The Components of a Google AdWords Campaign
A campaign is part of the Google AdWords account that has its own budget, location and language targeting and network targeting preferences. Google AdWords campaigns can also have one or more ad groups, with each one containing at least one ad to go with keywords or related placements.
Through network targeting, you can have your ads on Google search, search partner sites and the Google Content Network. On the Content Network, you can choose between running your ads on specific and relevant pages across the entire network or only have them on relevant pages just on the placements you’re managing.
