How to provide authoritative supporting materials when applying for a Google Knowledge Panel?

When applying for a Google Knowledge Panel, authoritative supporting materials must come from credible, independent, and widely recognized sources to verify the identity and key information of the subject (individual, brand, or organization). Generally, priority should be given to providing official or third-party authoritative content directly related to the subject. Official channels: The "About Us" page of the brand's official website, scanned copies of business registration documents, or official social media verified accounts (with verification badges displayed). Authoritative media: Feature reports or in-depth interviews about the subject from mainstream news websites (such as Reuters, BBC) and industry authoritative publications (such as Forbes). Academic/professional institutions: For academic figures or institutions, introductions on university official websites, papers in academic databases (such as Google Scholar), or certification documents from industry associations can be provided. It is recommended to prioritize organizing the latest materials from the past 1-2 years, ensuring that the content directly relates to the subject's core identity (e.g., founder, brand history), and avoid citing secondary or non-directly relevant information. When submitting, clearly label the source links and publication dates of the materials to improve review efficiency.
