We teach to use subdomains. Please review the training in Part 7 as it's there. The Search Term campaign starts immediately and runs continuously as it has your winning KWs in it. This will lower your overall costs for the KW, campaign and even on the account level. We recommend you run with three versions of the converting KW (broad OR BMM, phrase and exact). All low search volume KWs shown even in the Search Terms campaign MUST be deleted immediately.
