What is GEO? Generative Engine Optimization Explained
SEO gets you on Google. GEO gets you into ChatGPT.
Generative Engine Optimization (GEO) is the practice of making your brand, product, or content appear in AI-generated answers — the outputs produced by systems like ChatGPT, Perplexity AI, and Google Gemini when users ask them questions. As those systems become a primary interface for discovery and purchase decisions, appearing in their answers has become a meaningful growth lever.
Generative Engine Optimization (GEO)
The set of strategies and practices used to increase the likelihood that an AI language model or AI answer engine will cite, mention, or recommend a specific brand, product, or piece of content when generating a response to a user query.
Why GEO matters now
Search behavior is shifting. A growing share of users — particularly for high-consideration queries — bypass Google entirely and go directly to ChatGPT or Perplexity for answers. A 2025 study by SparkToro estimated that AI answer engines now handle over 14% of informational search volume in the US, with the share growing month over month.
For B2B software companies, the impact is even more pronounced. When a buyer asks "what's the best CRM for a 10-person sales team?", they're often asking ChatGPT — not typing it into Google. If you appear in that answer, you're in the consideration set. If you don't, you don't exist for that buyer in that moment.
GEO is the discipline that closes that gap.
GEO vs SEO: what's different?
SEO
- Targets Google, Bing, and traditional search engines
- Goal: rank on page 1 for keywords
- Signals: backlinks, authority, technical structure
- Result: click-through to your website
- Measured by: organic traffic, rankings
GEO
- Targets ChatGPT, Perplexity, Gemini, and AI assistants
- Goal: get cited or recommended in AI answers
- Signals: structured content, citations, factual clarity
- Result: brand mention in the AI's response
- Measured by: citation rate, mention share
The two disciplines overlap — content that performs well in SEO often performs well in GEO, and vice versa — but they're not identical. SEO rewards authority and backlinks. GEO rewards clarity, structure, and factual credibility. A site with weak backlinks but excellent structured content can outperform a high-DA competitor in AI citations.
What GEO looks like in practice
A user types into ChatGPT: "What's the best email marketing tool for a Shopify store?"
ChatGPT generates a response listing four or five tools with brief explanations. If your product appears, you've earned a citation — your brand is in front of an active buyer at the exact moment they're evaluating options. If you don't appear, you've been filtered out before the conversation even started.
GEO is the practice of ensuring that when AI systems compose answers like that one, they have high-quality, structured information about your product readily available to draw on.

5 steps to start doing GEO
You don't need a six-figure budget or a team of engineers to improve your AI visibility. Here are the five foundational steps any team can take.
Audit your current AI citations
Before you can improve, you need to know where you stand. Run your brand name and key product queries through ChatGPT, Perplexity, and Gemini. Are you mentioned? Are competitors mentioned instead of you? This baseline is your starting point. Tools like Visibli automate this process and give you a citation score across all three platforms.
Identify the questions AI answers in your space
AI answer engines are most influential when users ask comparison, recommendation, or 'best tool for X' questions. Map out the queries that matter in your category — 'best project management tool for startups', 'what is the cheapest CRM', 'alternatives to [competitor]' — and check which answers currently cite you and which don't.
Create structured, authoritative content
AI systems favor content that is clearly structured, factually grounded, and written with authority. This means proper heading hierarchies (H1, H2, H3), concise definitions, FAQ sections with direct Q&A format, and clear attribution (author names, publication dates, company sources). Content that answers one question well beats content that answers ten questions poorly.
Build citation-worthy source material
AI models are trained on and retrieve from content that is widely cited and linked to by other sources. This means publishing original data, research, and insights that other sites reference. It also means earning coverage in publications that AI systems trust: industry blogs, news outlets, respected directories, and review platforms. Each external reference to your content increases your citation authority.
Monitor, iterate, and repeat
GEO is not a one-time project. AI systems update their knowledge, competitors publish new content, and the queries users ask evolve. Set up ongoing monitoring for your citation score and key brand queries. When you gain a citation, analyze what made that content effective. When you lose one, investigate what changed. Treat it the same way you treat SEO: a continuous improvement cycle.
The bottom line
Generative Engine Optimization is not a replacement for SEO — it's an extension of it. As AI answer engines become a primary discovery channel for products, services, and information, the brands that invest in GEO early will have a structural advantage over those that don't.
The good news: it's not yet crowded. Most brands have not seriously audited their AI citations or built GEO into their content strategy. Starting now puts you ahead of the curve.
