Google has launched a new retargeting feature for Google Shopping ads.
Customer Match For Shopping allows advertisers to target high-value users when they search for relevant keywords.
High value customers are people such as previous online buyers, in-store buyers, newsletter subscribers and rewards members.
To target them using Customer Match For Shopping, advertisers need to upload a list of their email addresses into Google AdWords and then increase bids for this segment of customers.
Google can then detect when these users are logged in and show them your Google Shopping ads when they search for relevant terms.
Advertisers can currently sign up for the beta version of Customer Match For Shopping. It will be rolled out fully later this summer.
