The RLSA Links Manager makes it easy to associate multiple remarketing lists for Search to many ad groups simultaneously in your AdWords account. You can also use it to unlink lists from ad groups. The lists that are added through this optimization can then be bid upon in AdWords.
Currently, the RLSA Linking Manager only works with Search and Shopping campaigns. When you filter by campaign and select a display campaign, you won't see any ad groups.
Our award-winning customer care team is here for you.
