I'm not sure that the url displayed on the ads is necessarily the landing page, so you have to do the above (or use the preview tool) to check out the landing page.
But copying the target URL and pasting into the browser's location bar will register as a click - a fraudulent click at that because it won't show a referring page. If you're interested in seeing who's advertising on your site, just use the partial URL beneath each ad and type it into the location box.
I do make sure that i remove Google's tracking codes.
