McHenry County and the AI Answer Competition Index
AI Answer Competition Index
65.8/ 100
Ranked 342 among the 1,822 counties with 20,000 or more residents, and 219 within our own 400-market set. More established businesses per resident push the score up. How the score is built
Think of the index as a headcount of established competition, those with five or more employees, in eleven recommendation categories, for each 10,000 residents and compared across every county of 20,000 or more people. The categories are law, dental, medical, real estate, insurance, accounting, remodeling, plumbing and HVAC, roofing, electrical and auto repair. McHenry County scores 65.8, which is more crowded than most.
Look past the headline number and two features of McHenry County emerge: it is a county made up of many sizeable towns, and it is an affluent county. The measures below show where it stands against each other county.
- Change in the number of residents since the 2020 Census +0.8% Near the middle: 49th percentile
- What the middle household earns (2023 est.) $101,205 High end: 94th percentile
- Established competitors per 10,000 residents 13 Packed: 67th percentile
- Share of advice-led locations with 5+ employees 30.1% Slim slice: 19th percentile
- Larger firms: share of locations with 20+ employees 3.4% Large slice: 64th percentile
- Net change in advice-led locations, 2017 to 2022 +5% Near the middle: 54th percentile
- Named places above 2,500 residents 16 Many towns: 96th percentile
- Homes approved for construction in 2025, per 10,000 residents 48 Active permitting: 71st percentile
Percentiles compare McHenry County with all 1,822 counties of 20,000 or more residents: a percentile is the share of those counties with a lower value. Drawn from: Census population estimates, County Business Patterns for 2017 and 2022, income estimates from the Census Bureau and the Building Permits Survey.
The AI answer picture
McHenry County Is Many Local Questions, Not One
With 16 places above 2,500 residents (7 of them topping 10,000), McHenry County has more distinct towns than 96% of counties. Local questions usually name a town, so conversational, hyper-local content for each place you serve, backed by RankGuarantee™ landing pages, gives AI engines something specific to draw on for each one.
Two more details round out the picture. Median household income in McHenry County is $101,205, above 94% of counties. Only 30.1% of the advice-led locations in McHenry County have five or more employees, a lower share than in 81% of counties.
What this means for GEO services for McHenry County businesses: think town by town: each place deserves its own local content and consistent details.
Size matters for context: 312,800 residents put McHenry County 231st among 3,143 U.S. counties, and the population has changed +0.8% since the 2020 Census. All industries together have 8,082 employer locations, or 25.8 per 1,000 people.
Outside any named place (a city, town or census-designated place) live 62,307 of McHenry County's residents (20%), and their questions often skip the town name entirely and ask for something "near me" instead.
Where people live
McHenry County Place by Place: A Local Question for Each
These are the biggest places in McHenry County. Someone asking an assistant about a provider nearby will usually name one of them, which is why plans for answer engine optimization (AEO) in McHenry County start with the towns on this list.
| Place | Portion of the county | Residents in 2023 (estimate) |
|---|---|---|
| Crystal Lake | 13% | 40,861 |
| Lake in the Hills | 9% | 28,661 |
| McHenry | 9% | 28,251 |
| Woodstock | 8% | 25,699 |
| Huntley (part) | 7% | 22,477 |
| Algonquin (part) | 7% | 21,849 |
Population numbers come from Census Bureau estimates. A place can be a city, a town or a census-designated place, so a city split between counties is counted only where it lies in McHenry County.
Who else could be named
McHenry County Recommendation Categories, Ranked by Crowding
Each row is one of the eleven recommendation categories: established locations (five or more employees) in McHenry County, how that compares with the typical county, how the category as a whole has changed since 2017, and how many locations are large employers.
Kind of businessEstablished locations (5+ staff)Density vs. a typical countyAll-location change, 2017 to 2022Locations with 20 or more employees
Roofing contractorsMost crowded 11 +2.2% 0
Auto repair shops 47 -4.3% 3
Law offices 34 -4.7% 5
Plumbing and HVAC contractors 58 +8.3% 8
Dentists 89 -1.5% 6
Residential remodelers 19 +26.1% 3
Real estate agents and brokersGaining most 7 +57.7% 0
Physicians and medical practicesBiggest employers 72 -3% 15
Accountants and CPA firms 16 -12% 0
Electrical contractors 28 +1% 3
Insurance agenciesMost open 26 -9% 3
Bars give each category's established locations (five or more employees) per 10,000 residents as a multiple of the middle county among those ranked; the dark tick is 1.0x. Change is measured on all locations in the category, not just established ones. Counts come from County Business Patterns (2017, 2022) and are no measure of AI mentions or search volume. See the method
Roofing contractors are the most contested category in McHenry County: 11 established locations, 2.3 times the density of a typical county, with the category as a whole up 2.2% since 2017. A person asking an assistant which roofer to hire has the most names to sort through here. Denser than usual as well: auto repair shops (47 established locations, 1.8x) and law offices (34 established locations, 1.5x). Room exists in insurance agencies, where 26 established locations come to just 0.9x a typical county.
