Meta Tag
In one line
Meta tag is the umbrella term for the metadata tags that live inside an HTML <head> — including title, description, viewport, robots and Open Graph tags.
Going deeper
Meta tag is the catch-all label for metadata that lives in the <head> rather than the body. The popular one is meta description, but the family also includes robots, viewport, canonical, Open Graph and Twitter card tags.
It helps to separate two roles in practice: SEO meta (controls indexing and search appearance) and share/render meta (drives social cards and mobile rendering). They live in the same place but solve different problems.
A common silent failure: CMS-generated meta drifts from page intent when the generation rules change later. Putting a quarterly audit on the calendar catches most of these regressions before they reach scale.
