How is the (estimated) Viewership of a mention computed?
The (estimated) Viewership for each mention is estimated with the help of an algorithm that combines a set of characteristic variables for the primary source with a set of variables specific to the secondary sources.
The variables specific to the primary source are: the medium number of visitors for a blog, the typology of the blog, its rank in top Zelist,
estimated average traffic based on their position in Zelist Top, corroborated with the medium traffic reported by Trafic.ro.
The term "secondary sources" refers to the takeover and spread of advertising messages by primary sources on blogs, Twitter or Facebook.
The variables of the secondary sources that are a part of the computing algorithm are: the number of potential visitors generated by each takeover and by the importance of the secondary source (be that its rank on Zelist, the number of Twitter followers and the number of fans/members on Facebook).
In that which concerns takeovers and the dissemination of messages on Facebook, we take into account the degree of interaction of that message on the page on which it was posted on, related to the total number of fans/members.
