Google Search Console Help · Day 3 · Inside Search Console: What’s New & How to Use It
Slide and stage claims that name it, the ones Google’s documentation does not cover first.
max-image-preview:large matters mainly in Discover, where it allows a large image that draws people's attention, so the rule can make a page more visible than leaving it out, John Mueller said.
John Mueller · Day 2 · Controlling indexing
An image Google has extracted can appear almost anywhere Google shows results, including Discover, image search, web search and AI features, so its potential reach is immense.
Gary Illyes · Day 2 · Using images to your advantage and Engaging Search users with videos
Videos can appear in the main search results, in video-specific result tabs and in Discover (the tab names are unclear in the recording).
Gary Illyes · Day 2 · Using images to your advantage and Engaging Search users with videos
Setting the max-image-preview robots meta tag to large can make content perform surprisingly well in Discover, Gary Illyes said.

Google Discover is not included in Google Trends, because Discover is a content feed with no search box, while Trends counts only the queries people type into Google Search or YouTube.
Omri Weisman · Day 2 · Google Trends
Google's Discover slide showed an eligibility gate: content with a policy violation goes to a policy compliance check and low-quality content to an E-E-A-T quality check, and both can end with the content filtered out, while safe and trusted content becomes eligible for Discover.
Google's Discover slide said that for eligible content image quality decides click-through: a small thumbnail lowers the click-through rate and a large, high-resolution image raises it.
Google's Discover slide said images are subject to the same policy requirements as the content and that misleading, exaggerated or outrageous images should be avoided.
The max-image-preview rule sets the maximum size of a page's image previews: none shows no preview, standard a default-sized one and large the largest possible, for example in Discover.
John Mueller · Day 2 · Controlling indexing
Google's Discover slide defined E-E-A-T: experience means first-hand, personal experience with the topic, expertise the necessary knowledge or skill, and authoritativeness the extent to which the creator or website is known as a go-to source for the topic.
Google's Discover slide said trust comes first: untrustworthy pages have low E-E-A-T however experienced, expert or authoritative they seem.
Google's Discover slide recommended large images at least 1,200 px wide, with more than 300,000 total pixels and a 16x9 aspect ratio, enabled by the max-image-preview:large setting.
Google's Discover slide said to avoid generic images, such as a site logo, and text-heavy images.
The keynote's third driver was that information quality remains a core focus for Google, which wants high-quality sources to serve across Google Search, its AI experiences in Search, YouTube and Discover.
Lino Cattaruzzi · Day 1 · Welcome and opening keynotes
John Mueller speculated that the use of max-video-preview may change in future, for example in Discover, where letting people view a full video could make sense.
John Mueller · Day 2 · Controlling indexing
Google's closing Discover slide pointed to the Discover content policies in Google Search Help and to the Search Central documentation.
Google Trends cannot show demand that reaches people through the Discover feed, so Discover visibility has to be judged from Search Console's Discover performance report rather than from Trends.
Ibrahim Anjro · Day 2 · Google Trends
For Discover, set max-image-preview:large on article templates, give every article a relevant image at least 1,200 px wide in og:image or schema.org markup that is neither the site logo nor text-heavy, and show clear bylines and dates.
Ibrahim Anjro · Day 3 · Uncovering Trustworthy Experiences on Discover
Review the filters and regexes that Search Console's AI-powered configuration proposes before trusting the numbers: Google's launch post calls the feature experimental, warns that AI can misinterpret requests, and limits it to the Search results Performance report (not Discover or News) and to configuration, not sorting or exporting.
Ibrahim Anjro · Day 3 · Inside Search Console: What’s New & How to Use It
Search Console's generative AI performance reports count impressions only, with no clicks and no query dimension (Google documents the Search report for AI Overviews and AI Mode, plus a separate Discover report), so measure visits that follow AI answers with your own analytics.
