Seeding Viral Content The Role of Message and Network Factors YUPING LIU-THOMPKINS Online viral campaigns require a seeding strategy that involves choosing the first- Old Dominion University generation consumers to spread a viral message to. Building on social-capital theory and [email protected] social-network analysis, this research examine key aspects of the seeding strategy by tracking the diffusion of 101 new videos published on YouTube. The results show that the need for a “big-seed” strategy (i.e., using many seed consumers) depends on message quality. Furthermore, one should choose consumers who have strong ties with the advertiser and who also have strong influence on others, rather than simply wider reach. Among seed consumers, they should share a moderate amount of interest overlap instead of being too homogeneous or heterogeneous as a group. INTRODUCTION and Lilien, 2008).
