What is Query Fan-Out?
When an AI system expands one question into many sub-queries behind the scenes to gather sources. Broad, well-structured topic coverage wins fan-out because more sub-queries land on your pages.

Topical Authority
The depth and breadth of expertise a site demonstrates on a subject, earned by comprehensively covering a topic and interlinking it rather than publishing scattered pages. Engines reward the site that most completely owns a subject with rankings across many related queries.
Query Synthesis
How AI systems compose an answer from multiple retrieved passages rather than one page. Synthesis rewards sites that own several quotable passages across a topic, not a single good page.
Conversational Search
Multi-turn search where follow-up questions inherit context from earlier ones. Pages that define entities clearly and cover adjacent subtopics get pulled into longer answer threads.
Answer Engine Optimization (AEO)
Answer Engine Optimization is the practice of structuring pages so answer engines and AI assistants can extract, trust, and quote them: a direct definition up top, scannable steps, quotable facts, and FAQ or Article schema behind them.
Generative Engine Optimization (GEO)
Generative Engine Optimization improves how often a brand or page is cited inside AI-generated answers. It combines classic SEO (crawlability, relevance) with quotability: clear facts, named entities, sources, and machine-readable structure.
AI Overviews
Google’s AI-generated summaries at the top of some results pages. They synthesize multiple sources and link to them, which can reduce clicks to publishers even when a page ranks well organically.
