Relationship between Campaign->AdGroup->keyword

Adwords are so intricate

[genem]

Hi,
My first major finding from this forum is the fact that adwords is a rather complex system, not just your regular advertising vehicle.

Now, before I ruin my 2 month old campaign, can anyone please elaborate on the gotchas of the Campaign->AdGroup->keyword relationship?

I understan how the individual kw performance (CTR) is improtant, but how important is the performance of the AdGroup? Should I manipulate the kw list to improve the AdGroup ctr? Is the performance of th Campaign important too?

Thanks, guys.

I just asked a similar question on a different forum a couple of days ago. :) The consensus was that CTR is looked at on a per-keyword basis so which Ad Groups your keywords were in would not have an impact on Quality Score (which is what's important here). If I'm wrong about this please let me know!

Hi jbischke,
What is QS relevant to?

Where is your original thread?;-)
