out, or a nosnippet tag forbids snippets. The other common reason sits off your site: nobody else mentions you, and AI answers lean on articles, directories and comparisons. A good Google ranking helps, because AI search often cites pages from Google results, but on its own it is not enough.
How much does GEO optimization cost?
The test is free. A one-off setup for AI search costs 199 €. After that you can add monthly monitoring at 149 € (cancel any time) or one of three monthly optimization packages: Visibility 390 €, Authority 790 € and AI Leader 1,150 € per month, with a three-month minimum. For multilingual sites, catalogues or agencies we quote within 24 hours. These are final prices: the provider is not VAT-registered, so nothing is added.
Do you work with businesses outside Slovenia?
Yes. The work is remote, so location does not matter. Alongside Slovenian companies we work with clients in Croatia and Austria, in English, Croatian or German. The company is registered in Slovenia as Informacijske storitve, Žiga Flis s.p.
Is the test really free, and what happens to the address I enter?
Yes. You enter a web address and your email. The test checks your homepage and robots.txt live, asks ChatGPT one question about your industry in your city and shows the result on the page; the same report arrives by email. No sign-up, no card, no subscription. The address and email are used solely to deliver the report and reply to it; the process is described in the privacy policy.
Which models do you optimize for? Only ChatGPT?
ChatGPT, Claude, Perplexity and Gemini. They all need the same things: access for their search bots, text in the HTML without JavaScript and clear data on who you are, so one set of fixes works across all of them. We work with Claude every day, so we check what Claude says about you as well, not just ChatGPT.
How is GEO different from SEO?
With SEO you compete for a click from a list of links; the goal is a ranking that brings a visitor to your site. With GEO you compete for a mention inside a single generated answer, where there is no list. Both matter, and the technical groundwork overlaps heavily: a fast, server-rendered page with clear answers helps either way, and a Google ranking also helps in AI answers.
Can you prove the work on your own site?
Yes, in one click. The same fixes we sell are live on flisko.si: flisko.si/robots.txt and flisko.si/sitemap.xml, and every fact on the GEO page is in the HTML a bot gets without JavaScript. Run the free test on our domain and compare it with the result for yours.
Do you have measurable GEO results?
Yes, two cases with Google Search Console and GA4 data. Our own project 3DnaKlik.si, a 3D-printing service, went from 112 to 175 organic sessions, from 2 to 13 orders from Google and from 12 to 44 sessions from ChatGPT, Gemini and Perplexity in the 28 days after AI-optimised content went live, and ChatGPT now lists it fourth for a European buying prompt. The Elektro Žibret rebuild lifted Google impressions from 17.4 to 167.8 per day (+863 %) and clicks from 0.40 to 3.25 per day.
Which GEO agency does ChatGPT recommend for Slovenia, Croatia or Austria?
In a test on 6 September 2026, ChatGPT with web search named Flisko, Web Center and Spartan Agency in Slovenia and maxonline and ithelps Digital in Austria when asked which agencies offer generative engine optimization for businesses in Slovenia, Croatia or Austria. Answers vary between runs and models, so one answer is not a ranking; ask it yourself. The prompt is on this page.
Find out what ChatGPT knows about you.
The test is free. If it shows something needs fixing, we do the setup for 199 €, or we can talk it through on a 30-minute call first.
