Does a website need special markup to qualify for Google Discover?

Definition: Google's interest-based feed can consider a page automatically when Google has indexed it and it meets the feed's content policies. Google says no special tags or structured data are required for this eligibility, and eligibility and appearance are separate outcomes.

Key facts

• Google's eligibility guidance says that indexed content meeting the feed's content policies is automatically eligible, with no special tags or structured data required.
• Google's indexing guide says Google automatically looks for sites to add to its index and that posting a site on the web is usually the only action needed to start.
• Google's indexing guide documents the site:example.com search as a way to check whether pages are indexed, while warning that this operator does not necessarily return every indexed URL.
• Google's spam policy documentation says eligible web search content should follow Google's overall policies and the listed spam policies.
• Google says policy-violating practices can be detected by automated systems or human review and can result in a manual action.

What does automatic eligibility mean?

As of 9 March 2026, Google's eligibility guidance defines the condition with two checks: Google has indexed the content, and the content meets the feed's content policies. The same guidance separates eligibility from appearance. It also says that older content may appear when it is helpful and relevant to a person's interests, so older content remains within the documented scope.

The indexing check belongs to Google's normal web process. The indexing guide, updated 10 December 2025, says Google automatically looks for sites to add to its index and usually needs no action beyond putting the site on the web. It also lists missed crawls, a new site awaiting its first crawl, difficult-to-crawl design, and crawl errors as reasons a site might be absent from the index.

Does structured data change this eligibility?

No special tag or structured data type is required for the eligibility condition. Google separately recommends schema.org markup or the og:image meta tag to specify a large, relevant image, because this can influence which image is chosen as the thumbnail in the feed. That recommendation concerns image selection rather than the basic indexed-and-policy-compliant condition.

Google also lists image settings for large previews. Its page recommends images at least 1200 px wide, with more than 300,000 total pixels and a 16x9 aspect ratio. It lists this setting as one way to enable the large preview:

max-image-preview:large

These image recommendations affect presentation while the indexed-and-policy-compliant condition governs eligibility.

How can a site owner check the two prerequisites?

The first check is whether Google has indexed the page. Google's indexing guide gives this example:

site:example.com

The guide qualifies the site: operator: it can omit indexed URLs under the specified prefix. A missing result therefore needs a separate indexing investigation. The same guide says a new site can take a few weeks for Google to notice, and that a login page or another block can cause a crawl error.

The second check is policy compliance. The spam policy page, updated 28 August 2026, says that policy violations can cause content to rank lower or be absent from results. It also says that continuing to bypass spam or content policies can lead Google to restrict or remove eligibility for search features, including the feed covered here. The Discover documentation says a policy violation can produce a manual action in Search Console under Security and Manual actions.

FAQ

Does JSON-LD make my page eligible?

No. Google says special tags and structured data are not required for eligibility. You can use schema.org markup or og:image to suggest a relevant thumbnail image, which is a separate presentation question.

Does indexing make appearance automatic?

No. Google separates eligibility from appearance. The page still needs to match the feed's content policies and the interests that guide what people see.

How can I check whether my page is indexed?

You can search for your site with site:example.com, as Google's indexing guide shows. Google qualifies this operator because it can omit indexed URLs.
