Meta tags placed in the document body are ignored by search engines and most browsers—directives like noindex or canonical-url are silently ineffective, causing pages to be indexed or de-indexed unexpectedly.
Parse the HTML and check whether any <meta> elements appear outside <head>—i.e., inside <body> or after the </head> closing tag. Flag each misplaced tag by name/property.
Move all <meta> tags into the <head> section before </head>. If they are injected by a script after the DOM is built, refactor the injection to target document.head instead of document.body.
Meta tags are document-level metadata and must live in <head>. When placed in <body>, they fall outside the metadata model of the document—search engines and browsers do not honour them, so directives like noindex or canonical-url will have no effect.
Parse the rendered HTML and check the DOM structure. Find all <meta> elements. For each one, traverse up the parent chain — if any ancestor is <body> or if the element appears after </head> in the source, flag it. Pay special attention to: meta name='robots', meta name='description', meta property='og:', and link rel='canonical' placed in body.
