Suggestion for google ads for visitors
You should probably edit the anchor tag, for these links/ads, to something like this :
<A HREF..blah blah blah.. [B]TARGET="_blank"[/B]>The last part i.e. TARGET="_blank" will open the links in a new tab/window.
The reason I pointed this out is because, I think it would be a better idea to keep the crazyengineers web page open while the visitor is looking through the other site, rather than opening the ad in the same page. This way (opening the ad in the same page) the visitor navigates away from CE and may loose interest.
While keeping the page open in the background does not gurantee that the visitor will return to CE, but it gives us a fighting chance!!
