Recently, one of ROI Solutions’ clients approached us excitedly about the potential of “viral marketing” and asked us to consider it during our development of the client’s 2008 interactive marketing plan. We, of course, happily agreed to do so.
At the outset of the plan development process, ROI Solutions and the client’s planning team jointly defined two key terms:
Viral, adj.: exhibiting large-scale, word-of-mouth communications among consumers.
Viral Marketing, n.: the facilitation of traditional word-of-mouth marketing among consumers by means of highly-scalable interactive communication tools, such as email, mobile messaging, and social networks.
By the end of the plan development process, our client arrived at three important conclusions about viral marketing. The sections that follow identify and describe some of the short-comings of viral marketing that our client considered to arrive at these conclusions as well as to make strategic choices about the role of viral marketing in the client’s 2008 interactive marketing plan.
Lack of Omniscience: The Inherent Flaw in Measuring Viral Consumer Behavior
During the planning process, ROI Solutions noted to our client that viral consumer behavior can occur almost anywhere that consumers use interactive technologies. However, we emphasized to our client that viral consumer behavior can only be measured and recorded when a predefined measurement solution is in place before any intended viral consumer behavior starts. Such a measurement solution typically takes the form of a database-driven application that must be designed, developed, tested, and implemented to record viral consumer behavior in the database before the start of an interactive marketing campaign. An example application for viral consumer behavior is a “Forward-to-a-Friend” email application that our client might make available on a branded micro site to enable consumers to promote a sweepstakes among them.
With the implementation of a predefined measurement solution required to record viral consumer behavior, it follows then that any and all viral consumer behavior occurring outside of the predefined measurement solution, or before its implementation, will go unmeasured and unreported. Continuing the example from above, if a consumer informs one or more consumers about our client’s sweepstakes via email but does so using Outlook, Thunderbird, Entourage, or some other desktop email program instead of our client’s “Forward-to-a-Friend” email application, that consumer’s viral behavior will go unrecorded and unreported by our client’s “Forward-to-a-Friend” email application. In this manner, the actual viral consumer behavior that occurs in total during our client’s campaign is not fully reflected in the measured and reported results that the client receives and considers for performance evaluation.
When it is known or believed that any viral consumer behavior occurred outside of a predefined measurement solution, the viral consumer behavior measured and reported by the predefined measurement solution is understated. In other words, more viral consumer behavior likely occurred but a marketer could not measure it or report it (perhaps only an omniscient being can measure and report all viral consumer behavior that occurred). Any management decisions to be made based on viral metrics must take into account that such metrics understate the total viral consumer behavior that occurred. In this manner, any reported viral metric serves as a lower bound on actual viral consumer behavior – e.g., “Consumers sent at least 1,329,538 viral email messages among them over the course of the six-week campaign.” ROI Solutions believes it is important that our clients appreciate this nuance about reported viral marketing results before they make substantive decisions regarding a marketing campaign or program featuring viral marketing as a tactic.
Two Lower Bound Measures of Viral Consumer Behavior
Most viral consumer behavior occurs through email or mobile messages. In such cases, viral consumer behavior features a “sender” who “distributes” a message to at least one “recipient” of that message.
Below, ROI Solutions defines two common performance indicators for viral consumer behavior facilitated through email messaging:
- Viral Email Distribution Counts
The number of emails sent via a Forward-To-A-Friend application during a specific time period
- Viral Email Sender Counts
The number of consumers who used a Forward-To-A-Friend application to send emails to other consumers during a specific time period.
Below, ROI Solutions defines two common performance indicators for viral consumer behavior facilitated through mobile messaging:
- Viral Mobile Distribution Counts
The number of mobile messages sent via a Forward-To-A-Friend application during a specific time period.
- Viral Mobile Sender Counts
The number of consumers who used a Forward-To-A-Friend application to send mobile messages to other consumers during a specific time period.
