The editor's read
A Writing Plan Built Around St. Charles County's Numbers
Money is part of the picture in St. Charles County: a $98,765 median household income puts it ahead of 93% of counties. Bigger purchases get longer deliberation, so depth, specifics and plain explanations of how a business works matter more than short announcements.
Beyond that, two details matter. 9 towns top 2,500 residents, higher than in 92% of counties. 70.4% of research-heavy locations have fewer than five employees, above 75% of counties. The first pieces should be thorough comparisons, not announcements.
For scale, 416,659 residents make St. Charles County the 178th largest of 3,143 counties, with 8,974 employer locations (215.4 per 1,000 residents) providing 142,108 jobs. The median household earns $98,765, more than 95% of counties. One more group is easy to miss: 93,218 residents, 22% of the county, live outside any named place and tend to search by road or neighborhood, not by town.
Page math
What Each Plan Would Cover in St. Charles County
Assume a St. Charles County business offers three services and wants a page for each in every one of the 9 places above 2,500 residents: that makes 27 pages. Each plan's build time for that grid is in the table.
| Plan level | Per month | Landing pages each month | Months to cover every town | Assets written over a year |
|---|---|---|---|---|
| Silver | $1,495 | 25 | 1.1 months | 48 (5.3 per place) |
| Gold | $2,495 | 50 | 0.5 months | 96 (10.7 per place) |
| Platinum | $3,495 | 100 | 0.3 months | 144 (16.0 per place) |
Three services per large place is an assumption. Plan volumes match the pricing page.
Treat the grid as a sizing exercise; nothing here predicts leads or rankings. Written assets come on top.
The field
The Research-Heavy Field in St. Charles County, Category by Category
1,113 employer locations ordered by density next to the median county. The last column counts teams under five employees, the ones with the least time to spare.
Bar length is locations per 10,000 residents relative to the median county; the tick marks 1.0x. From County Business Patterns, 2017 to 2022, which counts businesses and nothing online. See the method
The busiest category is real estate agents and brokers, with 198 locations at 1.9 times the median county's density (up 53.5% since 2017). A buyer looking here wants to understand what inspections turn up, how the closing steps run and how offers and counteroffers work. It grew faster than any other category too. Residential remodelers follow at 1.5x the typical county.
Only dentists and accounting and CPA firms shrank. Small teams are most common among real estate agents and brokers: 183 of 198 locations have fewer than five employees. Across all seven categories it is 784 of 1,113.
These figures count businesses, and nothing about who publishes, so read it as context, not prediction.
