This is Aurélie Pols presentation at Strata London Conference last 11-13 November. It is in English and starts by revisiting the common best practices related to digital analytics in order to measure digital asset’s effectiveness to increase conversion, common data feeds between tools and possibly data flows between continents for analysis. These practices are then put in parallel with legal requirements, showing which steps need to be undertaken to assure legal compliance of said practices, how digital responsibles should be trained in data protection matters and what contracts are needed with both data providers & collectors so as to assure minimal liability for these routinely undertaken tasks. This presentation is NOT about security and goes beyond the over-blown cookie debate in order to highlight how the upcoming EU Personal Data Protection Regulation will influence digital analytics to hopefully start embracing Privacy by Design ways of working.
