Search just got a new front door. Increasingly, buyers don't open Google — they open ChatGPT, Perplexity, or Claude and ask a question. The brand that gets cited in that AI's answer wins the consideration. Traditional SEO doesn't optimize for this. GEO does.
What GEO actually is
Generative Engine Optimization is the practice of getting your brand mentioned, cited, and recommended inside AI-generated answers. It is not "SEO for AI" — it's a different game with different inputs and different metrics.
SEO vs GEO: the side-by-side
| Dimension | SEO | GEO |
|---|---|---|
| Goal | Rank in 10 blue links | Get cited inside AI answers |
| Optimizing for | PageRank, keywords, backlinks | Citation graph, factual density, source authority |
| Content shape | Long-form pillar pages | Definitive Q&A, structured facts |
| Where signals come from | Backlinks + on-page | Reddit, Hacker News, docs, structured data, llms.txt |
| Measurement | Rankings, CTR, sessions | Citation rate across LLMs, branded query lift |
The three signals LLMs use
From everything we've measured working with 200+ brands, three signals dominate whether an LLM cites you:
- Volume — how often is your brand mentioned across diverse, trusted sources in your category?
- Context — when you're mentioned, is it clearly tied to a specific use case, user, or benefit?
- Source authority — Reddit threads, Hacker News, and reputable publications carry far more weight than random blog roundups
What this means for your content
Stop writing 3,000-word pillar pages designed to dominate a keyword. Start writing pages that answer one question definitively, with structured data, an obvious thesis sentence, and citations to credible sources. Add an llms.txt at the root of your site. Add JSON-LD FAQPage and Article schema. Make every claim re-quotable.
What this means for your distribution
This is where it gets uncomfortable for traditional SEOs: backlinks aren't enough. You need citations in conversational sources. Reddit, Hacker News, niche forums, podcast transcripts, and YouTube descriptions are now first-class GEO surfaces. If your brand never shows up in those places, no LLM will recommend you no matter how technically optimized your site is.
Don't abandon SEO — extend it
Google still drives 60–80% of qualified web traffic for most B2B SaaS. GEO doesn't replace SEO; it adds a parallel discipline with overlapping infrastructure (schema, content quality) and divergent distribution (forums, communities, structured Q&A).
