The trail does not break at the jump to WhatsApp
The whole chain stays tied together: the ad that was clicked, the page that was seen, the conversation that started and the appointment that came out of it. The person never has to fill in a form or say where they came from.
- Google’s click identifier is captured on arrival and survives the visit.
- When the WhatsApp button is tapped, the message goes out with a short reference tying that conversation to that visit.
- When the conversation turns into an appointment, the appointment is linked to the ad. With nothing typed by hand at any point.
