How domain targeting works

There are flexible options when setting up domain targeting. In general, you can target top-level domain names and subdomains, but you cannot target domains that include path-level sub-directories, as shown in the following diagram.

When you target domains or exclude domains from being targeted, be sure to be as specific as the targeting requires. The following table explains how domain targeting works for each example provided.

Example	Inclusion targeting	Exclusion targeting
website.com	All of website.com and any subdomains of website.com would be targeted in the deal A private auction that allows publishers to offer specific inventory directly to selected buyers identified by a deal ID. Terms are negotiated and are agreed upon before the auction occurs.. For example, blog.website.com and support.blog.website.com would be targeted in the deal.	All of website.com and any subdomains of website.com would be excluded from being targeted in the deal. For example, blog.website.com and support.blog.website.com would be excluded from targeting.
blog.website.com	Only blog.website.com and any lower-level subdomains of blog.website.com would be targeted in the deal. For example, support.blog.website.com would also be targeted, but news.website.com would not be targeted.	Only blog.website.com and any lower-level subdomains of blog.website.com would be excluded from being targeted in the deal. For example, support.blog.website.com would be excluded, but news.website.com would not be excluded.
support.blog.website.com	Only support.blog.website.com and any lower-level subdomains of support.blog.website.com would be targeted in the deal. For example, uk.support.blog.website.com would also be targeted, but blog.website.com would not be targeted.	Only support.blog.website.com and any lower-level subdomains of support.blog.website.com would be excluded from targeting. For example, uk.support.blog.website.com would be excluded from targeting, but blog.website.com would not be excluded.
