What is the difference between a campaign and an ad group in Google Ads?

In Google Ads, understanding the hierarchy and relationship between campaigns and ad groups is crucial for setting up effective advertising strategies. A campaign is designed to encompass one or more ad groups, which allows advertisers to organize their ads based on a common objective, such as reaching a specific target audience or promoting a particular product or service.

The structure where a campaign serves as a container for multiple ad groups enables advertisers to manage budgets, settings, and overall performance at the campaign level while honing in on specific messaging and targeting within each ad group. This layered approach simplifies the organization of ads and facilitates a more strategic alignment with business goals.

By grouping ad creative and keywords into ad groups, advertisers can tailor their content to better match user intents and increase relevance, ultimately enhancing the effectiveness of their campaigns. This structure of having multiple ad groups under one campaign is fundamental to maximizing the potential for successful ad performance across different segments of a marketing strategy.
