Voluum is a tracking system that I use more frequently. It is very friendly, but the package that recognizes fake traffic is a bit expensive. It can do all the data of the API traffic platform with one click, which is my satisfaction. Generally, other or team connection may return some reports of target and cost. I do n’t need to worry about these things when using Voluum. I can see the budget consumed by the browser model of the traffic platform campaign and which browser model can be seen in Voluum. Analysis data. Of course, there are some defects, for example, some friends have too high reaction point loss. In fact, my test is okay, 10% -15% can still be accepted, mainly depends on whether the ROI can support the starting point loss. I hope they can be cheaper.
