The AI Visibility Gap
Only 11% of Illinois electricians have JSON-LD structured data on their websites. That single metric explains more about AI search performance than almost any other signal.
JSON-LD is the markup language that tells AI recommendation engines what a business does, where it operates, and why it should be trusted. Without it, ChatGPT, Perplexity, and Google AI Overviews have no machine-readable signal to pull from. A contractor with 200 five-star reviews and a polished website can still be functionally invisible if the data isn't structured for AI consumption.
Across 660 electricians tracked in Illinois, the average AI Trust Score sits at 37.2/100. The score is built from three components: Identity (25 points: name, address, and phone consistency), Legitimacy (35 points: reviews, ratings, license and insurance verification), and Readability (40 points: website quality, JSON-LD structured data, mobile-friendliness). At 37.2, the average Illinois electrician is underperforming on all three.
The tier distribution confirms the problem. Only 0.8% of contractors reach the Excellent tier (80-100). In raw numbers, that's 4 contractors scoring in the 80-89 range. None score 90 or above. At the other end, 12.1% score below 40, meaning roughly 80 contractors are generating almost no useful AI signal at all.
The review picture is equally stark. The median review count for Illinois electricians is 0.0. More than half of all tracked contractors have zero reviews feeding into the Legitimacy scoring component. AI assistants weight review volume and recency heavily when surfacing local service recommendations. A business with no reviews doesn't just score poorly on Legitimacy: it doesn't register at all.
Illinois is ahead of most tracked markets on JSON-LD adoption. The national average across 66 tracked states and regions is 1.2%. At 11%, Illinois electricians are nearly 10 times that rate. But that comparison flatters the state more than it should. 89% of Illinois electricians still lack structured data entirely, which means the large majority remain invisible to AI recommendation layers regardless of their website quality.
Website presence isn't the issue. 100% of tracked Illinois electricians have a website, compared to a national average of just 16.2%. The infrastructure exists. The structured signals don't.
That gap is the core problem. A website without JSON-LD is a billboard facing the wrong direction: visible to humans who already know where to look, invisible to the AI systems increasingly responsible for sending them there in the first place.

What AI Models Check
AI recommendation engines don't read your website the way a homeowner does. They parse structured signals across three specific categories, each carrying a defined point weight. Understanding how those categories break down explains why a 37.2 average score translates directly into missed leads.
Identity: 25 points
Identity covers NAP consistency: whether your business name, address, and phone number match exactly across your website, Google Business Profile, and third-party directories. A single inconsistency (a suite number on one listing, missing on another) introduces ambiguity that AI models resolve by deprioritizing the business. Google Business Profile completeness factors here too: hours, service categories, and photos all contribute to the signal.
Legitimacy: 35 points
Legitimacy pulls from review volume, star ratings, and license and insurance verification. For Illinois electricians, the rating picture is genuinely strong: the average across 660 tracked contractors is 4.67 stars. That's a healthy signal.
The review count tells a different story. The average is 28.0 reviews, but that number is pulled upward by a small group of high-performers. The median is 0.0. More than half of tracked Illinois electricians have no reviews contributing to their Legitimacy score at all.
The gap between top and bottom performers makes this concrete:
| Segment | Avg Score | Avg Reviews |
|---|---|---|
| Top 10% | 64.8/100 | 44.0 |
| Bottom 50% | 29.1/100 | 3.0 |
Top performers have 17.7x more reviews than the bottom half. That disparity doesn't just affect Legitimacy: it compounds across all three categories, because AI models use review signals as a proxy for business activity and trustworthiness when other data is thin.
Readability: 40 points
Readability carries the most weight in the scoring model, and it's the category where Illinois electricians lose the most ground. Website quality, mobile-friendliness, and JSON-LD structured data determine whether AI systems can actually parse what you do and where you do it.
Only 11% of Illinois electricians have JSON-LD structured data on their websites. That means 89% of tracked contractors are asking AI recommendation engines to infer their business information rather than read it directly. Inference is unreliable. Structured data is not.
