conversion tracking
Do you mean how conversion tracking should be set up in GA4? You can refer this link [GA4] How to setup conversion in Google Analytics 4
As for the effective setting methods for B2B enterprises, you can refer to my suggestions.
Based on your website, here is an example of my setup for reference.
"Contact Us web browsing", the main operation optimization setting, the value per conversion is ￥1
"Email outbound click", the main action optimization setting, the value of each conversion is ￥3
"Form submission", main action optimization setting, value per conversion is ￥10
If you have "Whats App outbound clicks", the main action optimization setting, the value per conversion is ￥5
It is recommended that you also install the WhatsApp button, because some overseas users will contact WhatsApp directly.
You can adjust the conversion value for the things you want to focus on. The purpose of this is to let the system know which conversion things you pay more attention to, and then when you use Smart Bidding, you can use it to maximize the conversion value.
As for other web browsing data, you can set it as secondary for reference, and it will not have any impact on ad serving.
