AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization) are two terms for the same discipline: optimizing your brand's visibility in AI-powered search engines like ChatGPT, Perplexity, Gemini, and Google AI Overviews. The terms emerged independently — AEO from the search marketing community, GEO from academic research — but they describe identical strategies and outcomes.
What Is AEO (Answer Engine Optimization)?
AEO, or Answer Engine Optimization, is the practice of optimizing your website and content to be recommended and cited by AI search platforms. Unlike traditional SEO which focuses on ranking in Google's link-based results, AEO targets AI systems that synthesize answers from multiple sources and recommend specific brands, products, or services.
The term 'Answer Engine' reflects how these platforms work: users ask questions, and AI engines provide direct answers — often citing and recommending specific solutions. When someone asks ChatGPT 'what's the best CRM for small businesses?', the AI doesn't show a list of links. It recommends specific products. AEO determines whether your brand is one of them.
What Is GEO (Generative Engine Optimization)?
GEO, or Generative Engine Optimization, refers to the same practice but emphasizes the 'generative' nature of AI search. The term was popularized by a 2024 research paper from Georgia Tech, IIT Delhi, and other institutions that studied how to optimize content for AI-generated responses.
GEO highlights that these search engines generate responses rather than simply listing links — a fundamental shift in how search works. The research identified key factors including citation frequency, authoritative sources, structured data, and factual density as primary drivers of AI visibility.
AEO vs GEO: Are They Actually Different?
No. AEO and GEO describe the same strategies, target the same platforms, and use the same optimization techniques. The difference is purely terminological. AEO is more common in the marketing industry and practitioner community. GEO appears more frequently in academic papers and research contexts.
At Aeranko, we use the term AEO because it clearly describes the outcome: getting your brand into AI-generated answers. But our platform covers everything in the GEO methodology as well — they're interchangeable.
- AEO stands for Answer Engine Optimization — coined by the search marketing community
- GEO stands for Generative Engine Optimization — coined by academic researchers
- Both target the same platforms: ChatGPT, Perplexity, Gemini, Google AI Overviews, Claude
- Both use the same optimization strategies: authority, structured content, schema markup
- The only difference is terminology — use whichever your audience recognizes
How AEO/GEO Differs from SEO
While AEO/GEO and SEO share some foundations, they target fundamentally different systems. SEO optimizes for Google's ranking algorithm — links, keywords, page speed, and domain authority determine your position in a list of blue links. AEO/GEO optimizes for AI recommendation systems — authority, factual density, content structure, citerability, freshness, and schema markup determine whether AI platforms mention and recommend your brand.
The key distinction: SEO is about ranking in a list. AEO is about being recommended in a conversation. With 60% of Google searches now resulting in zero clicks, and AI search queries growing 527% year-over-year, the brands that invest in both SEO and AEO will dominate discovery for the next decade.
- SEO signals: backlinks, keywords, Core Web Vitals, page speed
- AEO signals: citations, structured data, factual density, citerability
- SEO results: 10 blue links on a search page
- AEO results: a synthesized answer that may cite 0-5 sources
- You need both — SEO gets you found on Google, AEO gets you recommended by AI
The 6 Factors of AEO/GEO Visibility
Aeranko measures AI search visibility using 6 weighted factors that determine whether AI platforms cite your brand. Authority (25%) measures your citations in sources that AI platforms trust. Factual Density (20%) scores your content for specific, verifiable claims versus vague statements. Structure (20%) evaluates your FAQ sections, heading hierarchy, and comparison tables.
Citerability (15%) measures whether AI can extract complete, standalone sentences from your content. Freshness (10%) tracks your update frequency and visible dates. Schema (10%) evaluates your JSON-LD structured data, Open Graph tags, and llms.txt file. Together, these six factors produce your AEO Score — a 0-100 rating of your AI search readiness.
