#google bought data from #mastercard to track the effectivness of their adds to influence your behaviour to consume.
It works like this:
- you see an add via google, but don't buy something
- you buy that product maybe 2 weeks later in a shopping store near by you
- if transaction data has connection to #mastercard, it can be send to google to be analysed
- google publishes succesfull 'offline' revunue to the one running the add
