This is a very helpful tip on avoiding the hoops Google would put you through to research keywords. Excellent!

UPDATE: After clicking SKIP THE GUIDED STEP, and creating your login if you didn’t have one already, Google will want you to create a campaign. Ignore this and go back to the Google Keyword Planner and log in if necessary. This should take you directly to the Keyword Planner. Good luck!
