one side at a time or both?

I EBF my almost 8 week old daughter. What I do is feed her on one side and alternate the side on her next feeding. She feeds with a gap of 2-3 hours. My theory is that this way she'll a) empty my breast so my body makes more b) gets both fore and hind milk 
But every article on increasing breast milk says to feed on both sides. 
Now how will I know when to switch sides? Also is my method alright or does feeding on both sides per feeding actually better at increasing supply?
