How to Rank in Gemini
To be cited in Gemini, your pages need to be in Google's Search index, and you shouldn't block Google-Extended, because Google says that token controls whether your content can be used for grounding in Gemini Apps ([Google](https://developers.google.com/crawling/docs/crawlers-fetchers/google-common-crawlers)). Then publish clear, specific pages. When Gemini shows sources, it shows them through a Sources button or inline links (Google).
Facts are from Google's documentation, accessed 30 Oct 2026. Recommendations marked "our view" are interpretation.
How does Gemini use the web?
Google describes "grounding" as providing content from the Google Search index to the model at prompt time to improve factuality and relevance (Google). So for web facts, Gemini Apps draw on the same index that powers Google Search.
| Element | What Google says |
|---|---|
| Index | Google Search index, used for grounding at prompt time (Google) |
| Control | Google-Extended governs training and grounding use in Gemini Apps (Google) |
| Sources display | Sources button at the bottom or inline, when available (Google) |
| Not always | Not all responses include sources (Google) |
| Quotes | Large direct quotes from a webpage get a link in sources (Google) |
Step 1: Are you in Google's index?
If Google hasn't indexed a page, it can't ground Gemini. Use Search Console URL Inspection and fix crawl or indexing issues (Google). Remove accidental noindex (Google).
Step 2: Should you allow Google-Extended?
Google-Extended has no user agent of its own; it's a robots.txt token. Google says it controls whether content may be used to train future Gemini models and for grounding in Gemini Apps and Vertex AI, and that it doesn't affect inclusion or ranking in Google Search (Google).
| Choice | Effect (per Google) |
|---|---|
| Allow (default) | Content may be used for Gemini training and grounding |
| Disallow | Excluded from those uses; Google Search unaffected |
Our view: if being cited in Gemini Apps matters to you, blocking Google-Extended works against it, because it also covers grounding. Many publishers block it to opt out of training; weigh both effects.
Google also says it intends to support the AIPREF training-preference signal (user-agent: __usage_ai-training) in early 2027 (Google). Watch for changes.
Step 3: Do your pages answer specific questions?
Our view: grounding retrieves pages relevant to the prompt, so precise pages match better. Google's general advice also applies: helpful, reliable, people-first content (Google).
- [ ] Direct answer near the top
- [ ] Question-style headings
- [ ] Facts in text (not only images)
- [ ] Clear dates and authorship
- [ ] One topic per page
Step 4: Are your entity facts consistent?
Gemini responses about your brand rely on what the index says. Keep your name, category and key facts consistent across your site and profiles, and add Organization structured data (Google).
Step 5: How do you test Gemini?
- Run 20–50 buyer prompts in the Gemini app (prompt library).
- Record whether a Sources button appears and which links it lists.
- Note whether you're mentioned without a source (possible training knowledge).
- Re-run monthly; Gemini can regenerate or vary answers.
| Prompt | Mentioned? | Sources shown? | Your URL cited? |
|---|---|---|---|
| "best X for Y" | Yes | Yes | No (roundup cited) |

How is Gemini different from AI Overviews?
| Gemini Apps | AI Overviews / AI Mode | |
|---|---|---|
| Where | Gemini app | Google Search |
| Control token | Google-Extended affects grounding (Google) | Google-Extended doesn't apply; use snippet controls (Google) |
| Reporting | None for publishers | Included in Search Console Performance, Web type (Google) |
| Sources | When available (Google) | Supporting links |

What does a worked plan look like?
Illustrative example: a payroll software company is mentioned by Gemini for "payroll for small businesses in Germany" but never shown in sources.
- Check robots.txt. It finds a blanket
Google-Extendeddisallow added last year to opt out of training. The team weighs training opt-out against grounding citations and decides to allow it for the product and help sections only. - Check indexing. Two key help pages are canonicalised to a generic page; fixing canonicals gets them indexed (Google).
- Rewrite. The German payroll page now opens with a direct answer, a table of supported contracts and a dated "last updated" line.
- Re-test after recrawl and log Sources results.
The robots.txt choice is a business decision, not just a technical one. Document who made it and why.
What doesn't help?
- Special "AI files" or extra schema: Google says none are needed for its AI search features (Google)
- Blocking Google-Extended and expecting Gemini citations
- Thin pages made for AI
Checklist
- [ ] Key pages indexed
- [ ] Google-Extended decision made and documented
- [ ] Answer-first content
- [ ] Organization markup and consistent facts
- [ ] Monthly Gemini tests
