What Google actually says
Google says its existing SEO best practices remain relevant for AI Overviews and AI Mode. A page must be indexed and eligible to appear with a snippet. Google also says there is no additional AI-only technical requirement, special schema, or machine-readable AI file needed for inclusion.
What matters regardless of the acronym
- Important information is crawlable, indexable, and present in HTML text.
- The company, founder, services, customers, and service area are described consistently.
- Pages answer real customer questions directly and accurately.
- Claims are supported by useful detail, examples, primary sources, or credible independent context.
- Structured data matches what a visitor can actually see.
- Content is updated when facts, platform rules, or services change.
