Hello

I would like to have google analytics data on my login page. Because i want to put ads on there. (I also want to track my index.php to see the differences). I would prefer a solution that does not include installing ad management or something like that.
I'm just unsure weather to use the analytics script or the php include tag (with a separate file). Where exactly they would have to be placed. And if i should tell google analytics that my default page is password_protect.php or index.php?
