The AI Visibility Gap
Every website in our Texas dataset has a web presence. All 16,902 plumbers tracked on VerifiedNode have a URL. That part isn't the problem.
The problem is what's behind the URL.
AI assistants like ChatGPT, Gemini, and Perplexity don't browse websites the way humans do. They read structured data: machine-readable signals that identify a business, confirm its legitimacy, and describe its services. Without those signals, your website is effectively invisible to AI recommendations, regardless of how well it ranks on Google.
Only 16% of Texas plumbers have implemented JSON-LD structured data. That's roughly 2,704 contractors out of 16,902. The remaining 84%, approximately 14,198 businesses, are operating without the technical foundation that AI systems rely on to surface contractors in response queries.
The score data reflects this directly. The average AI Trust Score across all Texas plumbers is 35.7 out of 100. The median is 37.0. Both figures sit well below the threshold where AI systems treat a contractor as a credible, recommendable source.
The score breaks down across three categories:
- Identity (25 points): Business name, address, and phone consistency across the web
- Legitimacy (35 points): Reviews, ratings, and license or insurance verification
- Readability (40 points): Website quality, JSON-LD structured data, and mobile-friendliness
Readability carries the most weight, and it's where most Texas plumbers lose ground. JSON-LD adoption is the single fastest technical fix available, yet 84% of the state's plumbers haven't implemented it.
The tier distribution shows how concentrated the problem is:
| Score Tier | Range | Share of Texas Plumbers |
|---|---|---|
| Excellent | 80-100 | 1.7% (~287 contractors) |
| Good | 60-79 | 17.7% |
| Fair | 40-59 | 56.8% |
| Below Fair | Below 40 | 23.8% (~4,023 contractors) |
Only 287 contractors have reached Excellent status. Nearly 4,023 score below 40, a threshold where AI visibility is effectively zero.
The gap between top and bottom performers is significant. The top 10% average 69.7 out of 100, with an average of 239 reviews. The bottom 50% average 22.0, with 136 reviews on average. Top performers carry 1.8 times more reviews, and their structured data signals amplify that social proof into AI-readable legitimacy.
Plumbers do outperform the broader state average. The plumber vertical averages 42.3, compared to 35.7 across all contractor categories tracked in Texas. But outperforming a low baseline isn't the same as being AI-visible.

The contractors winning AI recommendations aren't doing anything exotic. They have clean structured data, verified identities, and consistent review profiles. The gap is technical, and it's closeable.
What AI Models Actually Check
The 35.7 average score isn't random. It maps directly to three scoring categories, each weighted by how much AI systems depend on that signal type.
Identity: 25 points
This category covers name, address, and phone consistency across your website, Google Business Profile, and third-party directories. AI models cross-reference these signals to confirm a business is real and operating at a known location. Inconsistencies, a slightly different business name on Yelp versus your website, an old address still indexed somewhere, drop your Identity score immediately.
For most Texas plumbers, Identity is the easiest category to clean up. The signals are factual, not technical.
Legitimacy: 35 points
Legitimacy is the heaviest single category. It covers reviews, star ratings, and license or insurance verification. Texas plumbers average 4.51 stars, which is a strong signal on its own. The review volume picture is more complicated.
The statewide average is 118 reviews per contractor. The median, however, is 0.0. That means half of the 16,902 tracked plumbers have zero reviews indexed where AI systems can read them. A 4.51-star average across the segment means nothing for a contractor with no verifiable review history.
The top 10% of Texas plumbers average 239 reviews. The bottom 50% average 136. That 1.8x gap in review count directly translates to Legitimacy score differences, because volume and recency both factor into how AI systems assess credibility.
Readability: 40 points
Readability carries the most weight in the scoring model, and it's where the largest share of Texas plumbers lose ground. This category covers website quality, mobile-friendliness, and JSON-LD structured data.
JSON-LD is the specific signal where the gap is most visible. Only 16% of Texas plumbers have implemented it statewide. Within the plumber vertical specifically, adoption reaches 23%, the highest of any vertical tracked in Texas and well above the 16% statewide average across all contractor categories. But 23% still means 77% of Texas plumbers are missing the technical layer AI models use to parse service descriptions, service areas, and business attributes from a webpage.
Every contractor in this dataset has a website. That 100% website presence contributes to base Readability scores, but a website without structured data is incomplete from an AI perspective. The site exists; its content isn't machine-readable in the format AI systems prioritize.
The three categories compound each other. A contractor with clean Identity signals, a verified license, 200 reviews, and properly implemented JSON-LD can realistically reach the Good or Excellent tier. A contractor with a working website, decent reviews, and no structured data is likely scoring in the Fair range at best, and Fair means AI recommendations go elsewhere.

