Just food for thought...

Someone I know claims he looks for product launches with names that have potential common typos in their names. He buys the mispelling version of the domain and redirects it to his affiliate link.

Claims just this technique alone has had him profiting $25k this past year.

That all said... this was from a random conversation we had 2 months ago, I didn't validate any of the info and don't have any other details.

Common sense does follow (as domainers run this gimmick tactic too with big success). But just figured I'd post it here as yet another angle to experiment with.
