Google AI Overviews are AI-generated summaries that appear above organic search results for certain informational queries. Google reads multiple web pages, extracts the most relevant passages, and synthesises a combined answer with source links. Pages that rank in the top 12 organic results and have clear, direct answers are most likely to be cited. Understanding this process helps you write content that Google can easily find and use.
