What is GEO?
Generative Engine Optimization explained.
Gartner estimates traditional search engine volume will drop 25% by 2026 as AI assistants take over. Optimizing only for Google means missing the fastest-growing channel. GEO is the discipline that fixes that.
TL;DR
- GEO = optimize to appear in the answers LLMs give (ChatGPT, Claude, Perplexity, AI Overviews, Copilot).
- SEO puts you in a list of 10 links. GEO puts you inside the synthesized answer.
- Tactics change: citability > backlinks. Schema.org > keyword stuffing. Brand mentions > anchor text.
- Measured by citation rate: how many LLM answers mention your brand when a potential customer asks.
- It doesn't replace SEO. It complements it. Doing only one of the two means missing half the game.
The problem: your customer no longer goes to Google
Five years ago, when someone wanted to choose invoicing software, a dental clinic in Vigo, or a solar panel installer, they typed the question into Google. They saw 10 blue links. They clicked 3. They picked up the phone.
Today, a growing share types the same question into ChatGPT, Claude, or Perplexity. Gartner estimates traditional search volume will drop 25% by 2026. The LLM gives a synthesized answer, cites 2 or 3 brands, and the user picks up the phone without going through Google.
If your brand isn't in that answer, you don't exist for that customer. And all your SEO work from recent years — ordered keywords, careful backlinks, 2,000-word content — doesn't matter because that user never lands on the SERP where you rank fifth.
GEO (Generative Engine Optimization) is the set of tactics that ensure your brand is cited by generative engines when a potential customer asks a question you should appear in.
The generative engines that matter in 2026
It's not just ChatGPT. These are the six LLMs whose traffic you need to start measuring today.
| Engine | Company | Positioning | Share / use |
|---|---|---|---|
| ChatGPT | OpenAI | consumer | leader (~55%) |
| Gemini | consumer + Workspace | 2nd (~27%) | |
| Claude | Anthropic | B2B / dev | growing |
| Perplexity | Perplexity AI | search-first | research niche |
| AI Overviews | embedded in SERP | embedded in Google | |
| Copilot | Microsoft | Bing + Edge | enterprise |

The 6 GEO tactics that actually move the needle
No magic. Discipline. These six practices, sustained for 90 days, lift your citation rate measurably.
Brand mentions without links
LLMs train on the open web. Show up on Reddit, in HN threads, in LinkedIn posts, in transcribed podcasts, in local press. You don't need backlinks — you need textual presence.
Aggressive schema.org
Organization, SoftwareApplication, FAQPage, Product, BreadcrumbList, Service. Structure your site as a database so the LLM understands who you are, what you do, who you serve, where, for how much.
Answerable content
LLMs synthesize, they don't list. Write in direct question-answer format. One sentence per idea. No kilometric paragraphs. Well-structured Markdown with semantic H2/H3.
Your own citable data
Customer surveys, industry benchmarks, public calculators, studies with real samples. LLMs love citing the original source — not the blog that summarizes it.
Constant freshness
A page updated 3 months ago beats one from 2 years ago. LLMs notice via crawlers and re-indexing. Publish something new every week on the same topic cluster.
Entity consistency
Your name, location, offering, and category must be exact across every source (site, GMB, LinkedIn, press). LLMs treat you as a single entity when all signals line up.
How is GEO measured in practice?
The headline metric is citation rate: given a set of queries your potential customers would make, what percentage of the LLM's answers mention your brand.
The process, step by step:
- Generate 20-100 queries representative of your industry (not including your company name — we want the LLM to cite you spontaneously).
- Run each query against the LLMs that matter (at minimum ChatGPT and Perplexity).
- Count how many answers mention your brand, your domain, or your product.
- Divide by total queries. That's your
citation_ratefrom 0 to 1. - Repeat every week. Measure whether it goes up or down. Iterate tactics.
Rowan Growth automates all this: an AI trained on your business generates the questions from your domain, checks them against multiple assistants, and the result lives in a dashboard with history and alerts. When your presence rises, you know which tactic worked.

FAQ
Questions about GEO.
01 What is GEO (Generative Engine Optimization)?
GEO is the discipline of optimizing your brand to appear and be cited by generative AI engines — ChatGPT, Claude, Perplexity, Google AI Overviews, Microsoft Copilot. Unlike classic SEO, you're not trying to rank in a list of 10 links — you're trying to be inside the synthesized answer the LLM gives the user.
02 How does GEO differ from traditional SEO?
SEO optimizes for appearing on a results page (SERP) with 10 ordered links. GEO optimizes for the LLM to mention you when a user asks a question. SEO depends on keywords, backlinks, and domain authority. GEO depends on citability, semantic structure, named entities, and presence in sources LLMs read (Wikipedia, Reddit, topical forums, press).
03 How much traffic already comes from LLMs in 2026?
Gartner estimates traditional search engine volume will drop 25% by 2026 as AI assistants take over (Gartner, 2024). There's no official sector-level data for Spain yet, but the trend is clear and, from what we see with our clients, it moves faster in tech, health, and B2B SaaS. On top of that, users arriving from ChatGPT tend to have higher buying intent: they've already qualified the problem with AI before looking you up.
04 How do you measure whether you show up in ChatGPT?
Generate queries your potential customers would make (how to choose X, best Y, alternatives to Z), ask the LLM, and check whether your brand appears in the answer or in businesses_mentioned. Rowan Growth automates this weekly cross-LLM check and gives you a citation_rate from 0 to 100%.
05 What signals does an LLM look at to cite a brand?
Content freshness (how much has been published recently about the brand), presence in training data (sites with authority), mentions in Reddit/HN/niche forums, well-structured schema.org, brand mentions without links in press, and named entity consistency (so the LLM knows exactly what you are, where, and what you do).
06 Does GEO replace SEO?
No. It complements it. SEO brings you the bulk of today's organic traffic (Google still dominates by far). GEO brings you traffic from AI answers — small today, but the fastest-growing channel: Gartner estimates a 25% drop in traditional search by 2026 (Gartner, 2024). Optimizing only for SEO misses the fastest-growing channel. Optimizing only for GEO misses the bulk of current traffic.
