My question is; is this conversion data kept if the keyword gets deleted in one adgroup and added to another (which is what happens) or do all conversion counters go to zero for these keywords?
Here's the scoop:
The deleted keyword will only retain stats in the way that all deleted keywords retain stats.
By this I mean, if you view all deleted items from the original ad group for a time period during which those keywords existed and had conversion tracking enabled, you will see those past stats.
However, those stats will not move to the new Ad Group.
NOTE: this may be a good time to mention that for the next four days I'll be spending a great deal of time at the infamous "House with No Computer" (otherwise known as Mom's house).
This means that after today, I'll be posting minimally - if at all - until Monday the 30th. I'll try to check in, if possible.
Just a heads up. ;)

I figured something like that (from a programming perspective :-). Still, moving keywords around more freely would be on my shortlist for next versions of adwords.
Enjoy turkey day! (we skip that in Europe)
BTW, the keyword optimzer works like a charm now, it just takes some patience (something which always is in short supply with me :-)
