To clarify and organize the information related to potential measures of viral campaigns, the key measurement possibilities should be considered in relation to the objectives formulated for the viral campaign. In this sense, some of the key cognitive outcomes of viral marketing activities can include measures such as the number of views, clicks, and hits for specific content, as well as the number of shares in social media, such as likes on Facebook or retweets on Twitter, which demonstrate that consumers processed the information received through the marketing message.
Measures such as the number of reviews for a product or the number of members for a campaign webpage quantify the number of individuals who have acknowledged the information provided by marketers. Besides statistics that are related to online traffic, surveys can assess the degree of product or brand knowledge, though this type of measurement is more complicated and requires more resources.
