A knowledge panel is a prominent information box that appears on the right-hand side of the search engine results page (SERP) when a user searches for a specific entity, such as a person, organization, or landmark. It provides a concise summary of key details about the entity, including a brief description, images, related links, and additional information sourced from reputable websites. The knowledge panel aims to provide users with quick and comprehensive information without requiring them to click on any search results.
