If we run a business, whether online or offline, in the process we collect data from our customers, as well as information about their needs and the products or services they are looking for. Based on this knowledge, we can create customer lists. This helps reach current customers and re-engage with them in search network campaigns, Google Shopping campaigns, Gmail, YouTube, and display campaigns.
To effectively utilize this feature, you should start by creating a file with selected customer data (following the provided guidelines – creating a customer list) and add it to your Google Ads account. In customer lists, you can use data such as: first name, last name, email address, phone number, and postal code. Not all data needs to be used; you can focus on one guideline, such as phone number or email address. Additionally, the list doesn’t have to consist only of data from people who have purchased our products or used our services. It can also include individuals who have provided their contact information (email address, phone number), for example, by signing up for a newsletter.
To upload such a list, you need to take the following steps:
Tools & Settings > Shared Library > Audience Manager > Segments > White plus on a blue background > Customer list > Next, manually upload the prepared file or connect the data source using a CRM platform.

When our Google account already contains customer data lists, we can create (or update) a campaign in which we want to use them. In the audience section, we select this specific list. When our customers, whose data we have used to create the list, log in to their Google accounts, they will be able to see our ads.
Google Display Network: At least 100 active users in the last 30 days. Search Network, YouTube, Discovery: At least 1000 active users in the last 30 days.
The data files we send to Google will be used solely for the proper functioning of the campaigns; all information will remain confidential. This happens because Google converts all the data it receives into encrypted codes.

By having the ability to create audience lists with data from our existing customers, we’ll be able to introduce new products/services offered by our company to them more quickly. There’s a likelihood that among these users, we’ll be able to achieve the highest conversions.
Customer list targeting serves as a tool for managing audiences that does not collect data about website users using traditional tags. All data is secure and encrypted by Google.
