Backlink 404 expired domain

Hello i never did that, but i wonder if i need to.

All backlink from my expired domain who are going to anyother page than main page, are 404.

I believe if it's hurt SEO, i'm pretty sure no traffic coming from thoses backlink.

I wonder how you handle see, it's hurt for my metrics ? Do i need to make a new page with the exact same url if the backlink is good ? Do i need to 301 to an another page ?

How do you handle this Thanks !

Simply look at the top pages in majestic, ahrefs or moz and 301 redirect any that have existing backlinks to the homepage. There's really nothing else to it.
