Do not direct users to a page with pop-up windows.

Google AdWords does not allow links to landing pages that generate pop-up windows when users enter or leave that landing page. Pop-ups include any window that opens in addition to the original window – regardless of content. While this will meet the standards of GoogleAds, it will also enhance your chances of generating organic web traffic, since search engine spiders will downgrade dynamic pages like pop-ups. Bottom line: keep it simple!
