I see the scripts in the control panel thing but I don't know how to insert them onto my site.
also, should they be only on the home page or on every page?
thanks
It should at every publicly visible page. Not needed on pages that only you can see like the admin panel at forums etc. What type of package do you have?
As vigge_sWe has told you, the ads need to be in ALL the pages that public have access to.
As you've the "Advanced" package, the ads can be put in any location.
You can use the Personal or Advanced ad code.
