The Dynamic numbers are ProxyNumber telephone mumbers dedicated to a single channel or advertising campaign.  What is the advantage of having so many separate numbers? By assigning a different number, thanks to call tracking, it is possible to understand what is working and what is not, which campaigns to push and which are not performing. It is a precise and effective measurement system of the performance of the channels we are using or of the campaigns in which we are investing money. The service is ideal for real estate agencies, car dealers but also for vertical portals in the same sectors. It is also suitable for use by marketing agencies, which have the ability to measure the revenue of digital advertising spaces without margin of error, even being able to trace the path of the individual user. Ultimately, this type of use of ProxyNumber allows you to focus the spending of resources on what works, optimizing budget allocation and allowing decisions based on reliable data.
