Is it fair to say, given the sufficient resources to manage the account. The ideal setup would be say 100 keywords in 100 different ad groups? Then, in each ad group, you have keywords separated out to broad, phrase and exact match. Then, you have multiple ads that you are testing?
I realize that we all have limited resources, but given the time would you do best with Google to have a 1:1 ratio?
Is there a limit to how many ad groups you can have?
Just trying to understand adwords optimization a little bit.
