GEO vs AEO vs SEO: What Each One Means and How to Optimise for All Three
By the Growth Dash team · 7 min read
Short answer: SEO gets your pages ranked in search results, AEO structures content so it can be used directly as an answer, and GEO improves how generative AI tools such as ChatGPT, Gemini and Perplexity understand, cite and recommend your brand. They share the same foundations, so you do not need three separate strategies. You need one strong strategy with a few additions.
What is SEO?
Search engine optimisation is the work of helping search engines find, understand and rank your pages. It covers technical health (crawlability, speed, mobile usability), content that matches what people search for, and authority signals such as links and mentions from other websites. The goal is to appear in the traditional results and drive clicks.
What is AEO?
Answer engine optimisation focuses on being the direct answer. That includes featured snippets, People Also Ask boxes, voice assistants and the summaries search engines now show above results. AEO content is built around a clear question, followed by a concise, accurate answer and supporting detail.
What is GEO?
Generative engine optimisation is about visibility inside AI-generated responses. When someone asks an AI assistant to recommend a provider or explain a topic, the system draws on a mix of its training data and, in many products, live web results. GEO work aims to make your brand and your content easy for those systems to understand and trustworthy enough to mention.
How they compare
- Goal: SEO earns a ranked link. AEO earns the direct answer. GEO earns a mention or citation in an AI response.
- Content format: SEO rewards depth and relevance. AEO rewards clear, concise answers. GEO rewards clarity, evidence and consistent brand information.
- Key signals: SEO relies on relevance, authority and page experience. AEO adds structure and schema. GEO adds entity clarity and independent third-party mentions.
- Measurement: SEO uses rankings, clicks and conversions. AEO uses snippet and PAA presence. GEO uses prompt testing, AI referral traffic and branded search growth.
The honest caveat about AI search
No agency, including ours, controls what an AI system says. Answers vary between users, locations, models and days, and the platforms change how they work often. Be cautious of anyone who guarantees citations in ChatGPT or Google AI Overviews. What you can do is improve the factors that make being mentioned more likely and measure the results honestly.
A practical checklist for all three
1. Make sure the basics work
Pages must be crawlable, indexable, fast on mobile and free from technical errors. If a search engine cannot reliably read your site, AI systems that use its index will struggle too. A technical SEO audit is the best place to start.
2. Answer real questions directly
List the questions your customers ask before buying. Answer each in a clear heading followed by a short, direct paragraph, then expand with detail, examples and comparisons. This helps both snippet eligibility and AI summarisation.
3. Be explicit about who you are
Have a clear About page, named authors with relevant experience, accurate contact details and consistent business information across your site and profiles. Use Organization, Person and LocalBusiness schema where it applies. This is the foundation of entity clarity.
4. Add structured data
Schema markup such as FAQ, Article, Product and BreadcrumbList helps machines interpret page content. It does not guarantee features, but it reduces ambiguity.
5. Earn independent mentions
AI systems and search engines both weigh what other credible sources say about you. Reviews, industry directories, press coverage, partnerships and genuinely useful resources all help. This is where digital PR and link building support AI visibility.
6. Publish original value
Original data, first-hand experience, clear comparisons and expert commentary are harder to replace with a generic summary. Content that adds something new is more likely to be cited.
7. Consider an llms.txt file
An llms.txt file is a simple, emerging convention that points AI crawlers to your most useful pages. It is optional and not a ranking factor, but it is easy to add and can help clarify what matters on your site.
8. Track visibility, not only rankings
Test a fixed list of buyer-style questions in major AI tools every month, record whether your brand appears and how it is described, and watch referral traffic from AI platforms and branded search trends.
Should you invest in GEO now?
If your buyers research with AI assistants, yes, but build on SEO instead of replacing it. Most of the work, such as a fast site, helpful content, clear authorship and a good reputation, benefits every channel at once.

Frequently Asked Questions
They overlap heavily. SEO focuses on ranking pages in search results, while GEO focuses on how generative AI tools understand and mention your brand. The same foundations support both.
No. AI outputs vary and are controlled by the platform. You can improve the signals that make a mention more likely, such as clear content, credible third-party mentions and structured data.
