Is it now 100 subscribers before you can now get a youtube URL? I registered a new youtube channel for someone else about 10 months ago and it said I needed 500 subs before I could register a youtube URL. Good for you getting it sorted. Back when I opened my youtube account in 2013 you could get your youtube URL straight off the bat. Also another handy tip you'll find with ranking your channel in google is when you are putting the tags in your videos, always add your youtube name in their too. I don't know how much of the world this works in but in the UK if you search my username "Bits Of Ben" in regular google, my channel always comes out top of the searches and I've only got 519 subs right now. Hope this helps!
