Google Discover Eligibility Checker

Google Discover is one of the most unpredictable traffic sources on the web. Sometimes a page gets picked up and drives thousands of visitors, and other times similar content never shows up at all.

There’s no official checklist for qualifying, but most pages that appear in Discover tend to share a few common signals: large images, structured data, author information, and mobile-friendly markup.

This tool scans a page and looks for many of those signals. It’s not a guarantee that a page will appear in Discover, but it can quickly show whether the technical pieces are in place.

What the checker looks for

• Headline length
• OpenGraph image and image size
• Image aspect ratio
• max-image-preview settings
• Author metadata
• Mobile viewport tag
• Article structured data
• Publish date metadata
• Publisher schema
• Canonical tag
• HTTPS usage

You can analyze up to 10 URLs at once. The tool generates a simple Discover score and lists any signals that may be missing.

If something is missing, the checker also shows example snippets that can be added to a page to fix it.

Example use

Paste one or more article URLs into the analyzer and run the scan. The results will show which Discover signals are present and which ones might need improvement.

This can be useful when auditing blog posts, troubleshooting low Discover traffic, or checking whether a CMS is outputting the expected metadata.
