Generative engine optimisation
Generative engine optimisation for ecommerce brands
A generative answer is not extracted from one page — it is synthesised from several. You cannot own that sentence, but you can decide how much of it comes from your facts, and whether your brand is named inside it.

How synthesis works
The model is not choosing a winner. It is reconciling sources
When several sources agree, the shared fact becomes the answer and the clearest source gets cited. When they disagree, the model hedges, softens the claim or drops the detail entirely — and a hedged answer rarely names a brand.
- Agreement raises confidence; contradiction lowers it.
- Specific figures survive compression better than adjectives.
- The clearest phrasing of a shared fact tends to be cited.
- Silence off-site is treated as absence of evidence.

Entity consistency
One brand, one description, everywhere
Generative systems build an internal picture of your brand from every source they see. Inconsistent naming, positioning or specifications fragment that picture and reduce the confidence needed to recommend you.

The GEO levers
Five things that actually change generative output
Canonical fact layer
A single authoritative place on your site for every fact a model might need — specifications, compatibility, sizing, shipping scope, warranty — written as text and mirrored in structured data.
Quantified claims
Replace comparative adjectives with figures and thresholds. Numbers survive compression into a synthesised sentence; adjectives get discarded.
Stated constraints
Explicit conditions and exclusions give the model the confidence to make a specific recommendation instead of a generic one.
External corroboration
Retailer listings, editorial coverage and comparison sites repeating the same facts, so agreement is available to be found.
Contradiction removal
Auditing where your own site, feeds, marketplaces and partners disagree — then fixing the source of truth rather than patching one page.
Contradiction audit
Where ecommerce brands contradict themselves
Illustrative audit output. Each conflict costs confidence at exactly the moment a recommendation is being formed.
| Fact | Own site | Third-party sources | State |
|---|---|---|---|
| Product naming | Model + variant | Variant only | Conflict |
| Material specification | Stated in text | Different value | Conflict |
| Shipping markets | 12 markets | 12 markets | Aligned |
| Warranty period | 24 months | 12 months | Conflict |
| Price band | Structured data | Matches | Aligned |
| Category positioning | Performance | Lifestyle | Drift |
Outcome
What a resolved entity looks like in a generated answer
When facts agree and constraints are explicit, the answer becomes specific — and specific answers name brands.

GEO and AEO
Two disciplines, one foundation
AEO makes a passage extractable. GEO makes your facts survive compression across many sources. Most programmes need both, but the sequencing differs by category.

Measurement
Confidence is inferred, so we track it indirectly
There is no confidence metric to read. We track how specifically answers describe the brand, how often owned facts are reused, and how many contradictions remain open.

FAQ
GEO questions
GEO is the practice of influencing answers that are synthesised from multiple sources rather than extracted from one page. Because the answer is newly composed, the levers are entity consistency, quantified claims, explicit constraints and external corroboration — everything that raises a model's confidence in your facts.
AEO targets extraction: making one passage answer one question completely so it can be lifted and attributed. GEO targets synthesis: making your facts agree across every source a model might see, so they survive compression into a new sentence. They share a technical foundation and diverge in emphasis.
No. You can change the evidence available and how consistent it is. In practice that is what moves output from a vague, brand-free answer to a specific recommendation that names sources — but the sentence itself is always composed by the model.
Conflicting facts force the model to hedge. A hedged answer drops the specific detail — and usually the brand name with it. Resolving contradictions at the source of truth, including feeds and marketplace listings, is often the highest-impact GEO work available.
It requires corroboration, which sometimes comes from editorial coverage but often comes from unglamorous work: correcting retailer listings, aligning marketplace specifications, updating directory entries and making sure partners describe your products the way you do.
By tracking how specifically monitored answers describe the brand, what share of synthesised claims trace back to owned pages, how many cross-source contradictions remain open, and how many generative surfaces mention the brand at all.
