FAQ

Are St Louis CPMs really cheaper than Kansas City?
Marginally — typically 5-10% cheaper on CPM. Both Missouri markets are affordable.

Should I target St Louis City or the full metro?
For most offers the full metro (St Louis, St Louis County, St Charles, Chesterfield) works best. Splitting by postal code only matters for hyperlocal services.

How much should a small STL business spend monthly?
$700-$1,600 monthly is the comfortable range.

Does Cardinals season affect the auction?
Mildly — April through October sees slight engagement lifts around home game nights, but CPMs don't change much.

What ad format wins in St Louis in 2026?
Reels with authentic local cues (the Arch, Forest Park, Busch Stadium, The Hill) outperform generic Midwestern creative.

Should I include Illinois side of the river?
For ecommerce yes — Metro East adds cheap inventory. For local services, keep it tight to Missouri.

Is healthcare advertising worth running here?
Yes — St Louis's hospital cluster creates meaningful audience density for healthcare, wellness and medical education offers.
