Metadata is data that describes other data — in a web context, information about a page that isn't part of its visible content but helps search engines, browsers, and other systems understand what that page actually is.

  • Title tags — the clickable headline shown in search results
  • Meta descriptions — the short summary shown beneath a title in search results
  • Open Graph tags — control how a link appears when shared on social media
  • Schema markup — structured data describing specific content types in detail
  • Image metadata — alt text and file information attached to images
  • Directly shapes how a page appears in both search results and social media shares
  • Helps search engines correctly understand and categorize a page's content
  • Improves accessibility, particularly through descriptive image alt text
  • Can meaningfully affect click-through rates from search

SEO plugins like Yoast or Rank Math give a dedicated, simple interface for managing most page-level metadata, without needing to write or edit any actual HTML directly.
