Google Discover has long been a valuable and unpredictable traffic source for publishers: no query, no keyword, just a feed of articles chosen around each user's interests. Since July 2025, some of those cards have looked different. Instead of a single article, the user sees an AI-generated summary of a trending story, with a row of publisher logos and a "see more" link listing the articles it drew on.
For publishers, that raises three practical questions: how often do these summaries appear, how is my site credited, and how do I measure the effect? Until mid-2026 the honest answer to the last question was "you can't, directly". Search Console now has a dedicated generative AI report for Discover, which changes how you can monitor it.
This guide covers what Google has launched in Discover, what has been reported but not officially documented, how sources are credited, and a step-by-step way to monitor the impact in Search Console in 2026.
Key Takeaways
- Google launched AI-generated summary cards in Discover in the US in July 2025, starting with trending lifestyle topics such as sports and entertainment, according to press reports quoting a Google spokesperson.
- Cards show publisher logos, label the summary as AI-generated, and let users expand a list of all contributing articles.
- Search Console's Generative AI performance report (Discover) shows impressions of links to your site inside Discover AI features; Google says it had reached all websites worldwide by 31 August 2026.
- The report shows impressions only, not clicks, so you need to pair it with the standard Discover report and your analytics.
- Further Discover AI formats, such as AI topic overviews, have been reported in tests but are not documented by Google, so treat them with caution.
What Google has launched in Discover
In July 2025, Engadget and Tom's Guide reported that Google had started showing AI-generated summaries in the Discover feed of the Google app in the US. A Google spokesperson described it to Engadget as a US launch of a new feature rather than a test. The summaries focused first on trending lifestyle topics such as sports and entertainment. Each card carries a warning that it is generated with AI and "can make mistakes".
Google's own Discover documentation for site owners does not describe these AI features, so most of what we know comes from reporting and from the new Search Console report. In September 2026 trade press also reported a limited test of AI "topic overviews" in Discover, starting with video-first topics and reached through a "Dive deeper" option, with source links in a carousel below the summary. Google had not published documentation of that test when we checked, so we treat it as reported, not confirmed. We could not find official Google documentation for a Discover feature called "trending previews", so we do not describe one here.
How sources are credited
| Element | What users see | What it means for publishers |
|---|---|---|
| Publisher logos | Logos of the news sites in the corner of the card | Brand exposure even without a click; a strong logo and site name matter |
| AI summary | Short generated text summarising the story | Users may get the gist without visiting any source |
| "See more" list | All articles that contributed to the summary | Your link competes with several other publishers on the same story |
| AI label | "Generated with AI, which can make mistakes" | Errors are attributed to Google's summary, not your article, but your logo sits next to it |
Because several publishers share one card, the summary favours stories with broad coverage. Distinctive reporting, analysis and first-hand content that others have not covered is less likely to be folded into a shared summary, and remains eligible to appear as a standard Discover card.
How Search Console measures Discover AI features
Search Console now has two generative AI reports: one for Search (AI Overviews and AI Mode) and one for Discover. The Discover version defines its metric clearly:
“Impressions are how many links to your site that a user saw in generative AI features in Discover.”
— Search Console Help, Generative AI performance report (Discover)
| Report detail | What Google says | Practical note |
|---|---|---|
| Metric | Impressions only | No clicks or CTR in this report |
| Counting | A link must scroll into view; one impression per result per session | Scrolling back does not double-count |
| Pages | Grouped by canonical URL of the source page | Check canonicals if pages seem missing |
| Other dimensions | Countries and dates (day, week, month, Pacific Time) | No device breakdown for Discover |
| Availability | Rolled out over time; reached all websites worldwide as of 31 Aug 2026 | Needs enough impressions to show |
| Limits | 1,000-row table limit; Search Labs data excluded; "~" or "-" export as zeros | Export regularly to build history |

A step-by-step monitoring routine
- Open both reports. In Search Console, compare the Generative AI performance report (Discover) with the standard Performance report filtered to Discover.
- Find AI-exposed pages. Export the Pages table from the generative AI report to see which articles were linked inside AI features.
- Match them to Discover clicks. Join the export with the standard Discover report by URL. Pages with high AI impressions but falling Discover clicks are the ones to watch.
- Segment by topic. Tag URLs by section (sport, entertainment, news, evergreen) to see where AI features appear most.
- Add annotations. Mark Discover-related announcements and core updates, so you do not blame AI summaries for an update. Our guide to Discover traffic drops after updates helps separate the two.
- Build a dashboard. Export weekly, because the reports have row limits; our AI search dashboard in Looker Studio guide shows one way to keep history.
- Review monthly. Look for trends over several weeks; Google warns that Discover traffic is naturally less predictable than search traffic.
What publishers can do
- Follow the Discover basics. Google still recommends timely, well-told content with unique insight, accurate headlines without clickbait, and large images at least 1,200 pixels wide with
max-image-preview:large. See our Google Discover guide. - Strengthen your brand mark. If users see your logo in a shared card, recognition is your main benefit. Keep logos and site names consistent.
- Prioritise distinctive coverage. Exclusive reporting, analysis and expert commentary stand out from shared summaries.
- Decide on preview controls deliberately. Controls such as
nosnippetandmax-snippetlimit how content is used in Google's AI features, but also affect normal snippets. Our guide to AI snippet controls covers the trade-offs. - Plan for zero-click value. Consider newsletter sign-ups and follow buttons that turn brand exposure into a direct relationship; our guide on AI search for publishers covers more options.
Common mistakes
- Reading impressions as traffic. The Discover AI report has no clicks. Always pair it with the standard Discover report.
- Blaming every drop on AI summaries. Discover traffic moves with user interests and updates too.
- Acting on unconfirmed features. Tests reported in the press may never launch widely. Wait for Google documentation before major changes.
- Clickbait headlines to "beat" the summary. Google's Discover guidance explicitly warns against misleading or exaggerated titles.
- Ignoring canonicals. The report groups by canonical URL; syndicated or duplicated articles may be credited elsewhere.

Frequently Asked Questions
What are AI summaries in Google Discover?
They are AI-generated cards in the Discover feed that summarise a trending story from several publishers, showing publisher logos and a list of the contributing articles. Google launched them in the US in July 2025.
Can I see Discover AI summary traffic in Search Console?
You can see impressions. The Generative AI performance report (Discover) counts how many links to your site users saw in Discover AI features. It does not report clicks, so compare it with the standard Discover report.
Is the Discover AI report available for all sites?
Google says the report had reached all websites worldwide as of 31 August 2026, but a site needs enough generative AI impressions in Discover for the report to show data.
Can I opt out of Discover AI summaries?
Google has not documented a Discover-specific opt-out. Preview controls such as nosnippet limit use of your content in AI features but also affect regular snippets, so test carefully.
Do AI summaries replace normal Discover cards?
No. They appear for some trending topics alongside standard article cards. Google's Discover documentation for site owners still applies to regular cards.
Conclusion
AI summaries change what a Discover impression is worth, and Search Console finally lets you see how often your links appear inside them.
