I have general question regarding redirection.
Suppose I have one link which is indexed in Google. Later I changed the URL of that link also to avoid broken link I have used redirection plugin to redirect the old link to new one.
So, Do I need to keep that redirection for lifetime or shall I delete it after some time? Because I have so many redirected links present for my blog, some are useful. I wanted to delete few of them.
Will Google delete my old link from its DB?
