Ok, a user reported that they clicked an ad and are getting spammed. I want to remove this advertiser from my site. If the URL doesn't display, how do I tell where it goes without clicking the ad. Nevermind, I held the mouse over it and it says leisure-offer.com Thanks
In Firefox, I right click it and go to properties and check the link there as well. It's usually in about the middle of that looong Google URL.
If you use the AdSense preview tool set to your geolocation, you can see the URL and click on the ads in the tool to open the landing page without the advertiser being charged.