The fastest growth is in real estate agents and brokers: locations of every size rose 57.7% since 2017, to 112, so new names keep appearing. Accounting and CPA firms contracted by 12% since 2017, to 44 locations. The biggest employers sit in physicians offices, where 15 locations have 20 or more employees.
These figures describe the competition, not AI behavior. No public data tells us how often people ask an assistant for a recommendation or how an engine picks among businesses, and we do not guess; the table shows how many established rivals share the answer space.
Where demand is heading
McHenry County's Permit Count Is Flat Rather Than Spiking
Bars show new housing units approved by building permits. From the Building Permits Survey (Census Bureau): annual county data plus matching January-to-August totals. Approved units may not be built yet.
The annual count has stayed in a narrow band: 1,503 units in 2025 compared with 1,374 in 2021, or 48 per 10,000 residents, a rate above 71% of counties. Through the first eight months of 2026, 1,009 units were approved against 1,145 in the same months of 2025 (-11.9%).
Among businesses tied to building, roofing contractors (2.3x typical) and plumbing, heating and air-conditioning contractors (1.4x typical) are the most crowded in McHenry County. New households arrive without providers they trust, and a business whose details already match across the places AI engines read is easier for them to find described.

Questions we hear
McHenry County GEO: Frequently Asked Questions
How much does GEO cost in McHenry County?
GEO is not a standalone product: it comes with every Organic Growth plan. Silver is $1,495 a month, Gold is $2,495 and Platinum is $3,495, and Gold and Platinum add a fully managed, custom-built website. No setup fee, no contract.
Is GEO the same as AEO or AI search optimization?
Think of SEO as winning a place in a list of links and GEO as making your details usable to engines that answer directly. That covers Perplexity, ChatGPT and Google AI Overviews, and some people call it AEO. Because they share groundwork, we deliver both in Organic Growth.
How crowded are the recommendation categories in McHenry County?
According to the index, McHenry County is more crowded than most counties: it scores 65.8, which is 342nd out of 1,822 counties of 20,000 or more people and 219th of our 400 markets. The busiest category is roofing contractors, at 2.3x a typical county. A score is a headcount of established competitors, not a forecast of what any engine will do.
Do I have to sign a contract?
You can cancel anytime; there is no contract or setup fee. Each plan is billed month to month at a flat rate, and we take only one business per category per city.
What do you mean by consistent business details?
Your name, phone number and address, plus details such as hours and services, should be the same on Google, Apple Maps, Yelp and anywhere else an engine looks. The first step in our process is an audit of exactly that, since conflicting details make it harder for engines to describe you accurately.
Can GEO guarantee my McHenry County business shows up in AI answers?
It would be dishonest to promise an AI mention, so we do not. We aim for accurate, consistent information that matches wherever an engine looks. As engines gather, validate and favor consistent information, results improve over time, though we cannot say how long that takes. You see monthly test results from Google AI Overviews, ChatGPT and Perplexity.
Is GEO the same as advertising on ChatGPT?
Not at all. Advertisers can buy labeled, sponsored ads in ChatGPT through a self-serve Ads Manager, and some Free and lower-priced plan users see them. Measurement is still maturing, and the ads do not influence the answers. GEO is the unpaid work behind accurate answers about your business.
We have more than one location. Does GEO still work?
Yes, and multi-location businesses tend to benefit most, because AI tools need consistent, verified information to recommend a service locally. We begin by auditing every address so it is described identically wherever engines look. In McHenry County, 3.4% of advice-led locations have 20 or more employees.
Can the content cover every town in McHenry County that I serve?
Whichever places you work in. McHenry County has 16 places of 2,500 or more residents, led by Crystal Lake, Lake in the Hills, McHenry, Woodstock and Huntley. The GEO content is hyper-local, and RankGuarantee™ landing pages (25 a month on Silver, 50 on Gold and 100 on Platinum) create a page for each service in each place you cover.
