For those of you looking to make money with knols, the most profitable categories of topics are those that are also highly contested keywords on the Internet. If you are fortunate enough to know a good deal of information on cars, insurance, and credit cards, then you can make a lot of money for writing a really good knol about them.

Say for instance you are a doctor that treats mesothelioma, a disease brought on by asbestos exposure. If you write a high quality knol with vital information about the disease then you would earn a far more larger amount of money than you would talking about a less competitive topic such as, say I don’t know, pumpkins.

Let me add however that you do not have to be a doctor to write about such things as mesothelioma, you just need to have the information to make a knol that is helpful and precise.
