If you're advertising on Google's search or content networks, your ads may be appearing on parked domains. Parked domains are sites using AdSense for Domains, which allows domain registrars to show relevant ads, rather than empty space, on parked pages. But which parked domains did your ads appear on?

We recently added a new level of detail to Placement Performance reports to answer this question. Placement Performance reports give site-by-site performance metrics for the sites where your ads appeared within Google’s content network. Now, rather than seeing one consolidated entry for all parked domains in your reports, you'll see separate rows displaying performance statistics for individual parked domains. Select the 'Special Category' column when creating a report to identify whether a site where your ads appeared is a parked domain.

Showing ads on parked domain sites can be very effective. For example, Garden State Life Insurance receives 60 percent of their sales on the content network from parked domains:

"Ads that appear on parked domain pages produce very qualified traffic, and that traffic converts on our website in a similar manner to our search network traffic."

-Michael Musselman, Garden State Life Insurance
