How does Gemini use Google Search grounding?
Google Search grounding lets Gemini analyze a prompt, decide whether Search can improve the answer, run searches, process results, and return grounding metadata with sources.
How do pages appear in Google AI Overviews or AI Mode?
Pages need to be indexed and eligible to appear in Search with a snippet. There are no special extra technical requirements beyond solid Search fundamentals.
Does Gemini require special AI schema or llms.txt?
No. AI Overviews and AI Mode do not require special schema.org markup, machine-readable files, or AI-specific text files.
What is query fan-out and why does it matter?
AI Overviews and AI Mode can issue multiple related searches across subtopics and data sources. That means pages should cover comparison, use-case, and entity questions comprehensively instead of targeting one narrow keyword.
What should I fix first for Gemini visibility?
Start with indexability, snippet eligibility, crawl access, internal links, visible text, structured data that matches page content, and current Business Profile or Merchant Center information.
