If you know you’ll be creating duplicate material, the simplest solution is to use a canonical tag. It notifies Google, “I’m aware this website contains duplicate content – here’s where the original is.”

Making a landing page duplicate for a pay-per-click marketing campaign
Using an article written by someone else on your blog
