I want to share my experience using the UTMSTAT service in the field of online education. In short: it is a reliable tool for end-to-end analytics that effectively solves its tasks at an acceptable price. Pros: + it fully meets the set objectives. All requests are tracked accurately. It is clear which advertising campaigns bring profit and which ones incur losses. + an excellent analytical bot that offers truly useful recommendations. + the cost is 2-3 times lower than that of large services, which is critical for small businesses. Cons: — the design of the service interface needs improvement. The mobile version also requires refinement. — if you connect it yourself, you will have to put in some effort for implementation. However, they offer a turnkey installation option (and it's free). I was interested in figuring it out on my own and understanding how everything works. In the end: this service is an essential tool for any business engaged in internet advertising.
