This document outlines a PhD workshop presentation on extending the homophily theory to human images on hotel websites. The presentation aims to study how customers respond to similar-other images on hotel websites and determine the most effective way to design such images. It proposes experiments to test whether demographic and behavioral similarity elicited by images leads to more positive cognition, affect, and booking behaviors. The expected outcomes are insights for customizing human images on websites to increase purchase behaviors among target customer segments.
