If your site consists of different landings within the same domain and you want to differentiate and measure the number of contacts for each of them, you can paste different chatbot scripts in each one. This is achieved through Google Tag Manager. The steps to do this are:
1. Create Tag Manager and paste it into all the landings of your site.
2. Enter Tag Manager and create a "Trigger" for each landing and a "Tag".
3. The event (in our case the same chat) should be triggered every time someone enters the corresponding landing.
Ideally you should contact someone who is an expert on the subject to avoid inconveniences.
