From SEO to GEO: The Complete Guide to AI Search Optimization
This article was written by Pallas AI Agent and may contain minor errors.
The rules of search visibility have fundamentally changed. Your content might rank first on Google, yet remain invisible when users ask ChatGPT, Perplexity, or Claude the same question. Generative Engine Optimization (GEO), also known as Answer Engine Optimization (AEO), represents the new frontier of digital discoverability. Brands that master both traditional SEO and emerging GEO strategies gain a significant competitive advantage, appearing not just in search results but directly in AI-generated answers. Platforms like Pallas AI now help brands monitor and optimize their presence across these AI search engines, tracking citations, analyzing visibility gaps, and generating content that AI systems trust and recommend.
This comprehensive guide explores the relationship between SEO and GEO/AEO, examines the technical foundations driving AI search, reviews the latest academic research, surveys the growing ecosystem of optimization tools, and provides actionable strategies for brands navigating this new landscape.
Understanding GEO, AEO, and LLMO: More Than Just New Names
GEO, AEO, and LLMO all describe the same fundamental shift: optimizing content to be cited in AI-generated responses rather than just ranked in traditional search results. The terminology varies by context, but the underlying goal remains consistent.
The Evolution of Search Optimization Terminology
SEO (Search Engine Optimization) emerged in the 1990s as webmasters learned to optimize content for Google and other traditional search engines. The goal was simple: rank higher in the list of ten blue links. Success meant driving clicks to your website.
AEO (Answer Engine Optimization) gained traction around 2016-2018 as featured snippets and voice search became prominent. The focus shifted toward being selected as THE answer, not just appearing in results. Google's answer boxes and voice assistant responses required a new optimization mindset.
GEO (Generative Engine Optimization) was formally introduced by researchers at Princeton University in their landmark 2023 paper. This term specifically addresses optimization for AI systems that generate comprehensive responses by synthesizing multiple sources. The academic community has largely adopted this terminology.
LLMO (LLM Optimization) appears in some practitioner circles, emphasizing the large language model aspect of these AI systems. While less common than GEO or AEO, it accurately describes the technical target of optimization efforts.
The Fundamental Shift in Optimization Goals
Traditional SEO optimizes for ranking position within an index. The metrics are clear: position 1 beats position 2, which beats position 3. Click-through rates correlate predictably with rank.
GEO/AEO optimizes for citation probability within AI-generated answers. The dynamics differ significantly:
- Multiple sources matter: AI responses often cite 3-10 sources, not just one winner
- Context determines selection: The same content may be cited for some queries but not others
- Synthesis quality counts: How well your content integrates into the AI's answer affects user perception
- Authority signals differ: AI systems evaluate trustworthiness through different mechanisms than traditional search
The shift can be summarized as moving from "getting users to click on me" to "getting AI to cite me."
Why SEO Still Matters for GEO Success
GEO does not replace SEO; it builds upon it. Most AI search engines rely on traditional search indexes for content retrieval. ChatGPT's web browsing mode uses Bing. Perplexity queries multiple search engines. Google's AI Overviews draw from the same index as traditional search.
This creates a two-stage optimization challenge:
- Stage 1 (Retrieval): Your content must be indexed and rank reasonably well in traditional search to be retrieved by AI systems
- Stage 2 (Citation): Among retrieved content, your material must be selected for inclusion in the AI-generated response
Neglecting SEO fundamentals means your content never reaches Stage 2. Mastering only SEO without GEO considerations means your content gets retrieved but not cited.
The Rise of AI Search: Why Now?
Over one billion people now use AI tools regularly, with ChatGPT alone reaching 800 million weekly active users and 5.6 billion monthly visits [1][2]. This explosive adoption has fundamentally altered how people discover information and make decisions.
Explosive Growth in AI Search Usage
The numbers tell a compelling story:
ChatGPT has become the fourth most-visited website globally. Sam Altman announced in October 2025 that ChatGPT serves more than 800 million weekly active users [1]. Weekly active users grew 700% year-over-year from November 2023 [3]. Users send over 2.5 billion prompts daily [4].
Perplexity processed 780 million search queries in May 2025, representing 20%+ month-over-month growth [5]. The platform has attracted 15-30 million monthly active users [6].
Google AI Overviews expanded to 200+ countries and 40+ languages by May 2025 [7]. At peak coverage in July 2025, AI Overviews appeared in approximately 25% of queries, though this later stabilized around 16% [8].
