Until now I'd been told that duplicate content was something to be avoided like the plague. When it comes to article marketing, I've always tried to create unique content, ultimately the information might not change very much but I never copy and paste content when writing my articles.
Obviously this is very time intensive and I'm wondering:
- What tools you use to spin articles
- How useful these tools are
- How much duplicate content you can get away with when publishing articles to different dofollow article directories.
