Mental Penetration x Network Size = Mental Market Share
PrincipleBrand Strategy
Mental Availability has three measurable components. Mental Penetration is the share of category buyers with at least one CEP link to the brand. Network Size is the average number of CEP links among those buyers. Multiplied together they produce Mental Market Share, the brand's share of all CEP-brand linkages in the category.
