Hi Patrick,
Thank you for this response.
I have one more question, looking at my screen cast:
http://screencast.com/t/GDpNp0PE
This is the result to the landing page to ''index''
1099 visitors are ( not set)
I can say my Adword account is link to G.A. because my campaign ''filtre fournaise_2'' has 359 visitors...
Can you say they are all user that use ''private browsing'' option from there browser? or other?
Thank you,
Jean
