Reach profile
Inside the 47.4: How St. Clair County Compares
Local Online Reach Index
47.4/ 100
Sits at 901 among 1,822 counties that clear 20,000 residents, and 376 among the 400 markets on this site. Higher means more businesses to compete with and more towns and households to reach. How the score is made
Think of the Local Online Reach Index (LORI) as a measure of the territory a marketing plan has to cover. Six public Census measures feed the 0 to 100 score: rivals, new openings, towns of 2,500 or more, household income, dispersion of residents and headcount. St. Clair County lands at 47.4, which is about average nationally.
Two features stand out in St. Clair County: it is a county whose population is flat or shrinking, and it is a county with many towns of real size. The bars place each measure among all of those counties.
- Headcount change from 2020 -2.5% Behind the pack: 8th percentile
- What the middle household brings in (2023 est.) $66,007 Near the middle: 49th percentile
- Employer locations for every 1,000 residents 20 Roomy: 38th percentile
- Employer locations opened net of closings, 2017 to 2022 -4.1% Behind the pack: 9th percentile
- Named towns above 2,500 people 15 Many towns: 96th percentile
- Residents living outside any named place 20% Town-centered: 11th percentile
- Permitted housing units in 2025, per 10,000 residents 17.2 Few new homes: 32nd percentile
- Share of tiny employer locations (under 5 employees) 56.3% Low share: 37th percentile
Bars show where St. Clair County stands among 1,822 counties that clear 20,000 residents, as the portion of them with a smaller value. Figures draw on business counts in County Business Patterns, 2017 and 2022, the 2023 Census population estimates, plus SAIPE income estimates for 2023, with the Building Permits Survey for new homes.
The business count
St. Clair County Has Changed Little Since 2017, and That Shapes the Plan
St. Clair County is a settled market. Employer locations went from 5,243 to 5,030 (-4.1%), slower than in 91% of counties, so a business there is mostly up against familiar competitors instead of a wave of new ones.
Headcount has fallen 2.5% since 2020, behind 92% of counties. It is also town-rich, with 15 places over 2,500 people, more than 96% of counties. What does it mean for digital marketing in St. Clair County? In the ranking further down, Local SEO landing pages (RankGuarantee™) and Google Maps and your Business Profile come out ahead of the other five channels.
By the raw numbers: 5,030 employer locations employing 71,616 people, 20 locations per 1,000 residents, and 251,018 residents overall (288th of 3,143 counties), with a median household income of $66,007.
In St. Clair County, 20% of residents (50,146 people) live outside the named places. When they look for a business they tend to search by the county or by "near me", not by a town.
Anyone comparing an internet marketing company in St. Clair County should ask how it would split work across channels for a market that shows a 4.1% drop in employer locations since 2017; the table further down shows how GetPhound would read the same data.
Where to start
Digital Marketing for St. Clair County Small Businesses: Seven Channels, Ranked by Local Data
The order below comes from St. Clair County's own percentiles, one set of measures per channel, which is why two counties rarely get the same list.
| Where it ranks | Where it sits | Reading of St. Clair County's data |
|---|---|---|
| 1. Local SEO landing pages (RankGuarantee™) | Start here | With 15 towns over 2,500 people, pages are written per service per town. Gold's 50 a month averages 3.3 for each town. |
| 2. Google Maps and your Business Profile | First move | 409 trade, repair, cleaning and landscaping locations (16.3 per 10,000 residents), lighter than most counties, so a complete Business Profile can stand out. |
| 3. Bing search ads | Second wave | Median household income of $66,007 is below 51% of counties. Bing's audience skews higher-income, so it is a smaller bet here; adding it to Google moves Paid Ads to $1,595 a month. |
| 4. AI search (GEO) | Second wave | 514 law, dental, medical, real estate, insurance and accounting locations (20.5 per 10,000 residents), categories people put to assistants. GEO is in every Organic Growth plan. |
| 5. Custom WordPress website | Add next | 56.3% of employer locations have under five staff and the count has moved -4.1% since 2017, so the website question is usually a refresh, not a first build. A rebuild is optional; Gold and Platinum include one. |
| 6. Meta Ads on Facebook and Instagram | Later, if needed | 251,018 residents and 7.6 restaurants and salons per 10,000. Meta targets by location (including a radius around the business), age and interests. Three platforms total $2,295 a month. |
| 7. Google Ads | Not first | 5,030 employer locations, -4.1% since 2017: a quieter field, so ads can wait until the organic groundwork is set. A single platform costs $895 a month when it is needed. |
The order is a judgment from Census figures, not a prediction; plan prices come from getphound.com/pricing. Method
Pages come first. With 15 places above 2,500 residents, from Belleville down to the smallest town, St. Clair County gives landing pages the most room to work, and the entry point is RankGuarantee™ at $495 a month. Google Maps and your Business Profile still tops the list, largely since the other channels stand out less in St. Clair County. 409 trade, repair, cleaning and landscaping locations (16.3 per 10,000 residents), lighter than most counties, so a complete Business Profile can stand out.
Bing fits the second wave at $66,007 household income; two platforms are $1,595 a month. GEO is the second wave, and it comes with every Organic Growth plan at no separate price. A custom website joins next: standalone it is typically $3,500, and Gold and Platinum include one. Facebook and Instagram come later here, even with an audience of 251,018. Google Ads is not the first need with 5,030 employer locations and slow change.
None of this predicts leads, rankings or timing; it is a reading of public data to decide where internet marketing in St. Clair County should begin.
Towns and cities
Largest Places in St. Clair County and Their Share of the County
The biggest places in St. Clair County by resident count. Customers name their town when they search, so each row is a separate audience for local pages, listings and ads.
| # | Place | Residents, 2023 est. | Of the county total |
|---|---|---|---|
| 1 | Belleville | 40,726 | 16% |
| 2 | O'Fallon | 31,968 | 13% |
| 3 | East St. Louis | 17,642 | 7% |
| 4 | Cahokia Heights | 17,114 | 7% |
| 5 | Fairview Heights | 16,125 | 6% |
| 6 | Shiloh | 14,736 | 6% |
Residents per the Census Bureau's estimates; a place can be a city, a town or a census-designated place, so a city shared with another county is listed for its St. Clair County side alone.
No single place dominates: the largest, Belleville, holds 16% of St. Clair County's residents, and 15 places pass 2,500 (7 pass 10,000). Coverage means many smaller audiences instead of one big one.

