using AdWords to advertise on specific website

Can I with AdWords advertise my website on specific website only?

I want my ad to appear only on a specific subdomain in a website (i.e. subdomain.domain.com)

 

Yes, you have to use placement advertising section when setting up campaign.

 

It's a little harder to find. When you create your ad, click "Placement Targeted" ad instead of "Keyword Targeted." Rather than selecting a topic, select a website instead. Your ad will appear on that website.
