SEO vs GEO vs AEO: What’s the Difference?
The world of digital visibility is changing fundamentally. Alongside traditional SEO, two new disciplines have emerged: GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization). In this comprehensive comparison, you will discover what each strategy entails, when to deploy which one and how they work together for maximum online visibility.

Each Strategy in Detail
SEO — Search Engine Optimization
SEO is the established discipline focused on improving your position in traditional search results. It encompasses technical optimisation (speed, mobile, crawlability), on-page elements (titles, meta descriptions, heading structure) and off-page authority (backlinks, brand signals).
While some claim SEO is dying, it remains the foundation for all digital visibility. AI models are trained on web content indexed by search engines. A strong SEO foundation is therefore a prerequisite for success in GEO and AEO.
Greatest strength: Proven track record, measurable, scalable and still responsible for the largest share of organic traffic.
GEO — Generative Engine Optimization
GEO is the newest discipline, focused on visibility in AI-powered search results. Think Google’s AI Overviews, Perplexity, Microsoft Copilot and other generative search engines that synthesise answers from multiple sources.
The difference from SEO: with GEO, it is not about a ranking position but about being cited as a trusted source in the AI-generated answer. This requires high E-E-A-T content, factual accuracy, structured data and a strong citation pattern across the web.
Greatest strength: First-mover advantage is enormous. Most competitors are not yet investing here, while AI search engine usage is growing explosively.
AEO — Answer Engine Optimization
AEO goes a step further than GEO. Where GEO focuses on AI search engines, AEO focuses on AI assistants that provide direct answers and recommendations — ChatGPT, Claude, Gemini, Siri and similar platforms.
With AEO, everything revolves around brand authority: how well does the AI know your brand? Are you recommended when users ask for solutions in your category? This requires a consistent digital footprint, strong brand signals, positive reviews and authority content absorbed by AI models into their knowledge.
Greatest strength: Direct conversion impact. When an AI assistant recommends your brand, user intent is at its peak and conversion rates are significantly higher than traditional search results.
When to Choose Which Strategy?
Prioritise SEO when:
- You lack a strong organic foundation
- Your audience primarily searches via Google
- You need local or e-commerce visibility
- You want a measurable, proven strategy
Prioritise GEO when:
- Your audience increasingly uses AI search engines
- You operate in a B2B or SaaS market
- You want to build thought leadership
- Your competitors are not yet investing here
Prioritise AEO when:
- Brand positioning is your primary goal
- You are in a category where AI recommendations are valuable
- You want direct conversions from AI platforms
- You are willing to invest in authority building
Ideal: combine all three
The most powerful strategy combines SEO as the foundation, GEO for AI search visibility and AEO for brand authority. This integrated approach ensures your brand is visible at every digital touchpoint — now and in the future.
How W69 Integrates SEO, GEO and AEO
At W69, we do not believe in choosing a single channel. Our AI Visibility service combines SEO, GEO and AEO into one integrated system. We start with an AI Visibility Audit that maps your current visibility across all three channels.
We then build a Content & Authority System that produces content simultaneously optimised for search engines, AI search platforms and AI assistants. This includes structured data, E-E-A-T signals, citation patterns and brand authority building.
The result: your brand appears consistently, regardless of how your audience searches. That is what we call AI Visibility — and it is the future of digital visibility.
