Niche Blogging success Not updated

Im going through the niche blogging success course and you mentioned that keyword research is the most important step of that course. The keyword planner that you are using in that course I believe is the old version, it is not updated to the keyword planner that is current. So i think their are a few differences, one of which being I have to sign up and create an account and link a debit or credit card up, and above all the research tool is a little different along with a few other things. I don’t see search results (below 2mil), but I do see monthly search results (above 10). Im addressing this because you mentioned its very important that we get this right if we want to be successful with niche blogging. So is their something i’m doing wrong?
