THE SHORT VERSION
What is generative engine optimisation?
Generative engine optimisation (GEO) is the work of getting your brand cited and recommended inside AI-generated answers, from ChatGPT and Claude to Google's AI Overviews. It's the next layer on top of SEO, not a replacement for it. Traditional SEO gets you ranked. GEO gets you quoted.

| The job | Get ranked | Win the answer | Get cited and recommended |
| Optimised for | Google's index | Featured snippets, 'people also ask', voice | ChatGPT, Claude, Gemini, Perplexity, AI Overviews |

HOW IT WORKS
How we get you cited
-
AI visibility audit
Where do you show up now, across which engines, for which questions. You can't fix what you can't see.
01 -
Technical foundation
Schema, structured data, crawlability, clean architecture. We make sure AI can read you and trust you.
02 -
Authority content
Expert-led, answer-first content that earns the citation, not just the click.
03 -
Digital PR and citations
Brand mentions across the trusted sources AI learns from. The new backlinks.
04 -
Multi-format amplification
One expert recording, re-cut across the formats each AI engine prefers. See the next section.
05 -
Track and refine
We measure your share of voice across each AI engine, how often you're cited, your brand mentions, and the enquiries that come from AI answers. Then we double down on what's working.

THE 21 DEGREES CONTENT ENGINE
One recording. Four formats. Four AI engines.
Here's the bit most agencies don't have. Different AI engines trust different sources. So we don't make one blog and pray. We film your experts once, then cut that single recording into the exact formats each engine pulls from. This page you're reading is the method in action.
- 01
Create
Record long-form video or audio with your experts. The dense, genuinely useful source asset. Recorded once, re-cut everywhere.
- 02
Mark up
Transcribe it, mark it up with schema, publish it with footnoted stats, quotes and source links.
- 03
Distribute
Push the video to YouTube, hand the assets and stats to PR, earn the coverage.
- 04
Amplify
Cut it into short social clips. Post fast, post often. Recency counts.
Which engine pulls from what, the 21 Degrees view:
- LLM target
Claude
Technical, peer-reviewed and government sources.
- LLM target
Google Gemini
Brand-owned websites and official properties.
- LLM target
ChatGPT
Directories and Wikipedia.
- LLM target
Perplexity
Recent content, Reddit and social, with a heavy weighting on the last 30 days.

What our clients say
Before 21 Degrees, we were not appearing for AI searches through LLMs or Google, now we're getting new leads from ChatGPT every day. They didn't just improve our SEO. They transformed our entire business trajectory. We've had to hire two new staff to handle the enquiries.

What is generative engine optimisation (GEO)?
GEO is the practice of getting your brand cited and recommended inside AI-generated answers, across ChatGPT, Claude, Gemini, Perplexity and Google AI Overviews. It builds on SEO. Where SEO gets you ranked in the links, GEO gets you quoted in the answer.
-
What's the difference between GEO and AEO?
They're two lenses on the same job. AEO (answer engine optimisation) is the granular bit: winning the direct answer, the snippet and the voice result for specific questions. GEO is broader: making sure your brand is regularly cited and recommended across the AI engines. Most brands need both.
-
Is GEO just SEO with a new name?
No, but it's built on SEO, not instead of it. The fundamentals still apply: a fast, crawlable site, content that answers real questions, and authority earned across trusted sources. GEO adds schema, citation building and AI visibility tracking on top. Anyone selling GEO without the SEO groundwork is selling you a roof with no walls.
-
Is SEO dead?
No. Search demand is higher than ever; it's just spread across more surfaces. People click less and ask more. SEO is the foundation every GEO campaign is built on. Calling it dead is, frankly, laughable.
-
How do you track AI visibility?
We measure where and how often your brand shows up across the AI engines for the questions your customers actually ask, then tie that back to the work that moved it. You can't manage what you can't measure, so tracking is the first thing we set up, not the last.
-
How long until GEO works?
Brands with existing authority can start appearing in AI answers within a few weeks of focused work. Starting from scratch, expect a few months before meaningful traction, because authority compounds over time.
