BT has an advantage on OIB in that they carry a lot of types of boats which generates traffic through a variety of keywords. OIB obviously specializes in inboards and can only generate search traffic through related searches. Which is why OIB will never be able to compete on sheer traffic volume with a site like BT.
However, WRT keywords like: tige boats, used wakeboard boats, ski nautique, used mastercraft boats, used malibu boats, etc etc etc, type them into google and I think you will find that our site has a clear advantage over all of the others. It just takes a while to get that brand recognition
