How Contested Are the Recommendation Categories in Cook County?
AI Answer Competition Index
64.5/ 100
Currently ranked 373 among the 1,822 counties of at least 20,000 people, and 234 within our own 400-market set. A higher number means a more crowded field of established competitors. See how it is calculated
The AI Answer Competition Index covers eleven kinds of business that people ask an assistant to recommend: law, dental, medical, real estate, insurance, accounting, remodeling, plumbing and HVAC, roofing, electrical and auto repair. For each county of 20,000 or more residents it counts established locations, those with five or more employees, per 10,000 people. Cook County scores 64.5, which is near the middle of the pack.
Cook County has two traits worth noting: it is a county where the headcount is flat or falling, and it is a county made up of many sizeable towns. The measures below show where it stands against each other county.
- Growth in headcount from the 2020 Census -3.6% Trails most: 4th percentile
- County median for household income (2023 est.) $80,547 Upper tier: 79th percentile
- Advice-led locations with 5+ staff per 10,000 people 12.7 Crowded: 65th percentile
- Share of advice-led locations with 5+ employees 28.9% Slim slice: 15th percentile
- Larger firms: share of locations with 20+ employees 6.2% Large slice: 84th percentile
- Advice-led locations added or lost, 2017 to 2022 -1.7% Below-average growth: 31st percentile
- Named places above 2,500 residents 113 Rich in places: 99th percentile
- Units cleared to build in 2025, per 10,000 residents 10.4 Quiet permitting: 20th percentile
A percentile here is the share of the 1,822 ranked counties (20,000 or more residents) that fall below Cook County's figure. Inputs: Census population estimates, the 2017 and 2022 County Business Patterns, income estimates from the Census Bureau and the Building Permits Survey.
What shapes AI visibility here
How a Shrinking Population Changes the GEO Math in Cook County
A shrinking population (-3.6% since the 2020 Census, 5,087,072 residents) means Cook County cannot count on newcomers to refill the customer base. Staying visible and accurate wherever people ask, including AI assistants, is how an established business holds on to its share.
Two other features of the Cook County market matter here. Cook County has 113 communities above 2,500 residents, 79 of them above 10,000, more than 99% of counties. Only 28.9% of the advice-led locations in Cook County have five or more employees, a lower share than in 86% of counties.
When it comes to GEO services for Cook County businesses, a shrinking market makes every customer count, and being described correctly is part of keeping them.
Chicago holds about 52% of Cook County's residents, so it matters most, but the rest of the county (Cicero, Schaumburg and Evanston) asks about its own town names, and each one is a separate local answer.
Demand signal
Building in Cook County Is Below Its 2022 High and Still Slowing This Year
Bars show new housing units approved by building permits. Data: Building Permits Survey, county annual files, and a like-for-like year-to-date comparison. Permits mark intent to build, not finished construction.
Permits peaked at 8,325 units in 2022 and came in at 5,308 in 2025, roughly 36% lower. Even so, 2025 equals 10.4 units for every 10,000 residents, which is below 80% of counties. Through the first eight months of 2026, 3,204 units were approved against 3,884 in the same months of 2025 (-17.5%).
Among businesses tied to building, real estate agents and brokers (2.4x typical) and insurance agencies (1.2x typical) are the most crowded in Cook County. Rising permits bring people who need a roofer or an electrician and have no one to ask, and falling permits shift questions toward repair and replacement. Either way, accurate local information is what GEO works on.

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 covers every employer location in the category, of any size. Source: Census County Business Patterns (2017, 2022), which says nothing about AI behavior or search volume. See the method
The busiest category in Cook County is law offices, with 1,153 established locations at 3.1x the density of a typical county, with the category as a whole down 6.8% since 2017. More comparable names means more weight on the details that tell them apart. The next busiest categories are real estate agents and brokers (257 established locations, 2.4x) and dentists (1,369 established locations, 1.3x). The lightest field belongs to electrical contractors: 324 established locations, 0.7x the typical density, so an answer in that category has fewer names to weigh.
The fastest growth is in real estate agents and brokers: locations of every size rose 14.8% since 2017, to 2,478, so new names keep appearing. Physicians offices shrank instead, losing 15% of their locations to land at 2,849. The biggest employers sit in physicians offices, where 393 locations have 20 or more employees.
Remember what a count can and cannot say. It tells you how many established businesses are in each category. It says nothing about AI mentions, search volume or timing, and nobody can promise a mention in an AI answer.

Questions we hear
Your Questions About GEO in Cook County, Answered
What does AI search optimization cost for businesses in Cook County?
Pricing is flat and monthly, and GEO is part of the Organic Growth plans rather than as a separate line item: $1,495 for Silver, $2,495 for Gold and $3,495 for Platinum. If you only want local landing pages, RankGuarantee™ is $495 a month alone and comes with each plan. Cancel anytime: there is no contract and no setup fee.
Is there a timeline for GEO results in Cook County?
Engines set the pace, so we give no timeframe. The work follows a set order: audit, schema, content, and each month after that we check Google AI Overviews, Perplexity and ChatGPT and change course where needed. Crowding in law offices across Cook County is a reason for care, not a forecast.
Is GEO the same as AEO or AI search optimization?
GEO stands for generative engine optimization: preparing your online presence for AI engines such as Perplexity, Google AI Overviews and ChatGPT. Others use the term AEO, or answer engine optimization. They answer directly instead of listing links, drawing on structured data, business listings and trusted content. GEO is the next step beyond SEO and complements it; it does not replace it.
How does Cook County compare with other markets on AI answer competition?
About average. Cook County scores 64.5 on our AI Answer Competition Index, sitting at 373rd among the 1,822 counties we rank, and 234th within our 400-market set. Law offices lead the field for crowding, at 3.1 times the typical county. The index counts established businesses, not AI behavior.
Are ChatGPT ads part of GEO?
They are two separate things. Advertisers can buy labeled, sponsored ads in ChatGPT through a self-serve Ads Manager, and some Free and lower-priced plan users see them. The ads do not affect the answers, and measuring them is still maturing. GEO is the unpaid work behind accurate answers about your business.
Do I need a new website to start GEO?
You do not have to. It begins with the audit, moves to schema on key pages and then to local content. A new site is an option, not a requirement: Gold and Platinum come with a custom-built, fully managed website if you want one.
What do I actually get with GEO?
The work covers structured data on your key pages (Review, LocalBusiness and FAQ schema), consistent business details across Google, Apple Maps, Yelp and more, conversational hyper-local content, review and reputation work, technical SEO, and ongoing monitoring across Google AI Overviews, ChatGPT and Perplexity. Reports cover citations, AI visibility, knowledge panels, platform traffic and local rankings.
Can GEO guarantee my Cook County business shows up in AI answers?
We do not promise AI mentions, because nobody controls them. 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.
Does GEO help businesses with several locations?
It is especially useful for several locations. AI tools need consistent, verified data to recommend a business locally, so a name, address, phone number and set of hours that match across Google, Apple Maps, Yelp and the rest matter at every location. Larger firms, with 20 or more employees, hold 6.2% of the advice-led locations in Cook County.