| 15 | Roofers | 18 | 0.7 (1.2x) | +28.6% |
Fifteen categories, most numerous first. The multiple in brackets divides St. Clair County's locations per 10,000 residents by the median county's figure, so anything under 1.0x is lighter than typical. Source: County Business Patterns for 2017 and 2022, which leaves out one-person businesses with no employees. About these figures
By headcount of locations, restaurants (158), physician practices (128) and law firms (123) lead the list. Crowding stands out in law firms (1.7x the typical county) and cleaning firms (1.4x the typical county). The thinnest field is plumbing and HVAC firms, at 0.7x the typical county. New names keep appearing among real estate offices, up 16.3% since 2017. Restaurants went the other way, down 4.2% since 2017.
New construction
St. Clair County Is Building Less Than at Its 2022 Peak
The figures are housing units authorized for construction. Data: the Building Permits Survey; the last two bars compare matching January to August totals. Not each permit ends in a finished home.
Permits peaked at 852 units in 2022 and came in at 433 in 2025, 49% lower. Even so, that is 17.2 units per 10,000 residents. Through August 2026, 301 units were approved against 358 a year earlier (-15.9%).

Should the website come before ads and local pages in St. Clair County?

Does Bing Ads make sense in St. Clair County?
GetPhound's Bing Ads page describes the audience as older, higher-income and desktop-heavy. St. Clair County has a median household income of $66,007, lower than 51% of counties, so Bing is a secondary add-on. Google and Bing together are $1,595 a month on the Paid Ads plan.

Local SEO landing pages (RankGuarantee™) first, then Google Maps and your Business Profile, then Bing search ads. The order comes from St. Clair County's own percentiles (a 4.1% drop in employer locations since 2017), and a business with a different customer mix may reasonably reorder it.
Are ChatGPT ads worth a test in St. Clair County?
Treat ChatGPT ads as an experiment. The placements are sponsored and labeled, appear for a share of users on Free and cheaper plans, and are bought through a self-serve Ads Manager with country or context targeting; measurement is still maturing. In St. Clair County, where 20.5 advice-led locations compete per 10,000 residents, the unpaid GEO work in Organic Growth comes first.
How many other businesses does a company in St. Clair County compete with?
St. Clair County has 5,030 employer locations, 20 for every 1,000 residents, ahead of 38% of counties for density. The most numerous groups are restaurants (158), physician practices (128) and law firms (123). These counts leave out sole proprietors without employees, so the true field is larger.
