A Williamson County requirement will never type the word Austin
Occupiers search the place the building sits, and much of the region's inventory sits in Round Rock, Pflugerville, Kyle and Buda rather than inside the city limits.
A tenant looking for 20,000 square feet of flex space near a workforce in Round Rock searches Round Rock. A retail group scouting a pad near Kyle searches Kyle. Neither one types the metro name, and a single page called Austin commercial real estate serves neither of them.
Give Travis, Williamson and Hays counties their own pages, then give the submarkets you actually work their own pages underneath: Round Rock, Georgetown, Cedar Park, Leander and Pflugerville on one side, Kyle, Buda, San Marcos and Dripping Springs on another, Mueller, East Austin and South Congress inside the city.
A submarket page earns its place by carrying something. Current availability, the asset classes that trade there, drive times to the corridors people care about, and the names of your brokers who cover it. A page with three paragraphs and a stock photo does nothing for you, and a site full of them is a site with nothing worth ranking.
Publish only the ones you can keep current. Six submarket pages that are right beat twenty that quietly went stale in the spring.
