AI search optimisation · GEO
We are Balisk.
We specialise in how AI tools crawl, choose and cite. We diagnose, implement and keep up to date what AI knows about your business.
Balisk is a company specialised in AI search optimisation (GEO) and technical SEO. We audit how AI systems (ChatGPT, Google, Gemini, Perplexity and Copilot) crawl and index a business. We measure how ChatGPT, Google’s AI Overviews and AI Mode, and Gemini cite it. We apply the changes on its website and beyond, and maintain them with monthly monitoring.
Specialists in AI answers.
We work on what decides whether an AI names you: crawling, indexes, sources and your business data.
- Crawling
- Indexing
- Rendering
- Structured data
- Entity
- Sources
- Measurement
We do it and maintain it.
We do not stop at a report. We apply every change, check that it works and monitor it every month.
Who we are, in detail.
-
What is GEO?
Getting AI to find you and cite you well.
GEO (Generative Engine Optimization) is the technical work of making the AI tools that answer questions able to crawl your website, find you in their searches, trust your data and cite you well. We mean ChatGPT, Google’s AI Overviews and AI Mode, Gemini, Perplexity or Copilot. It starts from technical SEO and extends it to external sources and to the entity.
-
What sets us apart?
The whole chain, measured and applied.
- We audit all eight links of the citation chain, not just the content.
- We measure with statistics, AI by AI and with a margin, never with a stray screenshot.
- We apply the changes ourselves or verify them one by one, on your website and beyond.
-
What is it like to work with us?
Specialists and a portal.
We diagnose, apply and maintain, and you see every change in your portal. We reply to your messages within 2 working days at most and we publish nothing without your approval.
-
Which languages do we work in?
Four languages.
We work in Spanish, Catalan, English and French, and we measure in the languages your customers search in, because each AI answers differently depending on the language.
What we know, with sources.
Our method rests on the official documentation of each search engine and AI, on peer-reviewed studies and on industry studies, every figure with its date and its grade of evidence. We review each platform’s data every quarter.
- Official documentation From each search engine and AI: crawlers, indexes and search features.
- Peer-reviewed studies On how generative engines choose and cite sources.
- Industry studies With their sample, their date and their wording; no source, no figure.
Three commitments.
-
We measure, not promise
Every reading, with its 95% margin.
-
Everything in sight
Every change, with its date and its proof.
-
Sourced data
Primary source and date on every figure.
In Spain, almost 4 in 10 people already use generative AI.

What do we not do?
We do not promise rankings. We do not buy reviews or links. We do not use hidden text or concealed instructions for the AI. We do not invent data or publish anything in your name without your approval. If a figure has no source, we do not use it.
Which AI tools do you work with?
With the ones your customers use to get informed: ChatGPT, Google’s AI Overviews and AI Mode, Gemini, Perplexity and Copilot. For all of them we work on access, sources and your data, and we also check the crawlers of Claude, Meta and Apple. We measure your presence in the answers of ChatGPT, AI Overviews, AI Mode and Gemini; for Copilot, with the data from Bing Webmaster Tools.
Do you also do SEO?
Yes, technical SEO: crawling, indexing, rendering, structured data, architecture and languages. It is the foundation of GEO, because AI tools with search start from indexes such as Google’s and Bing’s.
