Abstract: Systems and techniques for a member activity based profile viewing evaluation system are described herein. In an example, a profile viewing evaluation system is adapted to receive a viewed profile event indicating a member profile was accessed by a viewer, wherein the viewed profile event includes a member identification associated the member profile and a viewer identification associated with the viewer. The profile viewing evaluation system may obtain activity data related to activities performed by the member on the online service. The profile viewing evaluation system may obtain attributes of the viewer. The profile viewing evaluation system may determine the viewer is a notable viewer by comparing the attributes of the viewer to the activity data of the member. The profile viewing evaluation system may generate a graphical user interface to display viewer identification information associated with viewers of the member profile, including viewers classified as notable viewers.
