-- Facebook Data Valuation Tool (FDVT) --
Would you like to know the money you are generating for Facebook?


The FDVT extensions provides Facebook end users with an estimation of the economic value they are generating while browsing in the Facebook site. Different users will generate different economic value depending on their demographic parameters, their interests, the time they spend in Facebook, etc. In order to use the FDVT the user has to undergo a registration process where he/she has to provide the following information: Location (compulsory), Gender (optional), Age (optional), Birthday (optional) and Civil Status (optional). This information allows the FDVT creating a unique profile associated to the user. Therefore, each user will receive a personalised estimation of the money he/she is generating for Facebook. The Facebook identity of the user will be completely anonymous. This means that we neither collect nor store any data item that allows identifying the Facebook identity of the end-user.

The FDVT shows the following information:

- Session ads: The total number of ads displayed in the current session.
-Value: An estimation of the value generated out of the ads displayed

- Ads Clicked: The total number of ads clicked by the user in the current session.
-Value: An estimation of the value generated out of the ads clicked.
