tamplatepanic cancer HPKIt has been a long time since I made my first learn about adsense. Like many other adsense publisher, I also targeted high paying keywords and that time many people tried to find this high paying keywords or what called HPK. Well until now I guess. Mesothelioma cancer was one of the highest paying keywords. It was too bad that it was very difficult for me to target it. It was simply because I don’t really understand about that term.
