Be the answer
Google AI Overviews, ChatGPT and Perplexity are changing how people discover brands. Gartner estimates that 25% of traditional search volume shifts to AI-generated answers by the end of 2026. Traditional SEO rankings are no longer enough, your brand must be cited in the answers that AI provides. iO measures where you stand, optimises your visibility and monitors your position continuously.
GEO scan as your starting point, measurable from day one, almost always enough insight for a long-term strategy

Content optimisation for citability, the answers that AI search engines want to use
GEO audit and baseline measurement
Before you can optimise, you need to know where you stand. iO conducts a complete GEO audit, an analysis of your content, technical structure and visibility in AI search engines, and presents findings as an action-oriented priority list.
LLM tracking and monitoring
Brand visibility in AI-generated answers changes constantly. iO builds an automated tracker that runs branded and unbranded prompts weekly across multiple LLMs, so you see the trend, not just a snapshot.
Technical GEO implementation
Structured data (Schema.org FAQPage, SameAs, llms.txt) is the most direct technical means to become citable by AI search engines. iO implements, tests and monitors these elements across your digital environment.
GEO content strategy
AI search engines cite content that is clear, authoritative and answer-focused. iO helps you adjust your content strategy, which pages to rewrite, which FAQ structures to add and how to build authority on topics that matter.
AI impact and attribution
How do AI Overviews influence your organic traffic, conversion rate and lead quality? iO measures that relationship and makes the impact visible, including conversion tracking for AI-generated leads via tools like Promptwatch and BigQuery.
Our approach to Generative Engine Optimisation
GEO is not SEO with a different name, it requires a different way of thinking about content, authority and technical structure. iO has a proven approach from measurement to optimisation to monitoring, built on real client data.
Measure before you optimise
Every GEO project starts with an audit and baseline measurement. The criteria for being cited are different from the criteria for ranking: structured data, semantic authority, machine-readable content architecture. Only when you know how visible your brand is in which AI search engines, for which search queries and in which languages, can you prioritise meaningfully. iO delivers that measurement as a grounded starting position, not as a one-time report. iO analysed GA4 data from more than 1,400 client websites in NL and BE. The findings: 182% growth in LLM traffic in the first half of 2025, ChatGPT responsible for 85% of all AI search traffic, and organic traffic 7.8% lower than 2024. That own data forms the basis of every GEO project, no external benchmark, but analysis across our own customer base.
Technical and content optimisation together
GEO works on two levels: technical citability (structured data, llms.txt, site architecture) and content authority (answer-focused content, depth, authoritative sources). Both are needed, strong technical foundation with weak content won't work, and vice versa.
Continuous monitoring that learns
AI search engines update their models, new competitors emerge and search behaviour shifts. iO keeps your GEO position up to date weekly via automated LLM tracking, so you act on trends, not surprises.
Why iO for GEO?
We have measured the impact of AI Overviews
Hypotheekwinkel lost 50% organic sessions after the launch of Google AI Overviews in June 2025. iO quantified that impact as one of the first agencies in Europe, that data is the foundation of our GEO approach, not a theory.
Continuous insight that leads to better decisions
Suzuki's weekly LLM tracker runs in production, 120-130 prompts per month across three AI search engines in NL and FR. What that delivers: continuous insight into how the brand appears in AI-generated answers, data-driven choices about which content gets priority, and a measurable basis to see whether optimisations have an effect. That infrastructure is available for any brand taking their GEO position seriously.
Technical implementation we execute ourselves
iO doesn't just advise on structured data and llms.txt, we implement, test and monitor it too. For Audi.be, De Heus and others, we've delivered GEO technical improvements live, not just recommended them.
GEO and SEO as an integrated strategy
GEO doesn't replace SEO, it complements it. iO manages both and ensures your traditional search position and your AI visibility reinforce each other, not compete for the same content resources.
Own dataset of 1,400+ client websites
iO is one of the few agencies in Europe with its own dataset on AI search traffic. We analysed GA4 data from more than 1,400 websites in NL and BE, and published the results. That data backs our GEO recommendations with evidence, not assumptions.
Tools and platforms
iO is technology-agnostic. The choice of GEO tools depends on your content environment, your monitoring needs and your technical infrastructure.
