The AI Visibility Gap
Of the 388 general contractors tracked in Ohio, exactly 0% have implemented JSON-LD structured data. Every single one has a website. None of those websites speak the language that AI recommendation engines actually read.
That gap explains most of the problem. When ChatGPT, Gemini, or Perplexity fields a query like "best general contractor in Columbus," they pull from structured signals: schema markup, verified identity data, consistent NAP (name, address, phone) records, and review signals. Ohio general contractors produce almost none of those signals.
The numbers confirm it. Ohio general contractors average 36.5/100 on the AI Trust Score, fractionally below the state average of 37.2/100 across all verticals. The median score sits at 35.0/100. Half the state's general contractors score below that line. Only 0.5% reach the Excellent tier (80-100). General contractors are the single lagging vertical in Ohio, with 0% in the Excellent tier.
The AI Trust Score breaks into three weighted categories:
- Identity (25 pts): Business name, address, and phone consistency across directories
- Legitimacy (35 pts): Review volume, ratings, license and insurance verification
- Readability (40 pts): Website quality, JSON-LD structured data, mobile-friendliness
Readability carries the heaviest weight, and it's where Ohio general contractors lose the most ground. A website that exists but contains no structured markup is effectively invisible to AI parsing tools. You have a digital presence. You don't have a machine-readable one.
The score distribution makes the scale of the problem concrete:
| Score Range | Contractors | Share |
|---|---|---|
| 80-100 (Excellent) | ~2 | 0.5% |
| 60-79 (Good) | ~50 | 12.9% |
| 40-59 (Fair) | ~288 | 74.2% |
| Below 40 | ~48 | 12.4% |
The "Fair" tier is misleading. A score in the 40-59 range still means AI tools are likely skipping you in favor of competitors who have closed the structured data gap.
Ohio is not uniquely behind. In national context, the state's 37.2 average across all verticals outperforms Florida (15.2/100), California (20.2/100), and Texas (30.3/100). But it trails New York (40.1/100) and Alberta (41.7/100), two markets where JSON-LD adoption and profile verification are measurably higher.
The implication: Ohio general contractors are average performers in a low-performing field. That's not a safe position. As AI-driven referrals grow, average visibility produces below-average outcomes.

What AI Models Actually Check
The AI Trust Score is built from three categories. Understanding the weight of each one tells you exactly where Ohio general contractors are losing ground.
Identity (25 points) covers NAP consistency: your business name, address, and phone number matching across every directory, citation, and Google Business Profile entry. Mismatches here don't just cost points. They introduce ambiguity that causes AI models to deprioritize or exclude a business entirely when cross-referencing sources.
Legitimacy (35 points) covers review volume, star ratings, and license and insurance verification. Ohio's average rating of 4.6 stars looks strong on this dimension. The problem is review volume. The average review count across Ohio's 388 tracked contractors is 59.0, but the median is 0.0. That median tells the real story: review counts are concentrated in a small number of businesses, while the majority carry almost no social proof that AI systems can weigh.
Readability (40 points) covers website quality, JSON-LD structured data, and mobile performance. This is the heaviest category, and the one where Ohio general contractors lose the most ground. JSON-LD adoption among general contractors in Ohio: 0%.
That number deserves a direct explanation. When an AI assistant processes a query, it doesn't read your website the way a person does. It parses structured signals. JSON-LD schema markup tells a machine exactly who you are, what services you offer, where you operate, and how customers have rated you. Without it, the AI is left guessing from unstructured HTML, and it often doesn't guess in your favor. Every Ohio general contractor has a website. None of them are giving AI tools a machine-readable version of that site.
The performance gap between contractors who have closed these gaps and those who haven't is measurable. The top 10% of Ohio contractors average 65.5/100. The bottom 50% average 28.8/100. The review difference between those groups is 52 reviews versus 33 reviews: a 1.6x gap that directly feeds the Legitimacy score.
