We Opted Out of Google AI Search – Here's What Happened
A publisher opted out of Google's AI search features for 28 days and found AI search impressions (500–1000 daily, about 10% of total search impressions) dropped to zero within an hour, then returned after opting back in. Statistical analysis estimated an AI search CTR of about 0.9% (range 0.7%–1.1%), more than double the site's roughly 0.4% overall Google CTR, and a small but significant ~2.3% halo effect on regular organic CTR. Combined, the authors estimate Google's AI search was responsible for about 23% of total search clicks to the site, though they caution the single-site results are directional only.
