Hello! Today is a wonderful day to find out once and for all, what is ROI. Of course, if you still do not know what it is. And we sincerely hope that our third issue of the online-marketing comics will help you with this.
By the way, have you already read the other issues of comics? In the issue of “What is a CPM, CPC, CPA” we used gif images. Did you like it?
Have a nice day and a high ROI!
