Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.
HTML issues tagged as noscript.
A start tag for <img> has been found inside a <noscript> section within the <head>, where it’s not allowed. Consider moving it to the <body> section.
The HTML <noscript> element defines a section of HTML to be inserted if a script type on the page is unsupported or if scripting is currently turned off in the browser.
This issue is often related to 3rd party tracking pixels like the Facebook or LinkedIn conversion tracking pixels. For example, the Facebook pixel instructions tell you to insert it like this:
<html> <head> <script> ...some script... </script> <noscript> <img src="..." /> </noscript> </head> <body> ... </body> </html>
Instead, consider moving the <noscript> part inside the <body>, where the <img> makes sense to be inserted:
<html> <head> <script> ...some script... </script> </head> <body> ... <noscript> <img src="..." /> </noscript> </body> </html>
