Do my keywords lose ranking if I change ad copy?

I have keywords with very high CTR, will they start over if I try a new ad?

Not sure about this one. I hope this isnt the case.

If i have an ad running, lets say 5% CTR, and I want to get it higher, so I "Create New Ad" and use different ad copy.

Will this keyword lose its rank (which is high b/c of the high CTR)? Does it get reset b/c I add new copy?

Hope someone knows the answer to this.

From what i know Zack, Google will rotate both your ads, and depending upon the effectiveness of your second ad, you may or may not lose your current rank.

But if your second ad gets more clicks than the one you are currently running, you will end up a winner! It all about experimenting! ;)
