How we work on GEO in Berkeley

The Census Bureau puts the population of Berkeley at 121,749 in 2024. It is the 53rd largest city in California. Nationally it ranks 240th among US cities by population. In California we cover 76 cities.

In a smaller city hardly anyone has worked on their presence in AI answers yet. The first company in each sector to do it often keeps the recommendation. Vértigo is based in Murcia, Spain, usually 9 hours ahead of Berkeley. We work with clients abroad by video call, in English. Nearby, we also cover Oakland, Richmond and San Francisco.

How people ask AI in Berkeley

  • Renovation companies

    Before asking for a quote, many people ask AI what a renovation costs and who to call. We publish your guide prices and your finished jobs so it has something to work with.

  • Real estate agencies

    AI gets asked about neighborhoods, prices and agencies people can trust. Good area guides, written with your own data, make you a source it can quote.

  • Veterinary clinics

    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 Berkeley.

Our GEO work for businesses in Berkeley, part by part

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.

  1. 01

    AI visibility audit

    We ask ChatGPT, Gemini, Perplexity and Google what your customer would ask, and we measure if you appear, how you are described and who gets recommended in your place.

  2. 02

    Question research

    We find out what your customers really ask AI about what you sell, in your city, nationwide or abroad.

  3. 03

    Content AI can cite

    We rewrite your key pages with clear answers, your own data and a structure that engines can read and use as a source.

  4. 04

    Structured data and brand

    We make it clear who you are, what you do and where. It sounds minor, but it is the most common fault when an assistant describes a company badly.

  5. 05

    Mentions in the sources AI consults

    We look at which pages each assistant cites when it answers about your sector and work to get your company onto them.

  6. 06

    Tracking mentions and citations

    Month by month we track which answers you appear in, which links cite you and what visits and inquiries arrive from AI.

What it takes to be named by AI

Try it yourself. Ask ChatGPT about a kitchen renovation company in Berkeley and it will give you a handful of names. The same happens with a real estate agency in Berkeley. If you are not on that short list, you are not in the running.

  1. We ask each assistant about your sector and save the answers.
  2. We rewrite the pages that should answer those questions.
  3. We make your company details match on your website and your profiles.
  4. We work to get the press and listings in your sector to cite you.

Illustrative simulation. AI answers change every time a question is asked and nobody can guarantee a specific recommendation.

From the first analysis to the first mention

  1. 01

    Starting picture

    We put your customer's questions to each assistant and save the answers.

  2. 02

    Status report

    You receive a document with the answers, the sources and the actions we propose, from most to least important.

  3. 03

    Content and sources

    We prepare the pages AI needs in order to talk about you and work on your presence in the places it consults.

  4. 04

    Follow-up

    AI answers change often. We keep watch and react when your brand moves up or down.

Frequently asked questions about GEO in Berkeley

Can't find your question? Write to us and we'll reply within 24 hours.

Talk to the team
How much does GEO cost in Berkeley?

There is no single fee. A brand that AI already talks about needs less work than one starting from nothing, and a crowded sector calls for more content and more mentions. After the audit we send you a fixed quote and you decide, with no obligation.

Does GEO work for a local business in Berkeley?

It does. For local questions, assistants draw heavily on map listings, review sites and neighborhood press, all things a business in Berkeley can improve. A national name is not required. Accurate details, recent reviews and pages that say plainly what you do and where are what count.

Can you do GEO for a business in Berkeley from Spain?

Yes. We are based in Murcia, Spain, and work with clients abroad remotely, in English, by video call. You do not need to be in a place to ask AI about its businesses. Each month you receive the report with the answers and the tasks completed.

What happens if AI says something false about my company?

It can be corrected, though not overnight. AI repeats what it finds, so the source of the error has to be fixed and the correct fact reinforced on your website and your profiles. With assistants that answer from training, the old version can linger until the model is updated.

Do I need SEO for GEO to work?

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.

Is GEO the same as AI SEO or AEO?

More or less. GEO, AI SEO, AI search optimization and AEO (answer engine optimization) are names for the same aim: being cited and recommended in answers written by AI. The industry has not settled on one term. We say GEO, but the work is identical whatever you call it.
