What is a GEO agency?

A GEO agency is a digital marketing agency that specialises in generative engine optimisation, the practice of optimising your website and brand presence so that generative AI platforms like ChatGPT, Google Gemini, and Perplexity cite and recommend your business when generating answers. Unlike traditional SEO agencies that focus on Google search rankings, GEO agencies focus on how large language models select, summarise, and attribute sources.

What is GEO vs SEO vs AEO?

SEO (Search Engine Optimisation) focuses on ranking in Google's traditional organic search results. AEO (Answer Engine Optimisation) focuses on appearing as the direct answer in featured snippets, knowledge panels, and voice search results. GEO (Generative Engine Optimisation) focuses specifically on getting cited by generative AI models like ChatGPT, Gemini, and Perplexity when they produce answers. SEO targets click-through from search listings, AEO targets direct answer placement, and GEO targets AI-generated citations. A modern strategy requires all three.

How much does a GEO agency cost?

GEO agency costs in Australia typically range from $1,500 to $6,000 per month depending on scope, competition, and the number of keywords being targeted. Brain Buddy AI's managed plans start at $1,990 per month and include GEO alongside SEO and AEO optimisation, plus a deployed AI chatbot agent worth up to $499 per month. All plans are month-to-month with no lock-in contracts.

GEO stands for Generative Engine Optimisation, the practice of optimising content for AI search engines like ChatGPT and Gemini. CEO stands for Chief Executive Officer, the highest-ranking executive in a company. The two are unrelated. GEO is a digital marketing discipline, while CEO is a corporate leadership role.

How does generative engine optimisation work?

Generative engine optimisation works by structuring your website content, schema markup, and entity signals in ways that large language models can easily parse and attribute. This includes implementing comprehensive structured data, creating authoritative content with clear source citations, building entity authority through knowledge graph signals, and ensuring your brand information is consistent across the web. GEO also involves monitoring which brands AI platforms cite for your target queries and adjusting strategy accordingly.

How long does GEO take to show results?

GEO typically shows initial improvements in AI citations within 4 to 8 weeks, with significant and consistent results in 3 to 6 months. Schema markup and structured data changes can produce faster results as AI models reindex your content. The speed of results depends on your existing domain authority, the competitiveness of your industry, and how comprehensively GEO is implemented across your site.

Do I need GEO if I already have SEO?

Yes. Traditional SEO alone is no longer sufficient. AI search queries grew 527% year-over-year, ChatGPT processes over 2 billion queries daily, and Google AI Overviews appear in over 20% of searches. When generative AI provides a direct answer, users often do not click through to traditional search results. Without GEO, your brand is invisible to the fastest-growing segment of search. GEO builds on your existing SEO foundation by adding the optimisations that generative AI models specifically look for when selecting sources to cite.

What is the difference between GEO and traditional SEO?

Traditional SEO optimises for Google's ranking algorithm to appear in a list of search results. GEO optimises for how large language models select and cite sources when generating answers. Key differences include: SEO focuses on keywords and backlinks, while GEO focuses on entity authority, structured data, and source credibility. SEO success is measured by rankings and clicks, while GEO success is measured by AI citations and brand mentions in generated responses. SEO targets one search engine at a time, while GEO targets multiple AI platforms simultaneously.

No. 02d / Generative Engine Optimisation

ChatGPT / Perplexity / Gemini / Claude

Four engines. Four playbooks. One integrated strategy.

Generative Engine Optimisation is the work that gets you recommended by ChatGPT, Perplexity, Google Gemini, and Claude when a customer asks. Each engine reads the web differently. Each engine responds to different signals. One strategy has to cover them all.

The engines, up close

A brief field guide to the four that matter.

ChatGPT

The giant. Roughly 400 million weekly users and rising.

How we move it

ChatGPT reads the web through Bing and through its own crawler. It leans on authoritative sources, long-form content, and clear entity signals. We optimise for both, then we verify citations by running your trigger queries against the live model each week.

Primary focus

Bing visibility
Entity authority
OpenAI crawler access

Perplexity

The answer engine. Growing fast with professional users.

How we move it

Perplexity shows its work with real source URLs. This is the easiest engine to measure because you can see exactly which pages are being cited and which are not. We target high-intent query shapes and build the citation-ready content that Perplexity consistently picks up.

Primary focus

Source citation tracking
Question-led content
Fast-updating authority

Google Gemini

The embedded one. Every Android phone, every Google Workspace.

How we move it

Gemini is embedded across Google's surface area, including Android assistants and Workspace. It draws heavily on Google's own ranking signals, so SEO and AEO work compounds here automatically. We supplement with Gemini-specific entity reinforcement.

Primary focus

Google authority signals
Knowledge graph linking
Workspace crawler access

Claude

The thoughtful one. Favoured by developers, analysts, and enterprise.

How we move it

Claude leans on carefully-curated training data and has a strong bias for well-structured, fact-checked content. It is less volatile than the others but harder to move. We focus on long-form authority content, clean structured data, and brand consistency across trusted sources.

Primary focus

Structured data quality
Long-form authority
Brand consistency
