Audit summary
Per-tag results
Start here · What are meta tags?
Meta tags are pieces of HTML in a page's head section. They describe the page to browsers, search engines, and social platforms.
Common examples include title, meta description, robots directives, canonical tags, Open Graph tags, and Twitter card tags.
A meta tag audit helps you find missing, duplicate, conflicting, or overly long fields before they affect search results or social shares.
