Short answer
Gemini answers are frequently grounded in retrieved sources. Optimizing for that means making your claims verifiable, your entities unambiguous and your pages consistent with each other — so a system checking a statement against your site finds clear support rather than contradictions.
What grounding changes
An ungrounded answer comes from what a model absorbed during training. A grounded answer is assembled from documents retrieved at the moment of asking. The second kind is where optimization has purchase, because your live pages are part of the evidence.
That reframes the goal. You are not trying to be memorable to a model; you are trying to be the clearest available evidence for a claim at the moment someone asks about it.
What makes a page good evidence
- 01A checkable claimA specific statement in a single sentence beats a paragraph of qualifications. Vague content cannot support anything.
- 02A visible dateUndated claims are hard to trust. "As of 2026" carries weight that "currently" does not.
- 03A named sourceWhere a claim comes from your own data or method, say so explicitly and describe the method.
- 04Internal agreementIf three of your pages describe the same thing differently, none of them is reliable evidence.
- 05Unambiguous entitiesOne canonical name per concept, introduced explicitly rather than switched silently.
The consistency audit nobody runs
Search your own site for the three or four concepts that matter most to your business and read how each is described on different pages. Most sites find genuine contradictions within minutes — a definition that drifted, a figure that was never updated, a product described two different ways. It is unglamorous work and unusually cheap for the return.
- One canonical description per concept, reused rather than rewritten.
- A definitional home page for each core concept, linked from every mention.
- Figures dated, and stale ones removed rather than left to age.
- Organisation details identical everywhere: name, description, contact route.
- Structured data that matches the visible page rather than an aspiration.
Technical prerequisites
Grounding requires retrieval, and retrieval requires ordinary discoverability: server-rendered HTML, sensible robots rules, correct canonicals, a current sitemap. See technical SEO for the full pipeline a page has to survive.
