Creating Social Contagion through Viral Product Design: A Randomized Trial of Peer Influence in Networks

  title={Creating Social Contagion through Viral Product Design: A Randomized Trial of Peer Influence in Networks},
  author={Sinan Aral and Dylan Walker},
  journal={Manag. Sci.},
We examine how firms can create word-of-mouth peer influence and social contagion by designing viral features into their products and marketing campaigns. To econometrically identify the effectiveness of different viral features in creating social contagion, we designed and conducted a randomized field experiment involving the 1.4 million friends of 9,687 experimental users on We find that viral features generate econometrically identifiable peer influence and social contagion… Expand
Identifying Influential and Susceptible Individuals in Social Networks: Evidence from a Randomized Experiment
Perhaps the two most important and elusive questions at the heart of viral marketing today are when is peer-to-peer influence mobilized and who are the influentials that most effectively mobilize andExpand
Identifying Social Influence in Viral Products Using Randomization over a Large Mobile Network
This paper analyzes the role of social influence in the diffusion of telecom related products across social networks. We study a subset of the products deployed by a large European mobile carrier andExpand
Creating Social Contagion Through Firm Mediated Message Design: Evidence from a Randomized Field Experiment
We study whether and how a firm can enhance social contagion by simply varying the message shared by customers with their friends. We focus on two key components of information contained in theExpand
Tie Strength, Embeddedness & Social Influence: Evidence from a Large Scale Networked Experiment
Understanding peer influence in networks is critical to estimating product demand and diffusion, creating effective viral marketing, and designing ‘network interventions’ to promote positive socialExpand
Tie Strength, Embeddedness, and Social Influence: A Large-Scale Networked Experiment
This work presents some of the first large-scale in vivo experimental evidence investigating the social and structural moderators of peer influence in networks, and finds that both embeddedness and tie strength increase influence. Expand
Are Paid Subscriptions on Music Social Networks Contagious ? A Randomized Field Experiment
Demonstrating compelling causal evidence of the existence and strength of peer to peer influence in online social networks has become the holy grail of the modern research in online social networks.Expand

The study found that cascade depth is negatively associated with social contagion effects and positively associated with the effect of interest similarity on message sharing, indicating that influence-based and homophily-driven diffusion operate differently in cascades with different diffusion structures.

Viral Altruism? Generosity and Social Contagion in Online Networks
How do the social media affect the success of charitable promotional campaigns? We use individual-level longitudinal data and experimental data from a social-media application that facilitatesExpand
Engineering Social Contagions: Optimal Network Seeding in the Presence of Homophily
We use data on a real, large-scale social network of 27 million individuals interacting daily, together with the day-by-day adoption of a new mobile service product, to inform, build, and analyzeExpand
Network Size and Content Generation on Social Media Platforms
We study the effects of peer-group sizes on content generating and sharing in a large-scale and influential social media platform. User-generated content, particularly tweets in social media,Expand


Creating Contagious: How Social Networks and Item Characteristics Combine to Drive Persistent Social Epidemics
Why do certain cultural items capture persistent collective interest while others languish? This research integrates psychological and sociological perspectives to provide deeper insight into socialExpand
Integrating the Social Network to Diffusion Model and Evaluation of the Value of Hubs in the Adoption Process
In this paper we analytically study the effect of social hubs on the penetration of new products. Aggregating individual-level social network considerations to the market level, we identify boundaryExpand
Do Friends Influence Purchases in a Social Network?
Social networks, such as Facebook and Myspace have witnessed a rapid growth in their membership. Some of these businesses have tried an advertising-based model with very limited success. However,Expand
Distinguishing influence-based contagion from homophily-driven diffusion in dynamic networks
A dynamic matched sample estimation framework is developed to distinguish influence and homophily effects in dynamic networks, and this framework is applied to a global instant messaging network of 27.4 million users, finding that previous methods overestimate peer influence in product adoption decisions in this network by 300–700%, and thathomophily explains >50% of the perceived behavioral contagion.

Opinion Leadership and Social Contagion in New Product Diffusion
There is evidence of contagion operating over network ties, even after controlling for marketing effort and arbitrary systemwide changes, and sociometric and self-reported measures of leadership are weakly correlated and associated with different kinds of adoption-related behaviors. Expand
A Viral Branching Model for Predicting the Spread of Electronic Word of Mouth
The proposed viral branching model allows customers to participate in a viral marketing campaign by 1 opening a seeding e-mail from the organization, 2 opening a viral e-mails from a friend, and 3 responding to other marketing activities such as banners and offline advertising. Expand
Creating Social Contagion Through Viral Product Design
We examine how firms can create word-of-mouth peer influence and social contagion by designing viral features into their products and marketing campaigns. To econometrically identify the effectiven...
