301 redirect is necessary??

[nickdime]

I am rebuilding my blog. There are some pages which have no links towards them and also they are not getting any traffic. Should I delete them or 301 redirect them to new pages? What's your opinion.

Deleting them is not necessary redirect them through 301. It better then user's getting 404 error or those pages.

You should check their link base first, I mean each of the urls then decide something.

Is these kind of plugin is useful for any websites?
