...As I was doing so, an idea entered my head. Monetizing your "404 error" page, which surfaces any time someone enters an incorrect link to somewhere on your domain.
Surely if you've got a loyal ever-returning audience and a high traffic volume, you're leaving money on the table by not monetizing this page.
Firstly, how would I go about redirecting all non-existent and misspelled link entries to one specific 404 page?
Also, I thought about placing a squeeze page on this 404 page, with a pre-headline along the lines of "Oops! This Page Doesn't Exist But Don't Leave Empty Handed. Download The FREE (whatever the lead magnet is) below...", leading into the headline with an opt-in box below it...
I'd like to hear other ideas of how people would choose to leverage this page.
