Little Yayas: I track my stats on statcounter.com and I sometimes use https://www.google.com/analytics. I like how Google Analytics lets you see where your traffic is coming from and gives you a bit more detail. This is great because you can monitor where your traffic is coming from and then make sure that you continue doing that. For example I get a lot of my giveaway traffic from OLS, so it would be a good idea to continue posting my giveaways there.
