Thanks for you answer Eric!
In your example its actually an attorney getting the .attorney extension so it makes sense. But what if I was selling shoes online, would it make a difference if my site would be Myshoebrand.com or Myshoebrand.world? Or even Shoeshop.com or Shoeshop.world (if I want to rank for Shoe shop)?
I know Google stated that all domain extensions have just as good a chance of ranking as any other. But as Bill Hartzer also writes: we can't always take their word for it: we need to see proof.
