knowsAbout

knowsAbout is a schema property that explicitly declares a brand, organization, or author's areas of expertise or topical focus, giving AI systems a direct signal for topical relevance rather than requiring them to infer it purely from a site's published content.

Why it matters

knowsAbout is a small, underused implementation that reinforces topical authority in a machine-readable way, particularly useful for a newer site that hasn't yet built the content volume needed for topical authority to be obvious from crawling alone.

Related terms

• Schema Markup / Structured Data

  Schema markup, or structured data, is machine-readable metadata embedded in a page, most commonly as JSON-LD, that explicitly tells crawlers what the content actually is: an article, an organization, a product, a set of questions and answers, rather than leaving that classification to inference.

• Topical Authority

  Topical authority is how comprehensively a site covers a subject area, measured across content depth, breadth, and internal linking between related pages, rather than any single page's individual quality, making it a property of a site's overall content structure.

• Entity Salience

  Entity salience is a score, typically between 0 and 1, indicating how prominent or central a given entity is within a piece of text, a concept borrowed from natural-language-processing tools like Google's Cloud Natural Language API.
