2 URLS pointing to the same content

[Party_Experts]

Hi,

We currently have 2 URL's pointing to the same website (long story why we have it) - A & B.  A is our main website but we set up B as a rewrite URL to use for our Pay Per Click campaign.  Now because its the same site, but B is just a URL rewrite, Google Webmaster Tools is seeing that we have thousands of links coming in from site B to site A.  I want to tell Google to ignore site B url but worried it might affect site A.

I can't add a no follow link on site B as its the same content so will also be applicable on Site A.  I'm also worried about using Google Disavow as it might impact on site A!

Can anyone make any suggestions on what to do, as I would like to hear from anyone with experience with this or can recommend a safe option.

Thanks for your time!

Use rel=canonical tag that shows A is the canonical version.  Here's more on how to do that:
