Difference Between SEO and GEO
Search is changing. In 2025, nearly half of all Google queries now trigger AI-generated overviews, and platforms like ChatGPT, Perplexity, and Gemini are shaping how users discover information[1][2].
For businesses, this shift means that traditional search engine optimization (SEO) alone is no longer enough. Generative engine optimization (GEO) has emerged as a critical strategy for brands aiming to be visible in AI-generated answers and summaries. AthenaHQ, founded by experts from Google Search and DeepMind, leads this new field by providing AI-powered optimization tools designed specifically for generative AI platforms.
This article explains the core differences between SEO and GEO, why GEO matters now, and how AthenaHQ’s expertise helps businesses adapt and thrive in the era of AI-driven search.
SEO vs GEO: Core Definitions
What is SEO?
Search engine optimization (SEO) is the established practice of improving a website’s visibility in traditional search engine results pages (SERPs) like Google and Bing. SEO strategies include keyword optimization, backlink building, technical site improvements, and content creation focused on ranking higher for specific queries[3][4][5].
What is GEO?
Generative engine optimization (GEO) is a newer discipline focused on optimizing content for AI-driven search engines and answer platforms such as ChatGPT, Perplexity, and Google’s AI Overviews. GEO aims to increase the likelihood that your content is cited, referenced, or synthesized in AI-generated responses, not just listed as a clickable link[6][7][8].
Key Differences: SEO vs GEO
| Criteria | SEO (Search Engine Optimization) | GEO (Generative Engine Optimization) |
|---|---|---|
| Target Platform | Google, Bing, traditional search engines | ChatGPT, Perplexity, Gemini, AI Overviews |
| Content Structure | Keyword-focused, skimmable, link-based | Fact-rich, integrative, citation-heavy |
| Success Metrics | Click-through rate, SERP ranking, traffic | AI mentions, citations, inclusion in answers |
| User Experience | Users click links to visit sites | Users get direct answers with sources |
| Optimization Approach | Manual research, technical SEO, backlinks | AI-driven analysis, entity optimization, authoritative content |
| Performance Tracking | Keyword rankings, organic traffic | AI citation frequency, response inclusion |
Example:
An SEO-optimized article about “best project management tools” aims to rank on Google’s first page. A GEO-optimized article is structured so that ChatGPT or Gemini cites it directly in their generated summaries, increasing brand visibility even if users never click through to the original site[9][10].
How Generative AI Search Engines Work
Generative AI engines synthesize information from vast datasets to provide comprehensive, conversational answers. Unlike traditional search engines that list web pages, generative engines use large language models (LLMs) to:
Technical Insight:
Generative AI models rely on natural language processing (NLP) to interpret queries and synthesize answers. They continuously learn from new data, adapting to trends and evolving user intent.
Why GEO Matters: The New Reality of AI Search
AI-generated overviews now appear in up to 47% of Google searches, and on mobile, these overviews can cover more than 75% of the screen[13]. If your brand is not cited in the AI summary, users may never see your content—even if you rank well in traditional SERPs.
Key Implications:
- Reduced Clicks: AI answers often satisfy user intent directly, reducing the need for users to click through to websites[14].
- Citation is the Goal: GEO shifts the focus from driving clicks to securing mentions and citations in AI-generated responses[15].
- Multi-Platform Visibility: GEO targets not just Google, but a growing ecosystem of AI-driven platforms.
Pattern Interrupt: 3 Ways GEO Changes Content Strategy
- Fact-rich, authoritative content is prioritized by AI engines.
- Citations, expert quotes, and statistics increase the chance of being referenced.
- Content must be structured for both human readability and AI parsing[16].
GEO Methodologies: What Works
Recent research shows that GEO methods such as including citations, quotations from relevant sources, and statistics can boost source visibility by over 40% in generative engine responses[17]. Simple keyword stuffing is ineffective; instead, AI engines favor content that is:
- Authoritative and trustworthy
- Rich in technical terms and data
- Structured with clear citations and references
- Written fluently and optimized for clarity
GEO Optimization Checklist:
Example: A SaaS company saw a 35% increase in AI-generated mentions after restructuring their product pages to include more data-driven insights and third-party citations.
SEO and GEO: Can They Work Together?
SEO and GEO are not mutually exclusive. In fact, integrating both strategies delivers the best results:
Actionable Steps:
- Continue optimizing for traditional SEO metrics (keywords, backlinks, technical health).
- Layer in GEO tactics: enrich content with citations, statistics, and authoritative language.
- Use AI-powered tools to analyze which content is being cited by generative engines and refine accordingly.
