Good advice but looking at keywords, i don't think this is going to work. Indian advertiser get away with peanuts because of almost Nil competition. Anyway Credit cards pays well because of many indian banks competing.
Try Matrimony/Jobs/Finance/Stock Market/Credit Cards/Technology/Gadgets these keywords pay nice.., and never ever try Indian Entertainment niche for making money as it is the worst paying niche
I am yet to come across any keyword that pays more than 40 rs cpc. most are around 4 - 10 rs cpc range.
