One of the most important areas of social media measurement is engagement; however, industry measures that equate engagement with social media interactions are often inadequate. This study contributes to the ongoing discussion about how to conceptualize engagement and introduces a valid, reliable scale for measuring blog engagement that is grounded in qualitative research. The qualitative research resulted in four dimensions; however, one of the dimensions did not make it through the data analysis process. The resulting blog engagement scale consists of presence, virality, and utility dimensions.
