The first thing that a BGP speaking router does is to look up the destination IP address in its table of autonomous system numbers (ASNs). An AS is a group of networks that are all under the control of the same policy maker. If you get your internet connectivity from one ISP, you fit in their AS. If you talk to multiple ISPs, you need to be your own AS (and have routable IP addresses assigned to that AS). Finally, the largest networks may be a confederation of several AS, either as a result of purchases or by deliberate policy.
BGP transmits reachability information by building paths of AS that are neighbors. Then, typically, it selects the shortest path of AS hops. (There are a lot of knobs to twiddle with here, both on the advertising side and on the deciding side.)
BGP doesn't care or know about numbers of router hops, just the number of AS between here and there.
There are lots of "network engineer in a box" products that map out performance and then twiddle knobs on your BGP router to select for best performance (or least cost, if some of your paths are more expensive than others.)
