A set of ad groups (ads, keywords, and bids) that share a budget, location targeting, and other settings. Your AdWords account can have one or many ad campaigns running.
- Each campaign consists of one or more ad groups, a budget, language and location settings, distribution settings for the Google Network, and other settings.
- Campaigns are often used to organise categories of products or services that you offer. You can also create separate ad campaigns to run ads in different locations or using different budgets.
