I've implemented a no index tag in my staging website header because I've realized it was being indexed. But when we run this page in screaming frog or this tool here to verify the noidex is present and functioning, it shows that it's not.
But if you view the source of the page, the code is present in the head tag. And unfortunately we've seen instances where Google is indexing pages we've noindexed. Any thoughts on the example above or why this is happening in Google?
