PM AI Search
(2026 Edition)
AI search products live or die on citations — since users need a reason to trust a synthesised answer over a source list — and on retrieval quality, which matters more than model quality for most queries; PMs judge success by query resolution rate, citation click-through, and hallucination rate, while Perplexity, ChatGPT, and Google's AI Overviews slowly pull comparison and research queries away from classic search.

FAQ
Is AI search taking share from Google?
Slowly but measurably. Perplexity, ChatGPT, and Google's own AI Overviews handle some queries traditional search historically owned (comparisons, summaries, research). But transactional and navigational queries still go to classic search. The split is real; the total pie is growing.
