Thanks Jay, my only regret is I went ahead of myself and bought 3 websites from godady before learning about choosing websites.I did not pick the best names as i was not too sure of my niche either.

3 domains i mean

You know, I have at least a dozen domains... a couple I use, on is my name (made sure to claim that) and the rest are ones I bought either at 2AM in the morning, or pulled over the side of the road because I thought it was a good idea... and I have no idea what I'll use them for, lol.
Most of mine are from GoDaddy as well, but I have some I bought here. I do all my hosting here except for an older one I still have at Bluehost.
It's okay to have a couple extra though. I use a couple to try things out, and test things to make sure they work before I do anything dumb and break my main sites.
Even tomorrow I'm thinking of messing with some code, but I'll try it out on a test site first.
So those other sites might come in handy.
Not sure if it mentions in the training (been a while since I've gone through it), but try to purchase a .com domain as those are usually the ones you see ranking on page 1.
