Placements: Advertising on non-search websites
Keywords can trigger your ads to appear next to search results on Google and other search sites. But keywords can also trigger your ads to show on other sites across the Internet -- Google-owned properties like YouTube as well as Google's partner sites like NYTimes.com or Families.com, for example. We call these placements, which are part of what we call the Display Network.
Google can automatically determine where your ads appear by matching your keywords to websites in the Display Network. Or, if you'd like greater control over where your ads appear, you can pick specific placements yourself. You can set bids for each and choose the sites where your ads might appear.
