Search is shifting from keywords to intent.
Why invest in GEO?
Answers are generated by language models. Whoever gets named in that answer wins; whoever is left out effectively no longer exists. The numbers show how fast this shift is happening:
900M+ weekly users rely on ChatGPT for questions they used to ask Google.
47% fewer click-throughs with AI Overviews. On a Google page with an AI Overview, only ~8% click through to an organic result, versus ~15% without.
−50% organic search traffic by 2028, as users switch to generative AI search engines.
Up to +40% more citations in AI answers with the right GEO tactics, demonstrated in peer-reviewed research.
Why a GEO agency?
Improving your visibility in AI search requires knowing what AI models say about you right now, why they say it, and how to steer that on an ongoing basis, across six models that change every month.
You have no view of where you do and don't appear
01
AI answers come with no ranking overview and no Search Console. You don't know which questions you're named for, in which models, or with what message, and therefore you don't know what could be better. We make that visibility measurable.
AI misrepresents your brand
02
Models summarize based on sources you don't control, and in doing so pull in outdated, incomplete, or simply incorrect information. One wrong claim gets repeated to thousands of users. We track it down and correct the underlying sources.
Your competitor shows up more often, and more favorably
03
Ask an AI assistant for the best option in your category and out comes a shortlist. If you're not on it, or you're less convincing than your competitor, you lose the deal before the buyer ever visits your site. We make sure you show up positively in that recommendation.

What we learned about AI search this week
Weekly Insights
This week in AI Search: AI Overviews on 83% of brand searches, the median AI citation halves in 11 days, Gemini tags its links, Shopify opts shops in.
This week in AI Search: links return to AI Overviews, some lead into AI Mode, Google auto-enables checkout in AI Mode, ChatGPT falls to 50% of prompts.
Our DMEXCO 2026 recap: a fully booked ChatGPT Ads masterclass with the first European numbers, our first booth, and plans for 2027.
B2B and SaaS
Where buyers research and compare on their own via search engines and AI assistants before requesting a demo or getting in touch.
Financial, legal, and medical service providers
Where a mention or recommendation from an AI tool carries more weight, because clients select on trustworthiness.
Large consumer brands
That are noticeably losing traffic and search volume to Google AI Overviews and ChatGPT, and want to stay visible there.
E-commerce
With product catalogs that, in the coming years, will increasingly be compared and selected by AI agents rather than by people on a classic product page.
Marketing and communications agencies
That want to bring GEO expertise in-house to strengthen their advisory work.
