AI Overviews — Google's AI-generated summary appearing above traditional organic results for many queries — have expanded their footprint significantly through 2025 and into 2026, and their impact on organic click-through rate has become one of the most discussed topics in SEO.
Broad informational queries, particularly ones with a clear, extractable answer, tend to see the most significant click-through rate reduction when an AI Overview appears, since a meaningful share of searchers get their answer directly without clicking through to any source at all. Commercial and navigational queries are generally far less affected.
Being cited as a source within an AI Overview, even without generating a direct click, likely carries some brand visibility and trust value, similar to how a featured snippet's impression, even unclicked, has some value beyond direct traffic. This overlaps directly with AEO and GEO strategy.
The right response to AI Overviews is not panic about traffic loss on every query — it is recognising which specific query types are affected and adjusting content strategy for those specifically, while continuing to capture clicks on the queries that still reliably deliver them.
Not directly and explicitly in all cases, though impression and click-through rate patterns for specific queries can suggest where this is likely occurring, particularly for simple, factual informational terms.
No — informational content still holds real value for both AEO/GEO citation and complex queries an AI summary cannot fully satisfy, but the expected click-through rate for simple factual queries should be recalibrated realistically.
Based on the trend through 2025 and 2026, continued expansion seems likely, making the adaptation covered here an ongoing strategic consideration rather than a one-time adjustment.

Track click-through rate by query type, not just overall — informational queries with an AI Overview present need a different strategy than commercial or navigational queries, which remain largely unaffected.