DataReportal confirms that over one billion people worldwide now use AI tools regularly, marking a fundamental shift in information-seeking behavior [2].
How AI Search Differs from Traditional Search
Traditional search engines present users with a list of links. Users must click through, evaluate multiple sources, and synthesize information themselves. The search engine's role is curation and ranking.
AI search engines provide direct answers. They retrieve relevant sources, synthesize information, and present a coherent response. Users often get their answer without clicking any links. The AI's role is not just curation but also synthesis and explanation.
This creates three key differences:
| Aspect | Traditional Search | AI Search |
|---|---|---|
| Output | Ranked list of links | Synthesized answer with citations |
| User action | Click and evaluate multiple sources | Read answer, optionally verify sources |
| Content consumption | Full page visits | Extracted snippets and facts |
| Success metric | Clicks and rankings | Citations and visibility in answers |
| Optimization target | Single query ranking | Multi-query topic coverage |
The Commercial Implications
Zero-click searches have increased dramatically with AI search. Users get answers without visiting websites. For brands, visibility in the AI response itself becomes the new top-of-funnel metric.
Brand mentions in AI answers function as implicit endorsements. When ChatGPT recommends a product or cites a company as an authority, users perceive this as AI validation.
The value chain is shifting. Traditional SEO drove traffic that brands could monetize through ads, conversions, or engagement. GEO drives brand visibility and credibility even when users never visit your site.
The Technical Foundations of GEO
AI search engines use a two-phase process: first retrieving potentially relevant content from web indexes, then using large language models to synthesize responses from retrieved material. Understanding both phases is essential for effective optimization.
Content Retrieval: How AI Systems Find Your Content
Reciprocal Rank Fusion (RRF)
When AI systems search for information, they often issue multiple sub-queries and combine results using Reciprocal Rank Fusion [18]. The formula: S(d) = Sum of 1/(k + rank) across all queries where the document appears, with k typically around 60.
The practical implications are significant:
- Multi-query presence matters more than single-query dominance: Appearing in the top 40 for two related queries beats ranking #1 for just one
- Topic cluster coverage is essential: Your content should address multiple angles of a topic
- The magic threshold appears around 0.020: Reaching this RRF score typically ensures inclusion in the citation pool
Testing with ChatGPT reveals it retrieves 38-65 results depending on query type [18]. Technical queries tend to retrieve more sources; simple factual queries retrieve fewer.
Query Fan-Out
AI search systems employ query fan-out, decomposing complex user questions into 5-15 sub-queries [19]. Each sub-query searches independently, and results are merged.
For a question like "What's the best project management tool for a remote team of 20 people?", the AI might generate sub-queries for:
- Best project management tools 2025
- Project management software for remote teams
- Team collaboration tools for 20 people
- Project management pricing comparison
- Remote work software features
Content that appears across multiple sub-queries gains higher visibility in the final response. This underscores the importance of topic cluster strategies covering various angles and related questions.
Content Synthesis: How AI Systems Select Citations
Authority Signals
AI systems evaluate authority through signals including:
- Domain reputation: Wikipedia, established publications, and official brand sites carry weight
- Content structure: Well-organized content with clear headings, lists, and tables is easier to extract
- Citation presence: Content that cites credible sources tends to be cited more often
- Freshness: For time-sensitive topics, recent content receives preference
Content Quality Signals
Research from the Princeton GEO paper identified several content characteristics that improve AI visibility:
- Adding citations to support claims boosted visibility by 40%+
- Including statistics and specific data points improved citation rates
- Structured formatting with bullet points, numbered lists, and tables enhanced extractability
- Fluency optimization alone showed limited impact
LLM Biases in Citation Selection
Academic research has uncovered several biases affecting which content gets cited:
Self-preference bias: LLMs tend to favor content with lower perplexity (more predictable text patterns). This inadvertently favors content that "sounds like" AI-generated text.
Political bias in citations: Research published at EMNLP 2025 found LLMs cite certain political perspectives more frequently than others.
AI-AI bias: A Nature sub-journal study demonstrated that LLMs show preference for content generated by other AI systems.
These biases present both challenges and opportunities. Content optimized for AI readability may gain citation advantages, but authenticity and unique perspectives remain valuable differentiators.
Academic Research: The Science of GEO
The academic study of GEO began with the Princeton paper in November 2023 and has since expanded to cover benchmarking, bias analysis, and adversarial attacks. This research provides the theoretical foundation for practical optimization strategies.
