One way of reaching new audiences is using a
similar_user_list. With this user list you can target
people who share characteristics with those in your other user lists.
A similar_user_list is
automatically generated by Google for each UserList,
based on a variety of factors; for example, the number of people on the original
list, how recently they joined the list, the types of sites they browsed, and
whether the list is yours. This process may take up to four days starting from
when the source list was created.
The search query demonstrates how to find all available
similar_user_list
objects given a seed user list.
String searchQuery = "SELECT user_list.id, user_list.name " +
"FROM user_list " +
"WHERE user_list.similar_user_list.seed_user_list = '" + seedListResourceName + "'";
