I don’t know about you, but I don’t trust these domain scalpers displaying my ads and telling me someone clicked on it. I do not trust Google either and I do not want to have any of my ad $$ going to anyone of these. They are annoying anyways, as they block all decent domains.
Here is a quick guide how you can prevent your ads showing up on these sites.
First log into your Adwords account. Next click on ‘Reporting and Tools’ tab. On the bottom of the drop down you find ‘more tools’ - perfectly hidden. Google wants the $$. Next click on Site and Category Exclusion Now you are nearly there Click on the tab ‘Page Types’ Now you can choose ‘Parked Domains’ I do exclude error pages as well.
Hope this helps and I hope Google would stop serving ads to them.!!
