How Much Do Google AI Overviews Reduce Organic Click-Through Rate?

Google AI Overviews reduced organic click-through rate by 61% on the queries where they appear, according to a Seer Interactive study that tracked CTR falling from 1.76% down to 0.61% on AI Overview-triggering searches. That drop has since partly reversed — Seer's tracking shows organic CTR on the same query set recovering to roughly 2.4% by February 2026, as searchers grew more comfortable scrolling past the AI-generated answer to click a source link.

The Recovery Curve

The initial 61% CTR collapse happened as AI Overviews rolled out broadly and users defaulted to reading the generated summary without looking further. The partial rebound to about 2.4% by February 2026 — still below the pre-AI-Overview 1.76% baseline in absolute click volume terms for many sites, since 2.4% of a query set that increasingly resolves without any click at all is a smaller slice of total searches — suggests searchers are treating AI Overviews more like a quick preview than a final answer for a meaningful share of queries, particularly ones requiring comparison, recent data, or a transaction.

• Pre-AI Overview baseline: 1.76% organic CTR
• Immediate post-rollout: 0.61% organic CTR (a 61% drop)
• Recovered by February 2026: roughly 2.4% organic CTR on AI Overview queries

Zero-Click Reality Is Still the Bigger Story

CTR recovery on the queries that do produce a click matters less than the share of queries that never produce a click at all. Industry tracking cited alongside the Seer Interactive figures puts the zero-click rate on AI Overview-triggering searches at 80%-83% — meaning four out of five users who see an AI Overview get what they need without visiting any website, regardless of how that remaining 17%-20% of clicks is distributed.

A page ranking #1 today on a query that triggers an AI Overview can now deliver roughly the traffic that a #3 ranking delivered before AI Overviews existed. That reframes what "ranking well" is worth for high-intent informational queries specifically, even though transactional and highly specific queries are less affected since they trigger AI Overviews less often.

What This Means for GEO/AEO Content

Content cited directly inside an AI Overview appears to retain more value than content that merely ranks below one. Reporting alongside the CTR studies found that brands cited within an AI Overview earned about 35% more organic clicks and 91% more paid clicks than brands ranking on the page without a citation — a citation functions less like a ranking position and more like a trust signal that pulls incremental clicks from both channels.

Bottom Line

Don't judge SEO performance on AI Overview-heavy queries by historical CTR benchmarks; measure citation rate within AI Overviews as a separate KPI alongside traditional ranking position, and prioritize the query types (transactional, comparison, highly specific) where zero-click behavior is lowest and a website visit is still the likely outcome. Track both metrics quarterly, since the CTR recovery curve seen between the initial rollout and February 2026 suggests the numbers are still moving as user behavior adapts.
