What can make big money in the online industry? I mean blogging, selling traffic, sending paid tweets, which one?

Here's what I think. Say if you have a large site with plenty of traffic then you should go for selling ads and what not. Because the traffic is too high so even if you make a few cents per visit the total amount of your income will be just great.

And if you have a small or average traffic yielding site then go for CPA offer. Because in that case even if you make just one sell per day it will be much bigger for you.
