Customer online data is collected via script on customer computers and is communicated to a server hosted by an organization, such as a card issuer. The customer online data communicated to the server is non-personally identifiable information (non-PII). In turn, the server aggregates the non-PII customer online data from the set of participating merchants. The server associates the received non-PII customer online data with non-PII demographic data. Other non-PII transaction data, such as previous transactions processed at a card issuer, also can be associated with the non-PII customer online data and non-PII demographic data. These associations are, in turn, used to create reports and to provide services to help merchants or other requesting organizations develop online strategies to drive click thru and conversion rates.