The Foundational Princeton Paper
"GEO: Generative Engine Optimization" was published by Pranjal Aggarwal, Vishvak Murahari, and colleagues from Princeton University and IIT Delhi [9]. Accepted at KDD 2024, this paper introduced:
- The GEO framework: A formal definition of optimization for generative engines
- GEO-BENCH: A benchmark dataset with diverse queries and relevant sources
- Nine optimization strategies: Tested interventions including citation addition, statistics inclusion, and readability improvements
- Quantified results: Citation addition improved visibility by up to 40% in generative engine responses [9]
The paper established that traditional SEO techniques are insufficient for AI search and that specific content modifications can significantly impact AI citation probability.
Subsequent Research Developments
Methodology and Benchmarking
AutoGEO (arXiv, October 2025) introduced automated preference learning for generative engines [10]. The framework extracts content preference rules and rewrites content to maximize visibility while preserving accuracy.
"Generative Engine Optimization: How to Dominate AI Search" (arXiv, September 2025) provided large-scale comparative analysis between AI search and traditional web search, revealing systematic biases toward earned media over brand-owned content [11].
E-GEO (arXiv, 2025) created a testbed specifically for e-commerce GEO, recognizing the unique optimization challenges in product discovery [12].
Bias and Preference Research
Academic work has documented multiple biases in LLM citation behavior:
- LLMs favor content with specific linguistic patterns
- Citation selection varies across domains
- User personalization affects which sources appear
- Model versions show different preference profiles
Adversarial Research
StealthRank and related papers demonstrate that LLM ranking systems can be manipulated through carefully crafted content modifications. While these techniques raise ethical concerns, understanding them helps legitimate optimizers avoid inadvertently triggering spam detection.
Open Research Questions
The field continues to grapple with:
- Standardized evaluation: No consensus exists on how to measure GEO success
- Cross-model consistency: Strategies effective for ChatGPT may not work for Claude or Gemini
- Longitudinal effects: How optimization strategies perform over time as models update
- Ethical boundaries: Where legitimate optimization ends and manipulation begins

AI platforms are rapidly evolving from information tools to commerce platforms, with ChatGPT introducing shopping features and Chinese platforms achieving full e-commerce integration. These developments make GEO increasingly tied to revenue impact.
ChatGPT's Commerce Evolution
Shopping Research launched in November 2025, enabling ChatGPT to help users find products with built-in price comparison and reviews [13]. Millions of users now ask ChatGPT what to buy.
Instant Checkout arrived in September 2025, allowing purchases directly within ChatGPT conversations [14]. Initial merchant partners include Etsy and Shopify stores, with payment processing through Stripe and PayPal [15].
ChatGPT Ads are expected in 2026 as part of OpenAI's broader monetization strategy [16]. This will create direct advertising opportunities within AI conversations.
For brands, these developments mean AI visibility directly impacts commerce. Being recommended by ChatGPT when users ask "what should I buy?" drives sales.
Google's AI Commerce Response
AI Overviews continue evolving, now reaching 1.5 billion monthly users across 200+ countries. Google is integrating its Shopping Graph with AI features, creating AI-powered product discovery.
The impact on traditional traffic is significant. Some analyses suggest AI Overviews may reduce referral traffic by up to 25% as users find answers without clicking through.
China's AI Commerce Integration
China's market demonstrates the most advanced AI-commerce integration:
Qwen (Alibaba's AI) announced full integration with the Alibaba ecosystem in January 2026 [17]. Users can order food, purchase products, book travel, and make payments entirely within AI conversations. Over 400 AI-powered services launched simultaneously.
Doubao (ByteDance's AI) began directing users to Douyin e-commerce during Singles' Day 2025. With 155 million monthly active users, Doubao represents a massive commerce opportunity [17].
These platforms show where global AI commerce is heading: seamless integration between AI assistants and transaction capabilities. Brands invisible to these AI systems miss significant revenue opportunities.

| Search + AI fusion | Advertising | AI Overviews + Shopping | |
| Alibaba/Qwen | Ecosystem integration | E-commerce transactions | Full transaction closure |
| ByteDance/Doubao | Content + Commerce | E-commerce referrals | Douyin marketplace integration |
| Perplexity | Independent search | Subscription + Ads | Limited (referral links) |
Challenges and Unsolved Problems
Despite rapid progress, GEO faces significant challenges including attribution difficulties, lack of official data, and personalization effects that make optimization inherently uncertain. Practitioners must navigate these limitations strategically.
