A WebmasterWorld thread discusses the pros and cons of using Google’s allowed sites feature in AdSense. In short, the Allowed Sites feature is a tool to tell Google, where you want your ads to show. For example, if someone steals your content and takes your ads with your content, they are in a sense, showing your ads. You can specify to Google, I only want my ads to display on specific domains or subdomains.

Google began testing this feature back in June of 2007 and based on popular request they launched it in late August. Google then had several bugs in the tool that worried many publishers.

So what are the pros and cons of using this feature:

Pros:
Control your adsEnsure you don’t get your account disabled because of someone else’s contentCalm your paranoia

Cons:
Bugs can prevent your ads from displaying (rare)You won’t make money on those scraper sitesUsers cant view your ads on translation pagesYou may forget to allow some of your sites

I am sure I missed some items, so feel free to comment.
