Welcome to the Q&A Forum

Hello all - we recently made some changes to our Keyword Difficulty tool. Can you both please send examples of the pending keywords you're seeing to help@moz.com? The Help Team will look into this as soon as possible. Thanks!

Out of interest, I have stopped using the tool altogether now. I use SEO cockpit for keyword research. I wish I could still be using Moz, but its just so limited there is not point.

And then it starts working again

The kwd tool was broken overnight, but is in the process of being repaired right now. So sorry about this!
