Quantifying Campaign Ripple Effect Within a Customer's Social Network

Social network of targeted users increase usage and less likely to churn, according to research from Columbia Business School and Amplero


Amplero Principal Research Software Engineer Matt Danielson partnered with researchers from Columbia University’s Business School to quantify the ripple effect of personalized marketing campaigns on non-targeted customers in the targeted customer’s network.

Leveraging the Amplero Digital Intelligence Platform to deliver highly contextual messaging and study the behavior of nearly 6,000 mobile customers, they found that social connections of targeted customers increased usage and were less likely to churn due to a campaign that was neither targeted at them nor offered them any direct incentives.

“This research has considerable implications for the way marketers think about their customer relationships,” said Amplero CEO Olly Downs, PhD. “While most marketers are focused only on the behavior of specifically-targeted customers in a given campaign, machine learning-powered social relationship-aware technology enables continuously-optimized interactions with the customer that take into account how they themselves interact with one another.”

  • A single-minded focus on gaining revenue from one customer misses the opportunity to tap into one of their most important assets: their connections
  • Measuring ROI on campaigns only to targeted customers discounts what is achieved through their friends and connections


Traditionally, companies look to a customer's lifetime value (CLV) -- a measure of how profitable their relationship with an individual will be over time -- but new research from Columbia Business School indicates that traditional CLV measures can sharply underestimate the true value of the connected consumer. Today's social networks can turn regular people -- not necessarily big spenders -- into major influencers.

The research was conducted by Columbia Business School professors of marketing, Eva Ascarza and Oded Netzer, both of whom specialize in using data to gain a deeper understanding of customer behavior and models predicting changes in that behavior.

"Marketers are missing out on a substantial piece of the pie if their customer relationship marketing (CRM) campaigns only consider the profitability generated by their targeted customers. CRM campaigns also need to include and measure the changes in activity among those connected to the targets," said Ascarza.

Firms and industries with network-based products and services such as telecommunications, online video games, or file-sharing services like Dropbox are naturally positioned to take advantage of the connections among their users. But the benefits extend to more traditional industries as well.

"Because there is a social component to many types of goods and services -- restaurants, health clubs, golf courses -- there is an upside for these types of businesses to also consider the connections of their customers and invest effort into collecting that type of data," said Netzer.

The study Beyond the Target Consumer: Social Effects of CRM Campaigns was co-authored with Peter Ebbes from HEC Paris and Matt Danielson from the company Amplero, The objective was to investigate whether targeted CRM campaigns that aimed at changing the behavior of specific customers also affected the behavior of the targeted customers' connections, who were not targeted themselves. The study proved that not only was the behavior of the customers' connections affected, but also by ignoring their targeted consumers' social network, marketers are leaving a significant amount of money on the table. Even if the original targets' responses were lower than projected and generated less revenue, the response from their social network connections can more than make up for it.
