There are different relationships between data when it comes to organizing databases. It starts with Dimensions, which are ways of analyzing data of interest to a business. Dimensions are described by attributes, which can have three different types of relationships.
The first type of relationship is one-to-one, in which each side of the relationship can have only one match. There is also one-to-many, where one party can have multiple matches, but the other side of the relationship can only have one match. The last classification is many-to-many, in which both sides of the relationship can have multiple matches. Hierarchies should only have “one-to-many” relationships to make sure they are accurate.
A Google Ads account can have up to 10,000 campaigns, while each campaign can have 20,000 ad groups, and each ad group can have up to 50 text ads. Applying the hierarchies between attributes to Google Ads can help you understand the structure of your account.
One-to-many is the way to go with your Google Ads account to guarantee efficiency. If you have more than one client or account to manage, create a Google Ads Manager account instead of using a one-to-one relationship to different clients. With Ads Manager, you can have a one-to-many structure, centralizing the up to 20 different accounts in one login.
Keep in mind that Google Ads is organized on three levels of attributes: account, campaigns, and ad groups. Each client can have only one account, but different campaigns with independent budgets and settings. Each campaign can have separate ad groups, with different ads and keywords each.
Best practices say that you should divide different themes into different ad groups. To do it efficiently, keep the one-to-many relationship in mind. For instance, if you sell desserts in your website, create separate ad groups for cupcakes, pies, and cookies, instead of using a broader classification (for instance, flavors) that can make your ads redundant.
