Which RPM is good for my website?
Safe response for your question is “it depends” if you make advertising on your site then your RPM depends on segment and how much advertisers is here. If your website is in niche where are higher CPM then you will have higher RPM. Usually these are segments where there are high margins and a lot of money. That’s often where you make the most money. On the other hand, in segments where there is no demand, you will unfortunately earn less.
