Delete, redirect, or noindex a dead post? Three different calls.

Delete, redirect, or noindex a dead post? Three different calls.
Content audit turns up 80 zombie posts. People nuke them all. Wrong — each needs a different move.
— Has backlinks but no traffic + no fit: 301 it to the nearest relevant page. Keep the equity, lose the dead weight.
— No links, no traffic, topic still matters: don't delete — MERGE it into a stronger post and redirect.
— No links, no traffic, off-brand junk: delete, let it 410. Clean signal to Google.
— Thin but seasonal/legit: noindex, leave it for users.
Tag every audit row with one of those four. Then execute. Don't just hit delete.
