A Generative Engine Optimisation (GEO) agency helps your brand become the answer that large language models provide when your customers ask questions. Unlike traditional search agencies that focus on rankings in a list, a GEO agency engineers your content, entity signals, and citation authority so that ChatGPT, Perplexity, Google AI Overviews, and Gemini actively recommend your business.

The data is clear: AI search is no longer emerging — it's dominant. ChatGPT alone has 900 million weekly active users (OpenAI, February 2026). Google AI Overviews now appear in 18% of all searches and reach 2 billion users (Google, 2025). Perplexity processes 35–45 million queries daily (Perplexity, 2025).
When your potential customers ask these AI platforms for recommendations in your category, the AI either names your brand or it doesn't. There is no "page 2" in AI search — you're either cited or invisible.
Brands cited in Google AI Overviews earn 35% more organic clicks, while brands absent from AI answers see their organic CTR drop by 61% (Seer Interactive, 2025).
AI-referred traffic converts at approximately 6x the rate of non-branded organic search traffic (Webflow, 2025).
Research from the Princeton/Allen Institute found that semantic completeness has a 0.87 correlation with AI citations (GEO Research, 2024). A GEO agency audits every key page for topic coverage gaps, ensuring your content comprehensively addresses the questions AI models are trained to answer.
AI models validate claims by cross-referencing multiple sources. A GEO agency builds your brand's presence across the platforms that LLMs trust: industry publications, knowledge bases like Crunchbase and Wikidata, review platforms like G2 and Capterra, and high-authority editorial sites.
Large language models don't just index web pages. They build internal representations of entities — brands, people, products, concepts. A GEO agency ensures your entity signals are consistent and strong: structured data, knowledge graph presence, consistent NAP data, and clear entity relationships.
Each AI platform retrieves and ranks content differently. ChatGPT (commanding 60.7% market share) favours encyclopaedic depth. Perplexity weights content freshness. Google AI Overviews draw heavily from pages already ranking in the traditional top 10.
GEO isn't a one-off project. A GEO agency tracks your citation rate, monitors competitor visibility, and iterates strategy based on real citation data across all platforms.
growthvibe is an AI-native growth consultancy — not a traditional search agency offering GEO as an add-on. Our methodology:
A GEO agency specialises in making your brand visible inside AI-generated responses. This includes optimising how AI platforms like ChatGPT, Perplexity, and Google AI Overviews discover, evaluate, and cite your content. GEO combines content strategy, structured data, entity building, and citation authority.
Traditional search agencies focus on keyword rankings and backlinks. A GEO agency focuses on citation rate — how often AI platforms mention and recommend your brand. The signals are different: entity authority, semantic completeness, content freshness, and cross-source validation.
Most clients see measurable changes in AI citation visibility within 60–90 days. This includes increased brand mentions in ChatGPT and Perplexity responses, improved positioning in Google AI Overviews, and growing AI referral traffic.
We start with a comprehensive AI Visibility Audit. From there, we implement technical, content, and entity optimisation in priority order, measuring impact through monthly citation rate tracking.
Technical and content changes typically improve AI citation within 60–90 days. Entity authority building compounds over 3–6 months. We measure progress monthly.
