For a franchise brand, that means planning St. Louis as several local markets, each with its own customers, search results and real estate costs.

Territories
St. Louis spreads across 15 counties, and each part of the metro behaves like its own market. Territories work best when they are sized on households and travel time, not on city or county lines.
Radius territory
Simple to write into the franchise agreement, and a good fit where customers come from a short distance, such as dense, walkable neighborhoods. In spread-out areas the same distance can hold very different numbers of customers.
Drive-time territory
Follows the roads and traffic patterns customers actually use, and can be sized on household counts so every owner starts with comparable demand. A good fit where most customers drive.
For franchise brands
A customer in Chesterfield and a customer in Clayton see different search results. Each St. Louis unit needs its own page on your franchise website, its own Google Business Profile and its own reviews.
