Has anyone seen a set of adwords that when clicked the link opens in a new window?

Im sick of the add stealing my customers who are half way through buying from me, I want it so that if they like the sound of the link

If you don't want visitors leaving your site, remove your Google Adsense ads.

have the addwords on the site because since putting them on it has increased the frequency of the visits from googlebot.

I know everyone says they are not connected, but I built an analytics module for my site, and I can see every single visit from every single bot and scraper that visits my site, and I dont know why the visits increase or if it will increase my serp / rank etc but I only put it on the pages most important to me, and I would feel better if I could leave them on and have them pop up in a new window
