been looking around for a possibility to utilize dynamic telephone number insertion for my adwords campaign but I couldn't find a workable solution to dyanmically show telephone numbers on my site.
If visitor comes to my site through campaign A, a cookie is saved on his computer and, depending on this data, a telephone number is displayed. In this case telephone number A.
Does anyone know a piece of software that already does this? I can imagine, that it wouldn't be too difficult to set up.
