Hi,
I got a google code regarding mobile advertising. and I would insert it in all pages. what file I have to insert and thank you.
Here the received message :
Insert the ad code in the <head> tag (or the top of the <body> tag) of the pages you want to view the ads. The same ad code applies to all pages and sites. You will not have to change it, even if you change the settings of your ads to the page level.
