This is one of the most popular "ready-made" systems for end-to-end analytics. In most projects I work on, custom systems are used, as they are developed individually for specific tasks and allow for more detailed statistics in the necessary aspects. If there is no such need, then with the right setup, Roistat can fully meet all data requests needed for analysis and decision-making. Data analysis is available, including ROI calculations for individual traffic channels, products, and managers. A variety of additional tools are also offered: lead catcher, online chat, call tracking, A/B testing, ad bid management, and virtual PBX. Drawbacks: — the prices are not the most affordable — it’s difficult to quickly figure it out on your own if you haven't studied the system before (it's better to order setup from Roistat specialists).
