GEO for businesses in San Jose: how we count progress
We ask the same questions every month and write down, for each answer, if your company is in it, how high up and which source is cited.
More than 200 clients trust us.
GEO, short for generative engine optimization, is the work of getting AI assistants to name your company in their answers. We do it for businesses in San Jose, so that ChatGPT, Gemini, Perplexity and Google mention you when someone asks about what you sell.

San JoseUSAWorldwide
San Jose has 997,368 residents according to the US Census Bureau estimates for 2024, which makes it the third largest city in California. That puts it 12th in the national ranking of cities. We have pages for 76 cities in California.
In a city this size AI has plenty of companies to choose from, and it names only a few in each answer. Getting into that group takes content of your own and mentions in the press. We work from Murcia, in Spain, usually 9 hours ahead of San Jose. Meetings are by video call and in English. We offer the same in Santa Clara, Sunnyvale and Fremont.

GEO, sector by sector
Many people describe their case to an AI assistant before they call a firm. If your site explains each practice area clearly, you are easier to cite when the question is about San Jose.
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.
Trips are now planned by asking AI. Whether it names your hotel depends on what guides, reviews and your own website say about you.
We measure before we change anything. The starting picture shows the answers you appear in and, for the ones that leave you out, who is there in your place.
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.
We collect the doubts your customer settles before buying: prices, comparisons, who to go to. Those are the questions you want to appear in.
Fewer adjectives, more facts. We reorganise your website so that each page answers one specific question and answers it well.
Name, address, services and opening hours, the same everywhere. If every site says something different, AI hesitates and names someone else.
We work to get your brand talked about in the media, comparison articles and directories that engines draw their recommendations from.
A short monthly report: mentions, links, visits from AI and what we plan to do the following month.
Someone asking about an employment lawyer in San Jose or a real estate agency in San Jose does not get pages of results. They get a short reply with a few company names in it. The simulation here follows one company from absent to first recommendation.
Illustrative simulation. AI answers change every time a question is asked and nobody can guarantee a specific recommendation.
We check what each engine says today about your company and about your competitors.
We decide with you which questions to go after first and what has to change on the website to win them.
We rewrite pages, put your brand data in order and seek mentions in reliable sources. Whatever carries most weight goes first.
AI answers change often. We keep watch and react when your brand moves up or down.

Talk to the teamThink of it as SEO for answers instead of lists. A search engine shows a page of links and lets you choose. An AI assistant writes a reply and mentions a handful of companies in it. Generative engine optimization, GEO for short, is the work of getting your company into that reply.
It depends on the assistant. Those that read the web at the moment of answering pick up changes soon, sometimes in a few weeks. Those that answer from memory need a new version of the model. That is why we work on both routes at once.
It does. For local questions, assistants draw heavily on map listings, review sites and neighborhood press, all things a business in San Jose 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.
You rarely have to rebuild it. The usual work is rewriting some pages, adding the ones that are missing and marking up your data properly. We only propose a new website when the current one is hard for search engines and AI crawlers to read.
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.
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.
Tell us what you do and we will ask ChatGPT, Gemini, Perplexity and Google about you. We send you the answers and what we would do to improve them.
