AEO vs. SEO vs. GEO: what is the difference?
SEO, AEO and GEO describe overlapping ways to improve how people and digital systems find and use your information. The labels differ; many of the most valuable website improvements are shared.
| Discipline | Main focus | Typical work | What to measure |
|---|---|---|---|
| SEO | Visibility in traditional search results | Technical access, intent-matched content, internal links, reputation and page experience | Search impressions, clicks, query positions, conversions and index coverage |
| AEO | Clear, useful answers to specific questions | Direct explanations, well-structured sections, evidence, authorship and extractable context | Relevant search visibility, referral traffic and sampled answer citations |
| GEO | Visibility in generative search and AI-generated responses | Strong source material, entity clarity, reputable references and content that answers multi-part intent | Brand mentions, cited URLs and presence across a defined prompt set |
SEO: help people discover the right page
SEO is the broad foundation. A search engine needs to discover a URL, crawl it, understand the page and decide whether it is useful for a query. That work includes technical health, content quality, information architecture, links and reputation. An AEO or GEO campaign that ignores SEO fundamentals is likely to inherit the same discovery and quality problems.
AEO: make the answer understandable
AEO puts extra attention on the information a reader needs to resolve a question. A strong page defines its subject, answers the question directly, provides conditions and context, and supports claims with evidence. Clear section headings and well-labelled lists or tables help human readers and can make passages easier to interpret.
GEO: earn visibility in generative experiences
GEO is commonly used for work intended to improve a brand or page's presence in generative search experiences. It includes the same on-site clarity and technical foundations as SEO and AEO, but it also depends on the wider information environment: whether other credible sources refer to the brand, whether facts are consistent, and whether the content is relevant to questions the model or search system is answering.
What should a small website do first?
- Fix access before polish. Make sure important public pages return successfully, are not unintentionally blocked and have sensible canonical and indexing directives.
- Improve the page that serves the intent. Give every important topic one clear, useful destination rather than creating many thin variations.
- Show evidence. Add original examples, product details, author context, accurate dates and links to primary sources where they help verify a claim.
- Make entities consistent. Keep business names, product facts, author information and contact details consistent wherever they appear.
- Measure separately. Search Console reports search performance; manual or dedicated AI prompt testing measures sampled mentions and citations. Neither metric replaces the other.
Do you need separate pages for SEO, AEO and GEO?
Only when the audience and intent are genuinely different. Do not publish three pages that repeat the same copy with different acronyms. A single comprehensive page can explain the shared process, while focused pages can answer distinct questions such as how to validate crawler access or how to measure AI mentions.
Google's published guidance says the usual Search fundamentals apply to its AI features and that there are no extra technical requirements or special schema just for AI Overviews or AI Mode. Read Google's generative AI search guidance before spending time on supposed AEO hacks.
