What we measure when we do GEO in Dunedin
Here the result can be counted: how many times AI names your brand and how high up in the answer.
More than 200 clients trust us.
GEO, short for generative engine optimisation, is the work of getting AI assistants to name your company in their answers. We do it for businesses in Dunedin, so that ChatGPT, Gemini, Perplexity and Google mention you when someone asks about what you sell.

ways an assistant can answer: by searching the web at that moment or from what it learned months ago. We work on both.

DunedinNew ZealandWorldwide
The population of Dunedin is about 130,000. It is part of the Otago region.
For smaller cities AI often has little to go on and ends up recommending companies from the nearest big city. Giving it well-organised information is how you get it to name you instead. Vértigo is based in Murcia, Spain, 10 to 12 hours behind Dunedin. We work with clients abroad by video call, in English. The same service is available in Invercargill, Christchurch and Nelson.

GEO, sector by sector
When someone asks ChatGPT for a dentist they can trust in Dunedin, the answer comes from reviews, health directories and your own website. We put all three in order.
Owners ask AI about symptoms and about clinics that are open. With hours, services and reviews kept up to date, your clinic has a better chance of appearing in the answer in Dunedin.
More and more visitors ask AI to plan where to eat. What it says comes from reviews, guides and local press, and that is where you need to appear.

Most of this work happens outside the chat window. An assistant builds its answer from web pages, reviews, listings and press, so we look at what it finds about you in each of those and fix what is missing or wrong.
Dozens of real questions from your sector, put to each engine. The result is a table showing where you appear and, where you do not, which competitors are there instead.
We collect the doubts your customer settles before buying: prices, comparisons, who to go to. Those are the questions you want to appear in.
We create the pages that are missing: guide prices, comparisons, frequently asked questions. That is the material answers are made from.
We mark up your website with structured data and bring your Google Business Profile and other listings up to date, since that is where engines get the basics.
AI recommends whoever it sees recommended. We aim to get you into the articles, lists and publications it uses as references in your sector.
We repeat the same questions every month and compare. That way you see, with screenshots, which answers you have won and which are still pending.
More and more people ask AI before they search. It makes no difference if the question is about a dentist in Dunedin, a gaming laptop or luggage storage in Auckland. AI names a few companies and the rest go unmentioned.
Illustrative simulation. AI answers change every time a question is asked and nobody can guarantee a specific recommendation.
We put your customer's questions to each assistant and save the answers.
We compare what AI says with your website and with the sources it cites. You get it in writing: what is missing and where to begin.
We rewrite pages, put your brand data in order and seek mentions in reliable sources. Whatever carries most weight goes first.
We review mentions, links and visits from AI, and decide the next step with you.

Talk to the teamWe do not publish prices because two projects are rarely alike. The cost follows the number of questions you want to appear in, the state of your website and how well known your brand already is. You get a written quote after the first review and can say no.
No. AI answers change from one run to the next and nobody outside controls them. What we do is raise the number of times you appear and prove it to you with the saved answers from each month, set next to the earlier ones.
ChatGPT, Gemini, Perplexity and the AI results Google shows above its listings. Those four are our standard set. If another assistant matters in your sector, such as Microsoft Copilot, we add it to the tracking and report on it with the rest.
Yes. Visits that come from ChatGPT, Perplexity or Gemini can be separated out in your website analytics. We show them to you each month alongside the mentions, so you can see whether being named is turning into visits and enquiries.
It happens more often than you would think. We look for where it got the wrong detail, correct it at the source and publish the right information in a way that leaves no room for doubt. Then we keep asking until the answer changes.
It is not compulsory, but it shows. If your website does not appear in search engines, assistants that read the web live have a hard time finding you. A site with sound SEO gives GEO something to build on, and we handle both in the same team.
We analyse what AI says today about your company and your competitors, at local, national or international level. You receive a report with the actions for your brand in order of priority.
