I have a website filled with images of funny photos, celebrities photos Etc. I am getting about 40 K unique visits Per month, and about 70 K page views per month. Since the whole website is mainly about pictures, my CTR rate sucksss. I would like to know how much money I can make in a month from CPM(Cost Per Thousand impressions)advertising on the website. If you guys have any other advices for me please share as well. Thank you.
