How to optimize for Gemini: Google's other AI search engine

Questions this guide answers

• How do I optimize for Gemini?
• How does Gemini differ from Google AI Overviews?
• What are Gemini's ranking signals?

Direct answer

Gemini is Google's standalone AI assistant that uses Google's web index plus Gemini's reasoning model to answer queries. Gemini differs from Google AI Overviews in four ways: Gemini is conversational and multi-turn while AIO is single-answer; Gemini integrates with Google Workspace for personalized context; Gemini emphasizes multimodal queries more than AIO; and Gemini's grounding controls enforce stricter source verification for some query types.

Optimization for Gemini is roughly 80% identical to optimizing for Google AI Overviews (same index, same crawler stack), with 20% Gemini-specific work for multimodal content and conversational query patterns. If your brand is well-optimized for AIO, you are already most of the way there.

Why Gemini matters separately

Per Similarweb data through January 2026, Gemini accounts for roughly 18% of AI-search-style query volume. This is materially larger than the 5 to 10% figures circulated in earlier 2025 commentary, and large enough that Gemini deserves engine-specific work in any multi-engine AEO program. The reasons to optimize for Gemini specifically:

• Google ecosystem leverage: Gemini is integrated into Gmail, Workspace, Android, and Chrome.
• Multimodal preference: Gemini is increasingly used for image-driven queries (photo of a product, screenshot of an issue).
• Workspace integration: B2B buyers using Google Workspace get Gemini suggestions as they work.
• Future ecosystem expansion: Gemini is likely to be deeply integrated into Android, Pixel devices, and other Google services.

How Gemini retrieves and synthesizes

Gemini shares architecture with Google AI Overviews. A user asks a question (text, image, voice, or multimodal). Google's search index retrieves candidates. Gemini synthesizes an answer with optional source citations. For Workspace queries, Gemini may also pull from the user's own Drive or Gmail context.

Same crawler stack as AIO: Googlebot crawls for Google's index; Google-Extended is the training opt-out flag. Gemini handles image plus text queries natively. When a user is logged into Google Workspace, Gemini may pull from their personal context (subject to permissions). Google enforces stricter source verification (grounding controls) for factual, YMYL, and news query types.

The four unique signals

These four signals drive Gemini-specific optimization.

How Gemini differs from Google AI Overviews

Gemini and AIO share most signals. The differences are at the edges of optimization. Do not over-invest in Gemini-specific work until your AIO foundation is strong.

A 5-step Gemini audit

Run this audit alongside your AIO audit.

• Verify Google ranking foundation in Search Console.
• Multimodal audit: image alt text, captions, image-text relationships on top 30 pages.
• Conversational structure audit: H2 sections, FAQ count, related links.
• Workspace-context query identification: 3 to 5 relevant queries.
• Run 10 priority queries in Gemini, including 2 to 3 multimodal queries with images.

Common Gemini optimization mistakes

Five mistakes show up repeatedly.

• Treating Gemini as a totally separate optimization. Build the AIO baseline first.
• Ignoring multimodal optimization. Brands with strong text content but weak image labeling miss multimodal queries entirely.
• Ignoring Workspace context for B2B. Workspace plus Gemini buyers are often the highest-conversion B2B segment.
• Underinvesting because perceived share is small. Recent measurement places Gemini's share materially higher than older estimates.
• Confusing the Gemini consumer chatbot with the Gemini API. Optimization here covers the consumer chatbot.
