답변 엔진

An Answer Engine responds directly to a question instead of presenting a list of links to documents. AI Overviews, ChatGPT Search and Perplexity all fall within this broad category. As answer engines become more common, users can obtain information without visiting a website, increasing the importance of zero-click search. This structural change makes click-based traffic metrics alone insufficient to describe marketing performance. More organizations consequently track brand mention frequency and AI citations alongside click-through rates.
