GEO vs SEO comes down to what you are trying to win. SEO earns a position in a list of links on Google. GEO (Generative Engine Optimization) earns a place inside an answer that an AI system writes, where there is no list and often only a few brands are named. AEO, optimizing to be the answer, is the same job seen from the assistant’s side. They share most of their foundations, and Google’s own guidance goes further: “optimizing for generative AI search is optimizing for the search experience, and thus still SEO” (Google, updated 2026-07-10).
The Princeton paper that introduced GEO reported that some content changes raised visibility in generative responses by up to 40% (arXiv). Google, for its part, advises prioritizing effective SEO strategies over AEO/GEO hacks. Both can be true: content changes help, and there is no separate trick that replaces good SEO.
GEO vs SEO at a glance
SEO is about helping search engines find and rank your web pages. When someone searches on Google, SEO determines whether your page appears in the results and how high. Success is measured in keyword rankings, organic traffic, and click-through rates from search results pages.
AEO is about helping AI systems include and accurately describe your brand in their generated answers. When someone asks ChatGPT for a product recommendation, AEO determines whether your brand is mentioned and how. Success is measured in mention rates, Visibility Scores, and sentiment in AI answers.
| SEO | GEO | AEO | |
|---|---|---|---|
| Surface | Google/Bing ranked links | Google AI Overviews, Bing Copilot | ChatGPT, Claude, Perplexity, Gemini |
| User is still searching? | Yes | Yes, but reads a summary first | No - asks the assistant directly |
| What you measure | Rank, clicks, impressions | AI Overview appearance rate | Mention rate, position, sentiment per LLM |
| Mature tooling | Ahrefs, Semrush, Google Search Console | Emerging, partly inside Search Console | Specialized tools like AskAiRank |
Is GEO different from AEO?
The terms overlap and no standard separates them. The 2023 paper uses GEO for optimizing toward any generative engine, whether it sits inside a search engine (Google AI Overviews, Bing Copilot) or is a standalone assistant (ChatGPT, Claude, Perplexity, Gemini). AEO usually names the goal of being the answer an assistant gives.
In day-to-day practice the two rarely need separate playbooks. The same clear, factual, well-structured content tends to get cited in an AI Overview and in a ChatGPT answer alike, so most indie teams track both as a single visibility number.

How they overlap
In practice, AEO and SEO share significant ground:
Content quality: high-quality, specific, factual content that answers real questions well improves both SEO rankings and AI mention rates. The same blog post that ranks for a keyword may also be retrieved by Perplexity when answering similar questions.
Authority signals: backlinks from credible sources improve your domain authority for SEO. Being cited by those same authoritative sources improves your grounding advantage in RAG-based AI systems.
Structured information: clear headings, explicit facts, comparison tables, and concise summaries help both search crawlers index your content and AI systems extract relevant information from it.
Entity recognition: SEO has evolved toward entity-based signals (is your brand a recognized entity with consistent properties?). AEO is fundamentally entity-based from the start.
Where GEO needs different work
The outcome differs. In SEO you can see your rank for a keyword. In GEO the same prompt can name different brands on different days, so the useful number is how often you are named across repeated checks, and where in the list. That is what a visibility score measures: the share of daily checks where your brand is in the top 10 of the answer. Mentions on other sites matter more here too, because the engine reads and repeats third-party sources.
The zero-click problem: good SEO typically produces a click to your website. A good AEO result means your brand is recommended by the AI, but the user may not click anywhere. AI awareness does not always translate directly to web sessions. Tracking both AI visibility and AI-sourced traffic is necessary to understand the full picture.
Measurement tools: SEO has mature tooling (Ahrefs, Semrush, Google Search Console). AEO tooling is newer and less standardized - AskAiRank is in the category of tools building this measurement layer, see AI visibility tracking.
Speed of change: Google algorithm updates are significant events that shake up rankings. AI model updates can change visibility patterns more subtly and with less warning. You also have less visibility into when these changes happen.
Multi-platform: SEO is primarily about Google (with some Bing). AEO spans ChatGPT, Claude, Perplexity, Gemini, and AI Overviews, each with different patterns.
What to do first
Fix the SEO basics (crawlable, indexed, clear pages), then add the GEO layer: facts and definitions the engine can quote, presence on the third-party pages it cites, and tracking.
- Keep doing what is working in SEO - it still drives meaningful traffic
- Add AEO monitoring as a measurement layer (AskAiRank, free tier is a reasonable start)
- When you create content, optimize for both: answer questions directly, use clear structure, cite facts and sources
- As AI-sourced traffic grows in your analytics, invest proportionally more effort in AEO
