Metadata
Hidden page information that describes a page to browsers, search engines, and social platforms.
Definition
Metadata includes title tags, meta descriptions, canonical links, robots directives, Open Graph tags, Twitter tags, viewport tags, and other head elements.
Meaning
It controls how pages are understood, indexed, previewed, and displayed outside the page itself.
Why It Matters
Weak metadata can reduce search clarity, social sharing quality, and technical trust even when visible content is strong.
History And Context
HTML metadata has existed since early web standards, but its importance expanded as search engines, social platforms, and mobile browsers used it for richer page interpretation.
