I see you can create more than one ad in a keyword group. I was creating a single ad per keyword group, so i could measure the keyword themes that worked best. ex: keyword group 1 (Blue Widgets) [ad 1], [ad 2], [ad 3] keyword group 2 (Buy Blue Widgets) [ad 1] If a someone searches for a KW that is in the (Blue Widgets) Group, which ad will be displayed? I'm pretty OCD about tracking each variable of a campaign.
