I searched for a service that would include call tracking, callback, and end-to-end analytics for a long time. First of all, the interface is really great and intuitive – after working with it for a bit, everything becomes clear, and if needed, you can always reach out to a manager for help. Secondly, it's nice that the program allows users to set their own rules. The end-to-end analytics helped us get rid of ineffective advertising and unnecessary expenses. Thanks to call tracking, the website's conversion rate increased, as customers with questions started calling operators, which in turn boosts the sales percentage. The price is also quite reasonable. After a call ends, information about the user and which advertisement brought them to the site is displayed in the personal account. Overall, the service is truly very convenient.
