HTML Metadata
Metadata describes an artifact without necessarily becoming part of its main visible content. Search engines, parsers, document processors, and AI ingestion systems may use metadata differently from human readers.
Questions
Frequently asked
What is HTML metadata?
HTML metadata is information in the document head that describes or configures the page, such as descriptions, canonical URLs, and other meta fields.
Is every meta field visible on the page?
No. Most metadata affects browsers, crawlers, sharing systems, or other software rather than appearing as body text.
