How the Google Discover Algorithm Works in 2026

Last reviewed . Every claim links to its official source. By Muhammed Abdul Kalam

Any page indexed by Google is automatically eligible for Discover — no special tags are required. Google uses the same helpful-content signals as Search, plus Web and App Activity to match content to personal interests. High-quality images at least 1200px wide significantly improve distribution. Clickbait and sensationalist content is actively filtered.

Google Discover is an interest-based feed on Android and iOS that surfaces content without the user searching for anything. It shares ranking signals with Google Search but weights interest personalisation more heavily. Every claim on this page comes from Google's official Search Central documentation for Discover.

Google Discover algorithm: FAQs

Do you need to apply or add special markup to appear in Google Discover?

No. Google's official documentation states: "Content is automatically eligible to appear in Discover if it is indexed by Google and meets Discover's content policies." and "No special tags or structured data are required."

Does Google Discover use the same signals as Google Search?

Largely yes. Google states Discover "makes use of many of the same signals and systems used by Search to determine what is helpful, people-first content." Interest personalisation is added on top of that base.

Does image size affect Google Discover performance?

Yes significantly. Google's guidance states that large, high-quality images of at least 1200px wide and 16:9 aspect ratio improve Discover performance. Images must be properly specified via schema.org or og:image meta tags.

What types of content does Google Discover filter out?

Discover may not recommend job applications, petitions, forms, code repositories, or satirical content. Clickbait — misleading or exaggerated preview content — and sensationalism tactics are also actively filtered.

Can a site receive a manual action for Discover policy violations?

Yes. Google states that when sites violate Discover content policies, "Discover manual actions may appear in your Search Console under Security and Manual actions."
