Call-tracking is based on the substitution of phone numbers on your site. Instead of your company's contact phone number, it shows the website visitor a fake number. Then it matches it with a specific advertising source or user visit. We will describe the substitution principle in more detail below, but for now, let’s focus on how call tracking works.

So, the client went to your site, for example, from an advertisement:

He sees a fake phone number and calls.
The call goes to the virtual PBX of the call tracking service, and then is forwarded to your permanent phone number.
After the end of the call, all information about it falls into the call log from which you can generate reports.

What is call tracking service ?
Currently, there are three types of call tracking:

Classic or static call tracking.
Dynamic call tracking.
Combined call tracking.

Static (classic) call tracking
Assigns a separate phone number to each ad source

Dynamic call tracking
Shows different phone numbers to different site visitors.
Matches a call with a specific visit.
Allows you to trace the advertising source of the call in detail - down to the campaign and the keyword.
It requires more numbers than the static one, because visitors who are on the site at the same time need to be shown different phone numbers.

Combined call tracking
This is the simultaneous use of two types of call tracking.
It is used when more detailed information is needed for some channels, while data about the source is enough for others (for example, dynamic call tracking for contextual advertising, and static for offline advertising).
Allows you to use fewer phone numbers for tracking than dynamic call tracking.
