РОР, РОS Research
Registering products and brands that consumers intend to purchase before entering a store, as well as the contents of the actual purchase. Data collection is done with the help of especially trained interviewers who stand at the entrance of predetermined retail centres and interview customers that exit the store.
Place of purchase (POP) and place of sale (POS) research is suitable for assessing the effectiveness of advertising campaigns/promotions; the share of the advertised product is compared to the market share of all products in the same category. Usually the research project is carried out in two stages – before and after the campaign.
