A/B Test -> Variation B should not be indexed / robots=noindex

[Dave1st]

Hi,

I´d like to do some A/B-tests in my shop.

I have a variation-A and variation-B (different colors and location of the buttons).

But the content is the same.

Is there any chance to set variation-B.html as noindex?

Or do I have to set the whole shop as noindex, perform my A/B-Test for some weeks and the turn indexing on?

Any idea or a workaround?

Thanks
Dave
