TL;DR Summary:
AI Clicks Stay Tiny: A case study estimates AI Overviews and AI Mode generated just 0.9% click-through, signaling that rising impressions may not translate into website traffic.AI Overviews Dominate: Google reportedly shows AI Overviews on 80% of searches, making impression-to-click trends more important than impression growth alone.Search Console Gets Smarter: New multi-select filters for devices and countries simplify cross-market reporting and eliminate tedious manual comparisons.Policy Shifts Arrive: EEA site reputation actions are no longer enforced, while a shared AI-training opt-out signal remains proposed but inactive.AI Overviews CTR Study Reveals 0.9% Click Signal | Week of November 8 2026
No new Google core update was confirmed this week; the last confirmed update remains the September 2026 spam update, which finished October 8. The most significant development is a small but widely discussed AI Overviews CTR study from Cyrus Shepard, which puts a hard number on how little traffic AI Overviews send back to websites. Search Console also picked up new filtering tools, and Google formally began notifying EEA sites about a quiet policy change on manual actions.
The AI Overviews CTR Study and What 0.9% Means
Cyrus Shepard published a case study on LinkedIn using Google’s opt-out controls to remove a site from AI Overviews and AI Mode, then compared traffic before and after. He found AI Overviews and AI Mode produced an estimated click-through rate of about 0.9%. When the site opted out, AI impressions fell to zero immediately, and regular web result clicks also appeared to drop. This is one study on one site, not a platform-wide audit, so treat the 0.9% figure as a data point, not an industry average. It still gives publishers a concrete number to compare against their own Search Console impressions.
AI Overviews Now Cover 80% of Searches
The November 2026 Google Webmaster Report states AI Overviews now appear on 80% of Google searches, including queries with typos and ones returning no results. Combined with Shepard’s 0.9% click-through estimate, this means a large share of search volume is generating impressions without proportional visits. Site owners should stop assuming impression growth in Search Console reflects traffic growth, and instead check whether their impression-to-click ratio has moved since AI Overviews expanded.
Search Console Adds Multi-Select for Devices and Countries
Google added the ability to select multiple device types at once in the Search Console performance report, extending a filtering option it had already rolled out for countries. Previously, comparing data across countries meant viewing them one at a time or in side-by-side pairs; now traffic from more than one country can be combined into a single view. The device update works the same way, letting users group desktop, mobile, and tablet data instead of switching between them. This removes a manual export step for anyone building cross-market or cross-device reports.
Site Reputation Abuse Manual Actions Lifted in the EEA
Google has stopped enforcing site reputation abuse manual actions for searchers inside the European Economic Area, a change that took effect over two months before this week’s notices went out. For pages previously hit with a manual action under this policy, that action no longer affects how the pages appear to EEA users. Sites outside the EEA, or EEA sites with other manual actions, see no change. Publishers who lost visibility to a site reputation abuse penalty should check Search Console’s Manual Actions report for updated status specific to EEA traffic.
Shared AI-Training Opt-Out Signal Proposed
Google, OpenAI, Microsoft, and Anthropic said on October 30 they will honor a shared robots.txt signal, __usage_ai-training, indicating whether a site’s content can be used to train generative models. The signal comes from an IETF Internet-Draft authored by Anthropic’s Kevin Kelley. None of the four companies has turned on enforcement yet, and Google and Microsoft are not expected to start until 2027. Site owners don’t need to change robots.txt files yet, but should watch for official rollout guidance before assuming the signal is active.
Google’s Earnings Show AI Spending Pressure
The same webmaster report noted Google posted 25% revenue growth to $127.6 billion but missed Wall Street profit expectations, citing heavy AI infrastructure spending and slowing growth in core search advertising. This is financial context rather than a ranking factor, but it signals continued investment in AI search features like AI Overviews, which supports the 80% coverage figure above and suggests the click-through dynamics in Shepard’s study are unlikely to reverse soon.
What to do this week
Pull your Search Console impressions and clicks for the last 90 days and check whether your impression growth has outpaced click growth, which would suggest AI Overviews exposure similar to the pattern in the Cyrus Shepard AI Overviews study. Tools like Measuremate can automate this impression-versus-click comparison by connecting directly to GA4 and BigQuery, flagging anomalies so you don’t have to pull and compare 90-day Search Console exports by hand.
Open Search Console’s Manual Actions report and filter by EEA traffic if your site previously had a site reputation abuse action; confirm whether the notice has arrived.
Test the new multi-select filters in Search Console’s performance report by combining your top 3 markets or device types into one view to see if patterns change your current reporting conclusions.
Check your site’s current robots.txt file and hold off on adding any AI-training opt-out directives until Google, OpenAI, Microsoft, or Anthropic publish implementation guidance for __usage_ai-training.
