Google Adsense is great!
Pros: Without having to worry the quality or type of ads, Google will take care of target ads and target audience. It's a one time effort for you to get it approved.
Cons: if your target audience is Indians, then the earnings through google Adsense will be very less, compared to other countries(especially US & Europe).
But, in either case, it's still a great way to simply earn from your blog.
