Sangamon County's Ad Competition Index Score and What Sits Behind It
Ad Competition Index
60.4/ 100
Rank 497 of 1,822 counties with 20,000+ residents and also 207 of the 400 markets we cover. A higher score means more local businesses are competing for the same searches. See the method
We rate every U.S. county-equivalent with 20,000 or more residents on how many ad-heavy local businesses (including lawyers, dentists, contractors, agents and similar) are chasing the same residents. Sangamon County scores 60.4, which is close to the middle of the pack.
Two things stand out: Sangamon County is a county whose population is flat or shrinking, and it is also a county with an unusually high share of bigger (20+ employee) businesses in ad-heavy categories. The eight measures that follow place it among every other county.

Local context
How a Slow-Growth Market Changes Your Google Ads Plan in Sangamon County
Sangamon County has slipped 1.5% in population since the 2020 Census, a weaker trend than 84% of comparable counties, and now has 193,491 residents. In a market without a steady stream of newcomers, growth has to come from winning customers who already have a provider, which puts more weight on your offer, your reviews and your landing page.
The biggest places in Sangamon County are Springfield (112,544), Chatham (14,525), Sherman (4,599), Auburn (4,444) and Rochester (3,899). Targeting can follow cities, ZIP codes or a radius around your location, so clicks stay on the side of the county you actually serve.
31,365 people, or 16% of residents, live outside any incorporated place. Radius and ZIP targeting reach them where city-only targeting would not.

Sangamon County Housing Permits Since 2021: Down From the High, Turning Up This Year
New homes authorized by building permits. Data: the Census Bureau's Building Permits Survey (county annual files; year-to-date comparison covers the same months in each year). A permit is an authorization, not a finished home.
Sangamon County authorized 317 housing units in 2021 and 221 in 2025, about 30% fewer; 2025 still works out to 11.4 units per 10,000 residents, less than in 78% of counties. For January through August, permits are running at 155 against 120 a year earlier (+29.2%).
In Sangamon County, the construction-linked categories already busiest are insurance agencies and brokerages (1.5x typical) and real estate agents and brokers (1.3x typical). People moving into new homes need contractors, insurers, agents and providers, so categories tied to construction feel a swing in permits first. If you work in that space, a turn in permits is a reason to review your budget before the busy stretch, not after.

Crowding is employer locations per 10,000 residents relative to the median U.S. county of 20,000+ residents (1.0x is typical; the dark tick marks it). Counts are establishments from County Business Patterns (2017, 2022), not a count of active advertisers. See the method
In Sangamon County, the law offices category is the most crowded, with 85 locations at 1.5 times the typical density; the count is down 7.6% since 2017. Insurance agencies and brokerages (106 locations, 1.5x) and dentists (82 locations, 1.5x) also sit above a normal county. At the other end, the residential remodelers category (52 locations) is below typical density at 0.9x, which can mean more room to win a strong position.
Real estate agents and brokers grew fastest, up 39.1% since 2017 to 64 locations. Physicians offices went the other way, down 20.8% to 84 locations. The biggest operators sit in physicians offices: 23 of 84 locations have 20 or more employees.
Remember that this is a headcount of businesses, not a price list. An auction decides what a click costs, and it weighs far more than the number of competitors, so we build around your keywords, offer and landing page instead of the headcount.

The densest category here is
About average. Sangamon County scores 60.4 on our Ad Competition Index, ranking 497th of 1,822 counties with 20,000+ residents and 207th of the 400 markets we cover. Law offices, at 1.5 times the typical county. That rewards consistency: consistent campaigns can take positions that would be fought over in a larger market.

Across the twelve ad-heavy categories we track, the largest by employer locations in Sangamon County are insurance agencies and brokerages (106), law offices (85) and physicians offices (84). Measured against a typical county, the most crowded are law offices (1.5x) and insurance agencies and brokerages (1.5x). A large or crowded category does not settle whether ads will work for you; it only shows how many other businesses could be bidding on the same searches.
How soon will I get calls from Google Ads in Sangamon County?
It varies. A few accounts get calls on day one; the rest need two to four weeks of tuning, more so in busy categories like law offices. We check the searches that triggered your ads early and exclude those that do not suit your business.
Is Sangamon County growing, and does that matter for Google Ads?
Sangamon County has 193,491 residents, −1.5% since the 2020 Census, and 221 housing units were permitted in 2025 (11.4 per 10,000 residents). When the population is slipping, new customers mostly have to come from competitors. Whichever way it goes, ads reach the people who are searching today, and that is why these trends inform the budgets we set.
Can you target only the parts of Sangamon County I serve?
Yes. We can target by city (Springfield, Chatham, Sherman, Auburn and others), by ZIP code or by a radius around your location. Around 16% of residents live outside any incorporated place, which is where radius targeting helps.
Can you run Facebook, Instagram and Bing ads too?
Yes, we do. Beyond Google Ads, we manage Bing ads and Meta ads, which run on Facebook and Instagram. Google tends to be the first platform since searchers are ready to act; Bing adds a second search audience, and Facebook and Instagram reach people before they search. The fee depends on how many platforms you run: $895, $1,595 or $2,295 a month.
Do I have to sign a contract, and how will I know it is working?
You can cancel anytime, because there is no contract. A dedicated account manager handles your campaign and sends monthly reports on the calls, forms and sales.