The pattern across all three categories is consistent:
| Category | Weight | Ohio Problem |
|---|---|---|
| Identity | 25 pts | NAP inconsistency across directories |
| Legitimacy | 35 pts | Median review count of 0 despite 4.6-star average |
| Readability | 40 pts | 0% JSON-LD adoption, unstructured HTML only |
Website presence is 100% across all tracked Ohio general contractors. That baseline is met. But presence without structure is the digital equivalent of a business card with no phone number: it exists, and it fails to connect.
The Readability category alone represents 40 points of potential score improvement. For most Ohio general contractors currently sitting in the 30-39 range, closing the JSON-LD gap would materially shift their position in AI-generated recommendations.

Score Distribution: Where Ohio General Contractors Actually Stand
The histogram below shows how 388 Ohio contractors distribute across score bands. The concentration tells you more than the average.
| Score Range | Contractors | Share |
|---|---|---|
| 90-100 | 0 | 0% |
| 80-89 | 2 | 1% |
| 70-79 | 5 | 1% |
| 60-69 | 23 | 6% |
| 50-59 | 23 | 6% |
| 40-49 | 64 | 16% |
| 30-39 | 184 | 47% |
| 20-29 | 84 | 22% |
| 10-19 | 3 | 1% |
| 0-9 | 0 | 0% |
Nearly half of all Ohio general contractors (47%) cluster in the 30-39 band. Another 22% sit in the 20-29 range. That means 69% of the market scores below 40, producing signals too weak for AI tools to act on with confidence.
The tier summary reinforces the same picture: 74.2% fall in the Fair tier (40-59), 12.9% reach Good (60-79), and 0% achieve Excellent (80-100). The two contractors in the 80-89 range represent 0.5% of the market. Nobody has broken 90.
The Competitive Gap Against Other Verticals
General contractors are the lagging vertical in Ohio, averaging 36.5/100. Roofers lead all Ohio verticals at 47.2/100: a 10.7-point gap that traces directly to structured data behavior. Roofers in Ohio have 20% JSON-LD adoption. General contractors have 0%.
That single difference in Readability behavior, which carries 40 points of scoring weight, accounts for most of the inter-vertical gap. Painters average 40.0/100 and landscapers 41.0/100, both ahead of general contractors despite facing similar competitive conditions.
Ohio vs. Comparable States
Ohio general contractors (36.5/100) trail peers in comparable markets. Pennsylvania averages 38.6/100 across all verticals. New York averages 40.1/100, with 14% JSON-LD adoption driving the difference. Illinois matches Ohio's overall average at 37.2/100 but general contractors in that state face the same structural problem.
The full Ohio cross-vertical picture is available in the Ohio state market report.
City-Level Variation
Within Ohio, the top-city breakdown shows meaningful local variation:
- Hilliard: 40.4/100 (leads the state)
- New Albany: 38.3/100
- Columbus: 37.2/100
- Dublin: 37.0/100
- Westerville: 34.8/100 (lags the state)
Hilliard's 40.4 average outpaces Columbus by 3.2 points and Westerville by 5.6 points. In a market where score differences of 5-10 points can determine AI recommendation placement, city of operation affects visibility in measurable ways.
What Separates the Top 10%
The contractors scoring in the top 10% average 65.5/100. The bottom 50% average 28.8/100. That 36.7-point gap does not reflect dramatically different business quality. It reflects structured data decisions and review accumulation.
Top 10% contractors average 52 reviews. Bottom 50% contractors average 33 reviews. The 1.6x review gap feeds directly into the Legitimacy category (35 points). Combined with the Readability deficit from zero JSON-LD adoption across the general contractor vertical, most Ohio contractors are leaving substantial score headroom unclaimed.
The math is direct: Readability alone offers 40 points of improvement potential. For the 184 contractors clustered in the 30-39 band, JSON-LD implementation and NAP cleanup could shift their position enough to move from AI-invisible to AI-recommended.

Action Steps: Where to Focus First
Ohio general contractors average 36.5/100. That leaves 63.5 points of room to improve. The three scoring categories tell you exactly where to start.
1. Readability (40 points): Add JSON-LD Schema First
Readability carries the heaviest weight in the AI Trust Score, and it's where Ohio general contractors lose the most ground. JSON-LD adoption among general contractors in the state: 0%. Every point available from structured data is currently unclaimed.
