This study analyzes how web audiences flow across online digital features. We
construct a directed network of user flows based on sequential user
clickstreams for all popular websites (n=1761), using traffic data obtained
from a panel of a million web users in the United States. We analyze these data
to identify constellations of websites that are frequently browsed together in
temporal sequences, both by similar user groups in different browsing sessions
as well as by disparate users. Our analyses thus render visible previously
hidden online collectives and generate insight into the varied roles that
curatorial infrastructures may play in shaping audience fragmentation on the
web
