I'm a relative Adwords noob so please bear with me...
I have a small set of adgroups with identical keywords (2 phrases) for a very niche business. Each adgroup represents a different style of advert (e.g. interrogative, imperative...). Budget is capped daily. My aim is to compare and find out which styles work best. My question, which may be stupid, is, are my adgroups competing in any way with each other if they are using the same keyword phrases? Does my default/specified CPC for each adgroup/keyword affect how Google choses which ads to show from within my campaign? I'm confused so I just need to clarify this.
Thanks in advance.
