Do You Have Duplicate Content?

For my particular niche, and I want to talk about duplicate content, I have posts in clusters where it's a troubleshooting thing. And the words within them are 80% or more exactly the same. The key part is going through that in depth. So when you find a word that looks like it has high volume, checking it across multiple of these tools just to confirm,. Then digging in deep on that first page to see if you have a shot at ranking for it.
