Buy side (UA, advertisers, DSPs): Inbound acquisition teams must treat AI search citations as brand-lift catalysts rather than isolated referral sources, as opting out appears to cannibalize standard search click-through rates. Marketers should model AI search visibility into overall organic pipeline health rather than expecting high direct CTRs from AI snippets alone.
Sell side (publishers, monetization, SSPs): Publishers weighing content blocking against AI scrapers face a painful monetization trade-off, as exiting Google AI results can directly reduce core organic traffic and ad impressions. Media companies should pause sweeping AI opt-outs until they quantify whether content protection offsets lost on-site ad revenue.
What to watch: Run small-scale directory-level A/B tests on AI opt-out tags to quantify standard organic CTR decay before considering site-wide crawler bans.

Traditional organic clicks declined after a website opted out of Google’s AI search features, according to a small case study shared by SEO consultant Cyrus Shepherd. AI impressions also fell to zero.

Why we care. AI citations may drive more clicks than direct AI referrals show. Measuring only AI referral traffic could miss some of that value.

What happened. Shepherd shared three findings on LinkedIn:

AI impressions fell to zero immediately after the site opted out.
Estimated AI click-through rate was 0.9%, based on changes in overall clicks before and after opting out.
Traditional organic clicks also declined after AI features were disabled.

The halo effect. Shepherd called this a possible “Search SERP Halo Effect.” He believes appearing in both AI answers and traditional search results could build trust and increase clicks. An AI citation could help a website earn more clicks from its regular organic listings, even when users don’t click the AI answer.

About the data. Shepherd described the test as small and cautioned that results may vary. He didn’t disclose the site’s traffic volume, test dates, size of the organic click decline, or opt-out method. These missing details make it difficult to draw firm conclusions.