The Attribution Problem
Traditional digital marketing relies on tracking user journeys from impression to conversion. AI search breaks this model:
- Zero-click discovery: Users learn about brands in AI responses without visiting websites
- Multi-step influence: A user might see your brand in ChatGPT, later search for it on Google, and finally convert through an ad
- Invisible recommendations: AI mentions occur in private conversations with no visibility to the brand
Current solutions remain imperfect:
- GA4 filters can identify some AI-referral traffic
- Brand search volume correlation provides indirect signals
- Survey-based attribution helps understand influence paths
The fundamental question persists: How do you value and measure visibility that occurs within AI conversations you cannot observe?
Lack of Official Performance Data
SEO professionals rely on Google Search Console for clicks, impressions, and ranking data. No equivalent exists for AI search.
Why official data may never come:
- Privacy concerns around conversation monitoring
- Competitive dynamics preventing platform transparency
- Technical complexity of measuring conversational interactions
Workarounds include:
- Third-party estimation tools (limited accuracy)
- Brand search volume as a proxy metric
- Direct traffic analysis for correlation patterns
- Manual testing and monitoring
Personalization Uncertainty
AI responses vary based on:
- User conversation history
- Geographic location
- Subscription tier (free vs. paid)
- Model version and settings
This creates fundamental uncertainty. The same content might be cited for one user and ignored for another. A/B testing becomes complex when the "A" and "B" conditions cannot be controlled.
Additional Challenges
Rapid model evolution: Optimization strategies may become obsolete with model updates. What works today might fail tomorrow.
Black-box systems: We cannot fully understand why specific content gets cited. Optimization involves educated guessing and testing.
Multi-platform fragmentation: ChatGPT, Claude, Gemini, and Perplexity have different preferences. Optimizing for all simultaneously is resource-intensive.
ROI measurement: Without clear attribution, justifying GEO investment to stakeholders is difficult. The value proposition relies partly on faith in future importance.
Practical Strategies for GEO Success
Effective GEO combines traditional SEO fundamentals with AI-specific optimizations including structured content, comprehensive topic coverage, and authority building through citations and data. Here are actionable strategies for different stakeholders.
For Content Creators
Start with SEO fundamentals. Content must be indexed and rank reasonably well to be retrieved by AI systems. Neglecting technical SEO means your content never enters consideration.
Structure content for extraction. Use clear headings, bullet points, numbered lists, and tables. AI systems extract information more easily from well-organized content.
Build topic clusters. Cover your subject from multiple angles. Create content addressing various phrasings and aspects of key questions. This improves multi-query visibility through RRF.
Add citations and data. Reference credible sources. Include specific statistics and numbers. The Princeton research showed citation addition improving visibility by 40%+.
Maintain freshness. Update content regularly, especially for time-sensitive topics. Include dates and indicate when content was last reviewed.
Answer questions directly. Start paragraphs with clear statements. AI systems favor content that provides immediate answers rather than building to conclusions.
For Brands
Monitor AI visibility. Use tools like Pallas AI to track how often and where your brand appears in AI responses. Identify gaps and opportunities.
Optimize owned content for citation. Your website, blog, and official communications should be structured for AI extraction. This includes FAQs, comparison tables, and clear factual statements.
Build presence on cited sources. AI systems often cite Wikipedia, review sites, and industry publications. Ensure accurate representation across these platforms.
Engage with the AI commerce ecosystem. If relevant, participate in ChatGPT shopping, AI-integrated marketplaces, and emerging commerce platforms.
Invest in earned media. Third-party coverage from trusted publications carries weight with AI systems. PR and analyst relations contribute to AI visibility.
For Marketing Teams
Learn GEO fundamentals. Understand how AI search works technically. The investment in knowledge pays dividends across all optimization efforts.
Establish tracking systems. Even imperfect measurement beats flying blind. Set up GA4 filters, monitor brand search volume, and track tool-based visibility estimates.
Adjust KPIs. Citation counts, share of voice in AI responses, and brand mention sentiment are emerging metrics. Traditional click-based metrics capture only part of the picture.
Test across platforms. ChatGPT, Claude, Perplexity, and others have different behaviors. Develop platform-specific insights through systematic testing.
Stay current with research. The field evolves rapidly. Academic papers, industry reports, and platform announcements provide strategic intelligence.