Within the electrician vertical, Illinois actually leads comparable trades: electricians in the state post an average score of 51.0/100, versus 37.5 for plumbers and 30.5 for general contractors. JSON-LD adoption among Illinois electricians sits at 33%, compared to 0% for plumbers and 0% for general contractors in the same state. The gap within the vertical is real, but the baseline remains low.
The 40-point weight on Readability reflects how AI systems work. Identity and Legitimacy matter, but if the machine can't read your website structure, the other signals don't get processed consistently. Readability is the prerequisite.

Score Distribution: Where 660 Illinois Electricians Actually Land
The distribution below shows exactly where Illinois electricians cluster. The concentration in the middle bands tells the structural story.
| Score Range | Contractors | Share |
|---|---|---|
| 10-19 | 5 | 1% |
| 20-29 | 133 | 20% |
| 30-39 | 310 | 47% |
| 40-49 | 123 | 19% |
| 50-59 | 35 | 5% |
| 60-69 | 44 | 7% |
| 70-79 | 6 | 1% |
| 80-89 | 4 | 1% |
| 90-100 | 0 | 0% |
The dominant band is 30-39. Nearly half of all tracked contractors (310, or 47%) land here. These businesses have a functional web presence and some review activity, but are generating weak structured signals across all three scoring categories. They're not failing outright: they're stuck in a zone that AI recommendation engines treat as low-confidence.
Combine the below-40 group (12.1%) with the Fair tier (40-59, which accounts for 75.6% of contractors) and the picture sharpens. The overwhelming majority of Illinois electricians are underperforming on AI visibility. Only 12.3% score above 60.
The top of the distribution is thin. Four contractors score in the 80-89 range. None score 90 or above.
How Illinois Electricians Compare to Other Verticals
Within Illinois, electricians lead every tracked vertical by average score. The cross-vertical comparison makes the gap visible:
| Vertical | Avg Score | JSON-LD Adoption |
|---|---|---|
| Electricians | 51.0 | 33% |
| Landscapers | 42.5 | 0% |
| Plumbers | 37.5 | 0% |
| Roofers | 37.4 | 4% |
| General Contractors | 30.5 | 0% |
The 33% JSON-LD adoption rate among Illinois electricians is the single biggest reason for that lead. Plumbers, landscapers, and general contractors are at 0%. Roofers reach 4%. Electricians are structuring their data at a rate no other Illinois vertical comes close to matching.
That relative advantage is real. It doesn't change the fact that 67% of Illinois electricians still lack JSON-LD entirely, leaving Readability (the 40-point category) as the weakest scoring component across the vertical.
How Illinois Stacks Up Against Neighboring Markets
Illinois electricians (avg 51.0) outperform every neighboring tracked state and province:
- New York: 40.1/100
- Ontario: 39.6/100
- Pennsylvania: 38.6/100
The margin is meaningful, not marginal. Illinois electricians score nearly 11 points above New York and nearly 13 points above Pennsylvania. JSON-LD adoption explains much of that gap: New York sits at 14% overall across all verticals, Pennsylvania at 14%, while Illinois electricians specifically reach 33%.
The broader Illinois state average across all verticals is 37.2/100, which means electricians (at 51.0) are pulling significantly above the statewide baseline. The Illinois State Market Report breaks down how every vertical in the state compares.
What the Distribution Signals
The 30-39 cluster isn't random. It reflects a specific structural pattern: contractors with websites (100% have them), moderate or no reviews, and no structured data markup. They've built the foundation but left the machine-readable layer empty.
Readability carries 40 points in the scoring model. With 89% of Illinois electricians lacking JSON-LD, most businesses are leaving the highest-weighted category significantly underscored regardless of how strong their Identity or Legitimacy signals are.
The path from the 30-39 band to the 60+ tier runs directly through Readability improvements: JSON-LD implementation, mobile optimization, and structured site architecture. Identity and Legitimacy gaps matter, but they're secondary to fixing the structured data problem first.

