Missouri has two large metros at opposite ends of the state, and both of them cross or sit against state lines. That produces a targeting problem that catches out a lot of accounts.
Nobody realistically serves both Kansas City and St. Louis. And in each of them, the metro definition includes territory in another state that you may or may not cover.
Targeting by metro name is the trap
Selecting "Kansas City" in an ad platform includes the Kansas side. Selecting "St. Louis" includes the Illinois side. If your crews do not cross, you are paying for clicks that cannot become jobs — and because those leads look identical in the report, nobody notices.
The fix is drawing targeting around your actual service area rather than accepting a metro definition. It sounds obvious. It is one of the most common sources of waste we find in Missouri accounts.
Two metros, two plans
They differ on competition, cost, and household profile. Running them as one statewide campaign means a shared budget and shared bids across markets four hours apart, which serves neither.
If you genuinely operate in both, they should be two accounts' worth of separation: separate campaigns, budgets, landing pages, and reporting.
Severe weather is the recurring event
Missouri sits in an active corridor for hail and wind. Those events produce short windows of enormous demand for roofing and exterior trades, and they go to whoever is already live.
The readiness is the same as anywhere it matters: campaigns created and paused, landing pages built, budget agreed, copy approved. One decision on the day rather than a build.
Knowing your capacity beforehand matters too. Generating more storm demand than you can service produces the reviews that outlast the revenue.
Springfield and Columbia are their own markets
Considerably lighter auctions than either metro, with less competition and lower click costs. If you serve them, they deserve their own campaigns rather than being funded from a metro budget where the higher metro bids set the pace.
They are also markets where consistent local SEO moves position faster than it will in Kansas City or St. Louis, which changes where the first money should go.
The follow-up point that applies everywhere
Whatever the geography, most Missouri accounts we audit are losing more to slow follow-up than to targeting. Speed to first contact and the share of quotes that never got a second touch are usually more actionable than any bid change.
Fix that first. It costs almost nothing and it makes every subsequent media decision more efficient.
