Important: dynamic call tracking means that all links in ads will use UTM tags. Without them, you won’t be able to get the required amount of information.
Operating principle:
It is necessary to define the advertising channels that will be controlled. Their number is limited only by the budget - the cost of the system depends on the number of numbers.
Assign an individual number to each controlled group.
Install the script on the site that receives traffic from advertising channels. It will identify each user and show the desired phone number.
Should you use call tracking?
Like any technology, call tracking has its drawbacks. Among them:
high costs when using multiple advertising channels or high traffic;
Refusal of the service means disconnecting all numbers. Then part of the deferred demand will be lost - some clients could have written down these numbers;
If you miscalculate the call volume, the accuracy of the analytics will drop - there simply won't be enough open sessions for the numbers.
But there are also a number of advantages:
the most complete analytics of each channel - this advantage is the most important and determines the value of the technology;
integration with Google, Yandex and popular CRM systems;
wide scope for experiments: presentation, format, methods of advertising distribution;
budget allocation with focus on the most profitable sources.
