I actually found it a bit difficult and confusing to answer this question. There are many variables including traffic, audience make-up, page rank, ad size, placement and more. The numbers are all over the map. I am happy to share my stats with this experiment.
My prediction originally was $2 a month. I wasn’t very optimistic. I read one post saying someone made $80 a month with very little traffic. It could be an urban myth though.
Apparently there are special words like mesothelioma which can get $25 per click! Who would have thunk such a thing? Advertising is a strange and curious beast. Almost everyone denies being swayed by advertising, yet it is one of the most influential business models on the web.
In hindsight, I shouldn’t have erased all those Windows 7 blue screen of death articles. It doubled my traffic. Oh well. I’ll take the ads down eventually, but I want to experiment and see what happens.
