Just getting familiar? Check out our simple explanation here. Keep reading for the more in-depth explanation.
So, you want to learn more about generative engine optimization (GEO), and you already get the gist. You’ve come to the right place, this is a thorough explanation of what GEO is, how it functions and what you can do to optimize for GEO.
What is GEO, really?
Generative Engine Optimization is the strategic process of optimizing content to be easily understood, extracted, and synthesized by AI-driven search engines and large language models (LLMs) such as Google's AI Overviews, ChatGPT, Gemini, Claude and more.
Unlike the traditional SEO we’re all used to designing web strategy around today, which primarily aims to rank web pages higher in a list of search results, GEO focuses on ensuring content is directly used as a source for AI-generated answers for users.
How does GEO work?
The core difference between SEO and GEO lies in the end-result AI output for users:
- SEO optimizes for a list of links on a Search Engine Results Page (SERP) and the goal is to drive clicks to your website, involving meticulous keyword research, backlink building, technical optimization and crafting content that appeals to search engine algorithms to achieve a high ranking.
- GEO is different in that it optimizes for direct answers and synthesized responses because AI-powered engines don't just present links to user but instead generate conversational answers that pull information from various sources.
Key Findings: Top-Performing GEO Optimizations
Based on a peer-reviewed study conducted by researchers from Princeton, Georgia Tech, Allen Institute for AI, and IIT Delhi, published in November 2023, the following optimizations were identified as most impactful:
- Quotation Additions
- Statistics Additions
- Fluency Optimization
- Cited Sources
- Technical Terms
- Authoritative Communication

Examples: Real Optimization in Action
Visualizations in the original study show source content with additions in green and deletions in red. These examples demonstrate that even minimal edits—adding citations, statistics, or quotes—can boost content performance without needing to rewrite entire sections.
What you can do to optimize your sites for GEO: Top 3 Data-Driven Strategies
1. Prioritize High-Quality Authoritative and Comprehensively Structured Content
Your goal with GEO is to be the authoritative source that an AI chooses to reference and cite or even directly quote from in its output to users. This means shifting your focus from merely ranking to instead making sure that your content is clear, factual, well-structured and easy for an AI to simply interpret and integrate into its generated responses.
A good rule of thumb is to demonstrate expertise, experience, authoritativeness, and trustworthiness, or E-E-A-T, for short.
2. Focus on Conversational Language and Natural Language Queries:
Generative AI excels at understanding natural, conversational language so instead of optimizing for fragmented keywords think about how a user might phrase a question to a chatbot or voice assistant. Incorporate long-tail, conversational keywords and phrases that reflect user intent, crafting content that directly addresses common questions and provides clear, unambiguous answers.
Break down information with headings and lists, make sure to use clear and concise language and consider employing structured data (Schema markup) to label different content elements, to make it easier for AI to synthesize your information.
3. Leverage Data, Statistics, and Expert Citations:
AI models value factual accuracy and credible sources so ensure that you back up any and all claims with data, statistics, and references to reputable studies or expert opinions since including relevant quotes from industry experts or citing well-known figures can further enhance the trustworthiness and authority of your content in the eyes of the Generative AI, making it more appealing to draw upon.
5 helpful ways to improve copywriting for GEO:
1. Add Quotations from Experts: Improves performance by up to 40%
Adding direct quotes from credible individuals or organizations boosts trust and relevance, especially in topics related to society, history, or explanation-based queries. Think of it as giving the AI a reason to “pull” your text as a source.
Example: “AI is a force multiplier for good,” Dr. Maria Chen, director of AI4Good.
2. Include Relevant Statistics: Boosts visibility by up to 40%
Numbers add weight. Including data points makes your content more factually grounded, which helps AI include it in responses to factual or persuasive questions especially in domains like law, government, or opinion-based topics.
Example: According to the WHO over 70% of the global population will live in urban areas by 2050.
3. Optimize for Fluency and Readability: Improves impression metrics up to 30%
Generative engines prefer clean, well-written content. Sentences should be clear, grammatical, and logically ordered. This isn't just about grammar but about how effortlessly the model can process and reproduce your content.
4. Cite Reliable Sources: Enhances credibility and ranking
GEO is grounded in verifiable content. Linking or referencing known sources—even within your body text—signals trustworthiness. This is particularly effective for factual, health, science, and finance-related content.
Example: A recent report from McKinsey found that generative AI could add up to $4.4 trillion annually to the global economy.
5. Use Domain-Relevant Technical Terms: Boosts ranking in industry-specific queries
Inserting accurate, domain-specific terminology improves discoverability for expert-level and niche queries. It helps generative models associate your content with deeper expertise in a given topic.
15 Practical Improvements for GEO on Websites
1. Add Structured Data (Schema.org Markup)
Why it matters: Generative engines use structured data to understand context. This helps them extract the right facts (like your name, business, reviews, or article content) more accurately.
How to do it:
- Use schema.org tags for:
- Article for blogs
- Person or Organization for author/company pages
- FAQPage and HowTo for tutorials Product for e-commerce
- Use JSON-LD format preferred by Google & AI scrapers
- Validate with Google’s Rich Results Test
2. Add Source-Ready Quotations and Stats in HTML
Why it matters: GEs often quote websites verbatim so adding relevant and direct quotes and up-to-date statistics improves the chance of being pulled into a response.
How to do it:
- Include quotable pull quotes in <blockquote> or <q> tags.
e.g.: <blockquote>“AI will reshape every industry within 5 years.” – CEO, Acme AI</blockquote>
- Add current data with <strong> or <em> tags to make them stand out.
3. Improve Meta Descriptions and Titles with GEO Prompts
Why it matters: GEs sometimes surface metadata or page summaries and so meta descriptions help models understand your page’s intent and content.
How to do it:
- Use tools like ChatGPT to help you write meta titles/descriptions using prompts like: “Write a meta description for a blog about how nonprofits can use AI to reduce costs.”
- Ensure every page has a unique, 150–160 character meta description that summarizes your key value.
