The rules could give publishers a clearer way to assess traffic and visibility from AI Overviews and AI Mode. - Author: GEO Search Leads - Tags: GEO Industry News The UK Competition and Markets Authority (CMA) has required Google to give publishers more detailed reporting on how people engage with their content in AI-driven Search features. The requirement covers impressions, clicks and click-through rate (CTR) when Search Content is used in features including AI Overviews and AI Mode. The change matters because publishers have had limited visibility into whether AI search results generate visits to their sites. Under the CMA's Publisher Conduct Requirement, Google must provide data that is separated from traditional organic Search reporting and broken out by publisher. Google has until 3 December 2026 to comply with the reporting requirement. ## What Google must report to publishers The CMA's [Publisher Conduct Requirement](https://assets.publishing.service.gov.uk/media/6979d0bf75d44370965520a0/Publisher%5Fconduct%5Frequirement.pdf) requires Google to provide detailed, disaggregated engagement metrics for publisher content used in its AI features. The specified measures are: - Impressions - Clicks - Click-through rate The data must be separated from organic search data and available at the publisher level. The CMA indicates that Google can provide the reporting through a platform such as Google Search Console. This distinction is important. A publisher may currently see overall Search performance, but aggregate figures do not show whether an impression or click came from a conventional web result or from an AI-generated search experience. Separate reporting should make it possible to evaluate those channels independently rather than infer AI search performance from changes in total traffic. The requirement does not mean that the new reporting is available now. Reporting ahead of the decision noted that Google had not announced additional AI click data, and the compliance deadline remains in December 2026\. Publishers should therefore avoid treating existing Search Console reports as a complete measurement of engagement with AI Overviews or AI Mode. ## The deadline and the related publisher controls Google's deadline for the data-reporting obligation is 3 December 2026\. The CMA also requires Google to offer controls that let publishers opt their content out of being used to train or ground AI systems. Google has an additional three months to roll out page-level controls, taking that part of the implementation to roughly March 2027. The CMA's measures also require Google to publish information about attribution and factuality in its AI-driven search features. Google is expected to provide compliance reporting at least every six months during the first year. | Requirement | What it means for publishers | Timing stated by the CMA | | ----------------------------------- | --------------------------------------------------------------------------- | ------------------------------------------- | | Disaggregated AI engagement metrics | Separate impressions, clicks and CTR for Search Content used in AI features | By 3 December 2026 | | Controls over AI use | Options to opt content out of AI training or grounding | Page-level controls roughly by March 2027 | | Compliance reporting | Updates on Google's implementation of the requirements | At least every six months in the first year | ## Why separate AI data changes the measurement conversation An AI Overview impression is not equivalent to a website visit. A user may find enough information in an AI-generated response to end their search, or they may choose one of the cited links. Without separate click data, publishers cannot reliably quantify the difference between appearing in an AI answer and receiving referral traffic from it. The CMA's requirement addresses that measurement gap for affected publishers. It should allow teams to calculate AI-feature CTR and compare it with their organic Search CTR, provided Google implements the data in a sufficiently usable form. That comparison will still need care. A lower CTR from AI features would not, by itself, establish that AI results reduced total clicks. Query mix, ranking changes, seasonality, devices and changes to the Search results page can all affect performance. Equally, high AI impressions may indicate prominent use of a publisher's content without demonstrating conversions, subscriptions or revenue. The requirement is a transparency measure, not a guarantee of traffic. It also does not establish that data from the UK implementation will necessarily be offered in the same way to publishers elsewhere. ## How publishers can prepare before reporting arrives The deadline gives publishers time to strengthen their measurement baseline. The most useful preparation is not to guess at AI clicks, but to document existing performance so future data can be interpreted in context. Start by [preserving regular Search Console exports for priority pages and query groups](https://blog.geosearchleads.com/n8n-node-automated-geo-scans-reports-ai-search/). Record impressions, clicks, CTR and average position, along with major content releases, technical changes and seasonality. This creates a pre-implementation reference point for later comparison. Next, identify content that is especially likely to answer user questions directly, such as explainers, product guidance, reference pages and frequently updated editorial resources. These are sensible pages to monitor, but their likely presence in an AI feature should not be confused with confirmed inclusion or attribution. Publishers should also clarify internal ownership. Editorial, SEO, analytics, product and legal teams may each have a role in evaluating AI visibility, referral traffic and the use of new content controls. The future page-level controls could create trade-offs between exposure in AI experiences and restrictions on training or grounding. The CMA requirement confirms that controls must be offered, but publishers will need to [assess their own content and business priorities before using them](https://blog.geosearchleads.com/e-e-a-t-score-website-trust-signals/). Finally, define the questions the new data should answer: Which sections receive AI-feature impressions? Does AI-feature CTR differ by content type? Are clicks growing alongside impressions? What happens to organic performance for the same pages? A measurement plan built around these questions will be more useful than a single AI visibility total. For teams preparing to [evaluate how accessible their content is to AI-driven discovery](https://blog.geosearchleads.com/run-geo-scans-in-chatgpt-mcp-connection/), GEO Search Leads can help frame the technical and content questions worth investigating before new reporting arrives. It is not a substitute for Google's future engagement data, but it can support a more structured readiness review.

The data must be disaggregated by publisher and separated from organic Search data when publisher content is used in AI features. **Will the data be available in Google Search Console?** The CMA states that the information may be made accessible through a platform such as Google Search Console. The supplied requirement does not establish the final reporting interface or layout. **Do the requirements apply only to AI Overviews?** No. The CMA's focus includes AI-driven Google Search features, including AI Overviews and AI Mode. **Do AI impressions prove that a publisher received traffic?** No. An impression shows that content was used or shown in the relevant AI search context. Click data is needed to determine whether users visited the publisher's site, while conversions require separate analysis. --- ## Conclusion The CMA's publisher requirement creates a defined path toward clearer measurement of AI-driven Google Search engagement in the UK. Until Google implements the required reporting, publishers should treat AI visibility and AI referral traffic as separate questions, preserve a strong organic baseline and prepare to evaluate the new data with appropriate context.
