When a new product is introduced, the first hurdle is establishing consumer awareness of the item. After all, they won't buy it if they don't know it exists! Product trial needs to occur so consumers gain initial experiences with the item. Then repeat purchases need to be monitored. The measurement of awareness, trial and repeat usage allows PAR clients to understand market share and interest in the brand. When the study is repeated, it is possible to begin trending the data, allowing your marketing department to understand when and how to improve product promotion.

Longitudinal studies monitor changes in market share, perceptions of the product, or perhaps corporate image. PAR has conducted numerous studies of this sort for a wide array of clients ranging from banking, to healthcare, to consumer package goods of all sorts.
