Clark and Floyd County buildings never surface in a Louisville search
A tenant hunting industrial space in Jeffersonville is not typing your city name, and no amount of on-page work inside your Louisville pages will change that.
Southern Indiana is the same metro and a different search market. Jeffersonville, New Albany and Clarksville have their own names, their own county names, and their own search behavior. If your only Indiana coverage is a line in a footer, you are invisible to half the metro's occupiers.
The fix is structural, not clever. Give Clark County and Floyd County real pages with real inventory, written by someone who has walked the buildings. Name the cities. Name the river crossings people use. Link the Indiana pages to each other rather than burying them under a Kentucky parent.
Be honest about what you can do there. Brokerage licensing differs by state and it is worth confirming your firm's standing with your broker of record and your own counsel before you publish a page that implies representation. A page that says plainly "we list in Kentucky and refer in Indiana" costs you nothing and saves you a lot of wasted inbound.
One more thing brokerages miss: an occupier weighing both sides is comparing tax and incentive treatment, and those differ across the line. You do not have to explain the rules. You do have to acknowledge that two sets exist and point the reader to the right authority.
