I am new at running my adwords campaign. I think I am doing ok. Someone else set the account up for me. I want to make some changes as far as cpc and deciding what is the best position for that word. How do I know when to move a keyword up or down in position? I am afraid to change something and have my ctr go down. If I do make a mistake is there a way to set my account to where it was at a certain date?
You need to check the competition, for your keywords. If I were you, I would copy my AdWords data into Excel or Wordpad, for later reference.
