Generative Engine Optimisation
Being the source a generative engine reaches for
Generative Engine Optimisation is the practice of structuring an organisation’s published information so that generative AI systems retrieve it, represent it accurately, and cite it when answering related questions. It operates at the level of the entity and the source rather than the individual page.
The mechanism matters. When someone asks an assistant a commercial question, the system typically runs one or more retrieval queries, pulls a set of candidate sources, and synthesises an answer from the passages it considers most relevant and reliable. Your organisation appears in that answer only if it was retrieved, only if the retrieved passage was clear enough to use, and only if the system considered the source worth naming.
GEO addresses all three conditions. Retrieval depends on crawlability, indexation and topical authority. Usability depends on how unambiguously your content states things. Attribution depends on whether you are recognisable as a distinct, credible entity rather than an anonymous page.
Scope
What generative engine optimisation covers
GEO is a programme rather than a checklist. These are the workstreams that make up a typical engagement.
Entity definition and disambiguation
Establishing one canonical description of your organisation: legal name, alternate names, identifiers, location, services, and what you are notably good at. Then making that description consistent everywhere a model might encounter it.
Source authority development
Earning accurate mentions on sources that are themselves frequently retrieved: industry publications, professional directories, partner sites, standards bodies. A correct description on a trusted third-party source carries more GEO weight than a link on a weak one.
Factual consistency auditing
Finding and correcting places where your own materials contradict each other. Conflicting service names, outdated addresses, three different descriptions of the same offering: each of these lowers a model’s confidence in describing you.
Retrieval-friendly content structure
Ensuring the passages a model would want are complete, self-contained and unambiguous, so extraction does not distort them. Covered in depth by the Answer Engine Optimisation service.
Prompt and share-of-answer monitoring
Tracking a defined set of buyer questions across ChatGPT, Claude, Gemini, Perplexity and AI Overviews. Recording who appears, who is cited, and whether the facts returned about you are correct.
Correction of inaccurate representations
When a model states something wrong about your organisation, identifying the likely source and correcting it there. This is often an outdated directory listing or a stale third-party article rather than anything on your own site.
Method
How a GEO engagement runs
Baseline
Run the priority buyer questions across each AI system and record verbatim responses. This becomes the reference point for everything after.
Entity audit
Map every place your organisation is described, on your site and off it. Identify contradictions, gaps and stale information.
Fix the source of truth
Establish the canonical description, implement it in schema, and align the site’s own copy with it.
Propagate
Correct third-party sources, publish the material that fills genuine gaps, and pursue mentions on retrievable sources.
Re-measure
Re-run the baseline prompts on an agreed cadence and report movement against the recorded starting point.
Comparison
GEO next to the disciplines it is confused with
| Dimension | Traditional SEO | AEO | GEO |
|---|---|---|---|
| Unit of work | The page | The passage | The entity and the source |
| Goal | Rank in a results list | Be the extracted answer | Be retrieved and cited by name |
| Primary lever | Relevance and links | Structure and clarity | Authority and consistency |
| Measured by | Position, clicks, impressions | Snippet and answer capture | Share of answer, citation rate, factual accuracy |
| Typical output | Optimised pages | Structured passages and markup | Consistent entity across all sources |
| Time to effect | 2 to 6 months | Weeks to 2 months | 3 to 9 months |
Limits
What GEO cannot do
Model providers do not publish their retrieval or citation logic, and they change it. Two identical prompts issued minutes apart can return different sources. Any measurement of AI visibility is therefore a sample rather than a rank, and should be reported as one.
GEO also cannot make an organisation authoritative that has nothing to be authoritative about. If a company has no differentiated capability, no published expertise and no third-party recognition, the honest recommendation is to build some of that first. Structuring an empty claim more clearly does not make a model repeat it.
