AI Overview is Google's generative AI answer that appears at the top of Search Engine Results Pages for many queries, presenting a summary with citations to 1–5 source web pages.
Launched as "Search Generative Experience" (SGE) in 2023 and rebranded to "AI Overview" in 2024, AI Overviews now appear on a significant fraction of Google queries — heaviest on informational and "best X for Y" commercial queries.
For sites that are cited as a source, AI Overview drives brand exposure but typically lower direct CTR than a traditional rank-1 organic result (users get the answer in the summary). For sites not cited, AI Overview cannibalizes organic CTR. Recovering visibility means optimizing for citation: definitional content with TL;DR leads, H2 structure, tables, FAQ blocks, citable statistics with year, and E-E-A-T signals.
AI Overview citation patterns overlap heavily with Perplexity, ChatGPT Search, and Claude citation patterns. Optimizing for one usually helps with the others.
