I have a .pdf file hosted in File/Image section of Marketo, back from 2012. One of our prospects somehow found this file link by rigorously searching on google, and now my team wants to take it down.
I'm afraid of deleting the file to avoid the negative impact on SEO, while we don't have a replacement file as this pdf is about the product we no longer offer.
I contacted the support and they confirmed that we cannot redirect the file URLs.
Does anyone have any idea if this file link will be marked as 410 Content Deleted or 404 Not Found? The former seems better than the latter from the SEO perspective.
I appreciate your help as always!
