i don't have idea for that, because to make money for blog including highest paying keyword need many more effort.
why does it matter? Do you actually think your blog can compete with those big guys also targetting the high paying keywords?
Please pay attention for the "Smart Pricing" which google use. it depends on how many visitors you get and where they are from and many more things I'm searching for right now
hey, you should not make fun of religion. It is a bad attitude guys.. just remind you I think to make money from high paying keyword is such a hard thing. You better build site based on what you like and give your best on it, then traffic & money will follow your hard effort. It is easier than make a website based on high paying keyword.
Let them do it... they wont ever succeed - which means less competition for those who have common sense and actual knowledge
I believe US is the highest paying nation, simply because the total number of advertisers most likely willing to spend a HUGE amount of money for adsense is most likely located in the US. Still, getting high earnings in adsense is not simply about targeting a country, it's more about targeting your audience and specific keywords
for countries you will get good earnings where the currency rate is high. for industry search for high cmpetition. which is having good profit margin.
first you should think what field you like, then study the main keywords of the field, last try and test the results.
