Obviously share=unlock is great thing cause we get a backlink. But what about link rot? links we acquire and then we lose them means the platform admin removed them, that they were illegal, or leading to scam. and is very neggative seo People will use share to unlock, then download the file and delete the link from facebook. Facebook posts are probably getting indexed quickly (same as bhw threads) Is the link rot something i should care about or maybe facebook posts dont even index? What you think?
