Why does Google use AI Overviews now?

Google uses AI Overviews largely to keep users inside Google Search as competitors like ChatGPT and Perplexity pull away traffic for informational and research style queries. Rather than sending a user to five different articles, Google can synthesize an answer and keep the session on its own platform.

The feature also reflects a real shift in how people search. More users now type full questions instead of short keyword phrases, and a synthesized answer often satisfies that intent faster than scanning multiple pages.

Google frames AI Overviews as a better user experience, and internal data it has shared publicly does show increased search usage in markets where the feature is live, though the tradeoff for publishers has been fewer clicks per impression.