In the case of social networking (insofar as it stands today), measurable viral consumer behavior takes place largely through “widgets”:
Widget, n.: A snippet of code that, once installed in a consumer’s profile page on a social network, transforms into a value-added application that provides benefits to the consumer and/or to visitors to the consumer’s profile page.
Widgets become viral when a consumer in a social network decides to become a “sender” who “distributes” a widget’s “invite” to at least one other consumer, or “recipient,” in his or her social network. The invite gives the recipient the opportunity to install the same widget in his or her own profile page. Of course, the recipient may choose to reject the invitation to install the widget; nonetheless, viral consumer behavior has occurred – the sender distributed the invite to the recipient.
Below, ROI Solutions defines two common performance indicators for viral consumer behavior facilitated through social networking:
- Widget Invite Distribution Counts
The number of invites sent via a widget’s Invite-A-Friend feature during a specific time period.
- Widget Invite Sender Counts
The number of consumers who used a widget’s Invite-A-Friend feature during a specific time period.
For our client’s 2008 plan, ROI Solutions recommended that our client use two consolidated measures of viral consumer behavior, Viral Impression Counts and Viral Sender Counts. The Viral Impression Counts metric simply reflects the sum of all distribution counts that can be recorded and reported by our client’s predefined measurement solutions during a given period:
Viral Impression Counts
= Viral Email Distribution Counts + Viral Mobile Distribution Counts + Widget Invite Distribution Counts
The Viral Impression Counts metric serves as the measurable lower bound for the number of word-of-mouth communications sent by consumers to other consumers as part of our client’s interactive marketing campaigns. Clearly, other types of word-of-mouth distribution counts could be added to this sum, as warranted.
Similarly, the Viral Sender Counts metric simply reflects the sum of all sender counts that can be recorded and reported by our client’s predefined measurement solutions during a given period:
Viral Sender Counts
= Viral Email Sender Counts + Viral Mobile Sender Counts + Widget Invite Sender Counts
The Viral Sender Counts metric serves as the measurable lower bound for the number of senders of word-of-mouth communications as part of our client’s interactive marketing campaigns. Clearly, other types of word-of-mouth sender counts could be added to this sum, as warranted.
One Client’s Conclusions and Choices Regarding Viral Marketing
By the end of the plan development process, ROI Solutions’ client arrived at three important conclusions about viral marketing:
- Viral marketing is not a marketing strategy in and of itself; rather, viral marketing is simply a tactic: it is one of several possible means to achieve the desired end (e.g., sales, leads, lift in brand awareness, opt-ins, registrations, etc.) of any campaign type (e.g., Direct Response, Brand Awareness, Brand Response, etc.)
- Viral marketing can be engineered into the design of most interactive marketing campaigns regardless of campaign type
- Viral consumer behavior can only be measured and recorded for performance evaluation purposes if a predefined measurement solution has been engineered into the design of the interactive marketing campaign, and even then, not all viral consumer behavior will be measured and recorded
Based on these conclusions, our client made two important choices about how to incorporate viral marketing into its 2008 interactive marketing plan. First, the client chose to use viral marketing as a tactic only – interactive marketing’s ability to facilitate viral communications among consumers is powerful, but its power is only useful if it helps generate more important marketing outcomes, such as sales transactions, qualified leads, opt-ins, registrations, and/or a lift in brand awareness. Second, our client chose to not elevate any measures of viral consumer behavior, such as Viral Impression Counts and Viral Sender Counts, to the level of Key Performance Indicator (KPI) for any of its interactive marketing campaigns in 2008; the client understood that marketing outcomes of a higher order than viral metrics make more appropriate KPIs for interactive marketing campaigns.
ROI Solutions seconds our client’s conclusions and choices regarding viral marketing. Yes, much viral consumer behavior goes unmeasured and unreported, leaving the interactive marketer with only a measured lower bound to a complete viral marketing story. Still, this inherent flaw in the measurement and reporting of viral marketing results is acceptable: while it remains an important tactic in a marketer’s bag of interactive marketing tricks, viral marketing is simply a means to an end, not the end itself.
