That doesnt make sense, mesothelioma is an obscure disease caused by asbestos, which again is not found in the modern industries. I dont understand why it should pay highest when there are other better keywords to target.
Agree. also it doesn't have lots of competitors on Google ( around 6 mil) keywords that generate 1$ per click is very hard to rank for.
Advertisers are willing to pay a lot for clicks from that keyword because the advertisers are lawyers who want to sue people who caused the cancer for millions.
So what? I have keywords that give me 5$ per click. And should i start once a week a topic about that?
