IMS Health has used several indices to rank such companies as:
Achievement index: measures the absolute number of 'listeners' and is based on the number of people each channel reaches through likes, shares and re-tweets.
Relevance index: measures whether people think messages, or content, are relevant and/or useful. The index is based on the extent to which content is shared and transmitted across social networks.
Relationship index: it is a measure of interaction – back and forth of conversation – and a measure of the integration of consumers, or patients, with the pharmaceutical company. This index measures the level of interaction between a company and those who post, reply to or otherwise interact with company messages.
