I have a client who wants to do lead conversion tracking but does not have a field based form setup on their website. The only way they receive leads is by Phone calls and Emails. My first thought is that the Email link should generate a hidden iframe with the javascript tracking code. Another issue is that we do not control the clients website. Does anyone have any other suggestions?
You can try an affiliate script setup at the clients website. I would recommend affiliate pro script. But if the most leads have to come by phone calls it is hard to track how much leads you have send. But you can always ask the customers where they have read the advertisement, to keep track where they came from.
