Do not buy New Albany clicks if you can only act on the Kentucky side
The fastest way to waste a commercial real estate budget in this metro is to advertise across a state line you are not licensed to work on.
Southern Indiana sits inside the same radius as most of Jefferson County. Draw a thirty mile circle around a downtown office and you have bought Clark and Floyd Counties whether you meant to or not.
Licensing and registration requirements differ by state and are worth confirming with your broker of record and your own counsel before a single ad runs. What matters for the account is simpler: decide what you can act on, then make the targeting say so.
If you do serve both sides, do not blend them. Kentucky and Indiana inquiries deserve separate campaigns, separate landing pages and separate reporting, because the buyer, the process and the competitive set are all different.
If you serve one side, exclude the other explicitly rather than relying on a radius to do it. Radius targeting in a river metro is imprecise in exactly the direction that costs you money.