Action Steps: Where to Start and What Each Fix Is Worth
Fixing AI visibility is a sequencing problem. The three scoring categories carry different point weights, and the gaps in each are different sizes. Work highest-weight to lowest.
---
1. Readability: Up to 40 Points
Readability is the highest-weighted category and the one with the most recoverable ground.
Add JSON-LD structured data. 67% of Illinois electricians still lack it. JSON-LD is a block of code that sits in your website's header and tells AI systems: this is the business name, this is the service area, this is the license number, these are the hours. AI engines don't infer that information reliably from prose. They read structured data directly. Without it, the 40-point Readability category scores near its floor regardless of how polished the site looks.
This is a one-time implementation. A developer can add it in under an hour. The point recovery potential is higher here than anywhere else in the scoring model.
Optimize for mobile. Google's indexing is mobile-first. AI systems that pull from Google's index inherit that weighting. A site that renders poorly on a phone is losing Readability points even if the desktop version is clean.
Address page speed. Slow load times signal low site quality to both Google and AI recommendation layers. Compress images, eliminate unused scripts, and use a content delivery network if your hosting plan supports it.
---
2. Legitimacy: Up to 35 Points
The median review count for Illinois electricians is 0.0. The bottom 50% average 3.0 reviews. The top 10% average 44.0 reviews and score 64.8/100. The bottom 50% score 29.1/100. That 35.7-point gap in scores tracks almost exactly with the review gap.
Build review volume systematically. Moving from 3 reviews to 44 is achievable over 12 to 18 months with a consistent ask-after-job-completion process. Text-based review requests sent within 24 hours of job completion outperform email follow-ups significantly. Each incremental review moves the Legitimacy score upward, and AI systems weight recency: recent reviews matter more than old ones.
Verify licenses and insurance publicly. Legitimacy scoring pulls from verifiable credentials. If your license number isn't published on your website and matched against state records, that portion of the 35-point category scores zero. Illinois requires electricians to hold state licensure: make that number findable.
---
3. Identity: Up to 25 Points
Identity is the lowest-weighted category but the easiest to fix completely.
Audit NAP consistency. Your business name, address, and phone number must match exactly across your Google Business Profile, your website footer, and every directory listing. Abbreviations count. "St." versus "Street" introduces a mismatch. Run a manual check across Google, Yelp, Angi, and any trade directories where you're listed.
Complete your Google Business Profile. Service categories, hours, and photos all contribute to the Identity signal that AI systems pull when resolving local queries.

Frequently Asked Questions
What is the average AI Trust Score for electricians in Illinois?
The average AI Trust Score across 660 tracked Illinois electricians is 37.2/100. That score reflects performance across three categories: Identity (25 points), Legitimacy (35 points), and Readability (40 points). At 37.2, the average contractor is underperforming in all three. Only 0.8% of Illinois electricians reach the Excellent tier (80-100). Check where your business falls at /find.
What is JSON-LD and why does it matter for electricians?
JSON-LD is structured data markup that tells AI recommendation engines your business name, service area, hours, and license information in machine-readable format. Without it, systems like ChatGPT and Google AI Overviews have to infer that information from unstructured text, which is unreliable. Only 33% of Illinois electricians have JSON-LD implemented. The other 67% are leaving the 40-point Readability category significantly underscored regardless of website quality.
How do reviews affect AI visibility for electrical contractors?
Reviews feed directly into the Legitimacy category, which carries 35 points. The median review count for Illinois electricians is 0.0, meaning more than half of tracked contractors have no reviews contributing to their score. The top 10% of performers average 44.0 reviews and score 64.8/100. The bottom 50% average 3.0 reviews and score 29.1/100. That 17.7x review gap between those groups drives most of the scoring disparity in the vertical.
How do Illinois electricians compare to other trades in the state?
Illinois electricians average 51.0/100, the highest of any tracked vertical in the state. Landscapers average 42.5, plumbers 37.5, roofers 37.4, and general contractors 30.5. The 33% JSON-LD adoption rate among electricians explains most of that lead: every other Illinois vertical sits at 4% or below. The full vertical breakdown is in the Illinois State Market Report.
