Recently came across some of the affiliate networks like Vcommision. These type of ads work well in India. And the conversion rate for such networks needs to be good. You can see that more such affiliate network opens up then that can be really good for the revenue. So it makes sense to have account on such types of ads there. I prefer media.net and Adsense even in this case for monetization.
The .in and .io domain name extentions along with .com are very popular in the coin industry, for faucet monetization adsense is many used.
Actually, the .io which stands for indian ocean and on the internet can also mean input, output is very popular.
