Before I comment, I'd like to clarify a few things in my own mind, so I make sure I am commenting correctly.
1. Did you get these numbers (SEOT, PBR, SEOC and Matrix) from an All Countries & Territories search? Or something else?
2. Do you have the Google Global Plugin installed on Chrome? (I'm thinking yes, I just want to check).
For your category keywords you are thinking of running with - did you run a new keyword analysis with your proposed Theme Keyword as the next master keyword?
Thanks in advance for your responses. And do not worry about falling behind. This is an 'off week' so you have plenty of time to get up to where we are at in the Training - every second week you have that opportunity
