A/B Testing and NoIndex, NoFollow

[J-Spider]

When running A/B testing in AdWords is it important to use "NoIndex, NoFollow" meta tags if the 2 pages you are using have very similar content? Thoughts?

And this also applies to PPC landing pages in general - Is it a good idea to "NoIndex, NoFollow" in general?

Thanks for your feedback,

I have often wondered the same thing. I am assuming If google can not read content on your page(s) then would you not have a lower quality score which would drop the position of your ad? Since your ad would drop wouldn't you recieve less clicks and false information when testing pages?

Well are you using Google Website Optimizer? They will bucket test the traffic for you as far as I know.
