# Google Discover

> Indexed content that meets Discover's content policies is automatically eligible for Discover, with no special markup, though eligibility is no guarantee. Google recommends large images at least 1200px wide and titles without clickbait. Discover traffic is less predictable than search traffic and should be treated as supplemental.

## Images

> **Officially documented:**
> Google recommends large, relevant images: "At least 1200 px wide", more than 300,000 total pixels and a 16x9 aspect ratio. They should be enabled by the max-image-preview:large setting. Specify the image with schema.org markup or `og:image`. Avoid generic images there, such as your site logo, and text-heavy images.

## Traffic changes

## This site

Indexable pages here set `max-image-preview:large`. Each entry has its own share image showing its title, type and evidence level, rather than one site-wide image. The images are 1200×630, the common Open Graph size. That is about 1.91:1, not the 16:9 Google recommends for Discover.