The comparison to Ohio roofers makes the opportunity concrete. Roofers average 47.2/100. General contractors average 36.5/100. The 10.7-point gap tracks directly to Roofers' 20% JSON-LD adoption rate versus 0% for general contractors.
What to do: Add JSON-LD schema markup to your homepage and service pages. At minimum, implement LocalBusiness schema including your business name, address, phone, service area, and hours. This is a one-time technical task. Most developers complete it in under two hours. It gives AI parsing tools the structured signal they need to recommend you with confidence.
Mobile performance and page speed also feed into Readability. Run your site through Google's PageSpeed Insights and fix any critical rendering issues flagged there.
Points at stake: Up to 40. Current general contractor baseline: near zero on structured data.
2. Legitimacy (35 points): Close the Review Gap
The review data reveals a concentration problem. Ohio's average review count across 388 tracked contractors is 59.0. The median is 0.0. Most businesses carry almost no reviews that AI systems can weigh.
Top 10% of Ohio contractors average 52 reviews. Bottom 50% average 33. That 1.6x gap feeds directly into Legitimacy scoring. Review volume, combined with license and insurance verification on record, determines most of this category's 35 points.
What to do: Request reviews from recent clients systematically, not occasionally. A follow-up message sent within 48 hours of project completion consistently produces higher response rates than requests made weeks later. Target a minimum of 25 reviews before focusing on other optimizations. Then get your license and insurance details documented in your Google Business Profile and on your website.
Points at stake: Up to 35. Current Ohio median review count: 0.0.
3. Identity (25 points): Audit Your NAP Consistency
Identity covers your business name, address, and phone number matching across every directory where you appear. Mismatches create ambiguity that AI models resolve by deprioritizing your business.
What to do: Search your business name on Google, Yelp, Angi, and HomeAdvisor. Confirm your name, address, and phone are identical across all listings. A single misformatted address or outdated phone number costs points and introduces credibility doubts that compound across AI reasoning systems.
Points at stake: Up to 25. Even minor inconsistencies reduce Identity scoring.

Frequently Asked Questions
What is an AI Trust Score and how is it calculated?
The AI Trust Score rates your business out of 100 across three weighted categories: Identity (25 points), which measures name, address, and phone consistency; Legitimacy (35 points), which covers reviews, ratings, and license verification; and Readability (40 points), which evaluates website quality, JSON-LD structured data, and mobile performance. Ohio general contractors currently average 36.5/100, meaning the typical contractor is leaving roughly 63 points of potential visibility unclaimed.
How do AI assistants decide which contractors to recommend?
AI tools like ChatGPT and Perplexity parse structured signals rather than reading your website the way a person does. They cross-reference your NAP data across directories, weigh your review volume and rating, and look for schema markup that tells them what you do and where you operate. Ohio general contractors produce almost none of those signals. The median review count across 388 tracked Ohio contractors is 0.0, and 0% have implemented JSON-LD. That combination makes most Ohio general contractors functionally invisible to AI recommendation engines.
What is JSON-LD and why does it matter for my contractor business?
JSON-LD is a structured data format embedded in your website that tells AI systems and search engines exactly who you are, what services you offer, and where you work. Without it, those systems rely on unstructured HTML and frequently skip your business in favor of competitors whose sites are machine-readable. The performance difference is measurable: Ohio roofers, who have 20% JSON-LD adoption, average 47.2/100. Ohio general contractors, at 0% adoption, average 36.5/100. That 10.7-point gap traces directly to structured data behavior.
How do Ohio general contractors compare to other states?
Ohio general contractors average 36.5/100, which is below Pennsylvania (38.6/100), New York (40.1/100), and Alberta (41.7/100). New York's advantage correlates with 14% JSON-LD adoption statewide. Ohio outperforms Florida (15.2/100), California (20.2/100), and Texas (30.3/100), but sits in the bottom tier of markets where structured data adoption is measurable. Only 0.5% of Ohio contractors across all verticals reach the Excellent tier (80-100).
