St. Louis, MOReviewed September 5, 2026

One metro, two governments, and a market most agencies misread

Healthcare, plant science, aircraft and mapping technology. Plus a quirk most outsiders miss: the city and the county are two separate places, and most of the big 'St. Louis' companies are in the county.

What's actually different about Greater St. Louis

Greater St. Louis is home to about 2.8 million people across Missouri and Illinois. The thing outsiders usually get wrong is the map. Since 1876, the City of St. Louis has been separate from St. Louis County, and the city itself has only about 280,000 residents.

That matters because many famous 'St. Louis' companies are in the county. Enterprise and Centene are in Clayton. Edward Jones has its main campus in Des Peres. Bayer's crop science business, the former Monsanto, is in Creve Coeur, next to the Danforth Plant Science Center, the heart of the region's ag-tech scene.

The city has its own anchors. Anheuser-Busch still brews in Soulard, though its parent company, AB InBev, is based in Belgium. BJC HealthCare and Washington University School of Medicine run one of the country's biggest medical centers. The Cortex district in Midtown is the main hub for tech and bioscience startups.

Two more things shape the market. The National Geospatial-Intelligence Agency's new NGA West campus in north St. Louis, a federal project of roughly $1.7 billion, is drawing mapping and defense-tech firms to the city. And Boeing's large defense plant near Lambert airport supports a long chain of aerospace suppliers. Across the river, the Illinois side (Belleville, Edwardsville, O'Fallon) is its own market, with Scott Air Force Base nearby.

City or county? Decide on purpose

People type 'St. Louis' for the whole region, but customers live in the city, St. Louis County and St. Charles County. If you only build one 'St. Louis' page, competitors pick up the searches for Clayton, Chesterfield and O'Fallon.

Web design searches are easy to win

Google's own data rates the main St. Louis web design and development searches as low competition. 'Marketing agency' searches are tougher. A fast, well-built site with proper local pages can rank here without a huge budget.

Defense buyers read websites differently

Suppliers to NGA West and Boeing win work with capability statements, certifications and past performance. A contracting officer wants clearances, NAICS codes and proof you've done similar work. Polished brand copy doesn't help.

Illinois is a separate market

Belleville, Edwardsville and O'Fallon, Illinois search and buy differently from the Missouri side, and Scott Air Force Base shapes demand there. Campaigns aimed only at 'St. Louis' miss a lot of those buyers.

In their words

The part clients actually remember.

Not the reports. The uncomfortable conversation that changed the trajectory.

I spent the first two months defending our production values. Nobody was attacking them. They were pointing out that four assets a month is a math problem you cannot solve by making each one better. That distinction took me too long to hear.
Anders Lindholm-BeaufortBrand Director, Kalder
We asked them to scope a portal with about forty features. They came back and said seventy percent of our call volume was three things, and we should build those and nothing else. I pushed back hard. They were right, and we shipped in ten weeks instead of a year.
Marguerite Oyelowo-BakkeOperations Director, Verrick Industrial
The uncomfortable part was being told our content was inoffensive to the point of being pointless. They wanted us to say things competitors would disagree with. That felt risky for a consultancy and it turned out to be the only thing that worked.