Scoring Deep-Dive
Texas plumbers average 42.3 on AI Trust Score, the highest of any vertical tracked in the state. That number sounds encouraging until you map it against what the distribution actually shows.
| Score Range | Contractors | Share |
|---|---|---|
| 0-9 | 2,166 | 13% |
| 10-19 | 403 | 2% |
| 20-29 | 2,453 | 15% |
| 30-39 | 5,004 | 30% |
| 40-49 | 3,388 | 20% |
| 50-59 | 1,497 | 9% |
| 60-69 | 1,410 | 8% |
| 70-79 | 328 | 2% |
| 80-89 | 229 | 1% |
| 90-100 | 24 | 0% |
Sixty percent of Texas plumbers score below 40. Only 1.7% reach the Excellent tier (80-100). The Good tier (60-79) captures 17.7%. The plurality of the market, 56.8%, sits in Fair (40-59): visible enough to appear in a directory, not credible enough for AI recommendation.
The category dragging most contractors down is Readability (40 points). It covers website quality, mobile-friendliness, and JSON-LD structured data. JSON-LD adoption among Texas plumbers sits at 23%, the highest of any vertical tracked in Texas but still meaning 77% of plumbers lack structured data entirely. Across all Texas contractor categories, JSON-LD adoption is just 16%. HVAC-R sits at 0%.
Readability is where scores collapse. A functional website contributes to the base score, but a site without JSON-LD is incomplete from an AI perspective. Identity (25 points) and Legitimacy (35 points) can both be strong, and a contractor can still land in Fair if Readability is missing the structured data layer.
How Texas Compares
Texas trails several Canadian provinces on average AI Trust Score. Ontario averages 38.5, Alberta 38.5, and Quebec 37.9, all above Texas's 35.7 statewide average across all contractor categories. Manitoba leads the tracked regions at 41.7.
Texas does outperform several large U.S. states: California averages 21.5, Florida 19.8, and Illinois 17.2. But those states face different baseline conditions. Matching California isn't the target; Excellent tier is.
City-Level Spread
Texas plumbers operate across 93 cities in the VerifiedNode dataset. The cities with the strongest average scores share a pattern: suburban markets north and northwest of Austin where newer businesses tend to have cleaner digital setups.
Top cities by average AI Trust Score:
- Haslet: 47.2
- Round Rock: 47.0
- Cedar Park: 46.4
- Leander: 46.0
- Bastrop: 45.7
Bottom cities tell a different story. Texas City, Smithville, Santa Fe, San Leon, and Red Rock all average 0.0. These aren't markets with no plumbers. They're markets where the contractors present have no structured data, no verified identity signals, and no indexed reviews readable by AI systems.
A 47-point gap between the top and bottom cities in a single state reflects how unevenly basic digital infrastructure is distributed, not how unevenly plumbing work is distributed.
The city-level gap also matters competitively. If you're operating in Round Rock alongside 42 tracked plumbers and your score is in the Fair tier, you're losing AI recommendations to contractors in the Good and Excellent range, regardless of how long you've been in business.

Action Steps: Fixes Ranked by Point Impact
The path from Fair to Good (60-79) is achievable for most Texas plumbers. The top 10% average 69.7, and that benchmark isn't built on anything inaccessible. It's built on three categories, each with specific, measurable fixes.
1. Readability: 40 Points Available
Readability is the highest-weight category and the one with the most recoverable ground. Three signals drive this score: website quality, mobile-friendliness, and JSON-LD structured data.
JSON-LD is the priority. Only 23% of Texas plumbers have implemented it. The other 77% are missing the technical layer AI systems use to read your service types, service area, and business attributes. Adding JSON-LD to your site is a one-time technical implementation. It doesn't require a website rebuild. It requires adding a structured data block that identifies your business name, address, phone, services, and geographic coverage in a format AI models can parse directly.
Mobile-friendliness and page speed are the other Readability factors. If your site loads slowly or renders poorly on a phone, both your Readability score and your broader AI credibility take a hit.
Readability checklist:
- Add JSON-LD structured data (highest single impact)
- Confirm mobile rendering on at least two device types
- Run a page speed check and address any failures over 3 seconds
2. Legitimacy: 35 Points Available
Legitimacy covers reviews, ratings, and license or insurance verification. Texas plumbers average 4.51 stars, which is a solid foundation. The volume problem is more significant.
The median review count across 16,902 tracked Texas plumbers is 0.0. Half the contractors in this dataset have no indexed reviews that AI systems can read. The top 10% average 239 reviews. If your review count is below that threshold, closing the gap is the fastest Legitimacy move available.
Review recency matters alongside volume. AI systems weight recent reviews more heavily. A contractor with 50 reviews from the last 12 months outperforms a contractor with 200 reviews, the most recent from 2022.
License and insurance verification feeds directly into Legitimacy scoring. If your credentials aren't verified on your VerifiedNode profile, you're leaving points on the table in the heaviest scoring category.
Legitimacy checklist:
- Target 239+ reviews to match top-10% volume
- Prioritize review recency alongside count
- Verify your license and insurance status on your profile
3. Identity: 25 Points Available
Identity is the most fixable category. It covers your business name, address, and phone number (NAP) consistency across your website, Google Business Profile, Yelp, and any other directories where you're listed.
A single inconsistency, an old suite number, a slightly different business name variant, an outdated phone number, reduces your Identity score. AI systems cross-reference these signals to confirm you're a real, operating business at a known location.
Identity checklist:
- Audit your NAP across Google Business Profile, Yelp, and your website
- Remove or correct any outdated listings
- Ensure your business name is identical across every platform
The Achievable Target
Only 1.7% of Texas plumbers currently score Excellent (80-100). The Good tier (60-79) captures 17.7%. Moving from Fair into Good requires meaningful progress across all three categories, not a perfect score in one.
A contractor who adds JSON-LD, verifies their license, and cleans up NAP inconsistencies can realistically move 15 to 20 points from a Fair baseline. That's the distance between invisible to AI systems and recommendable.

Frequently Asked Questions
What is an AI Trust Score?
An AI Trust Score measures how visible and credible your business appears to AI systems like ChatGPT, Gemini, and Perplexity. The score runs from 0 to 100 and breaks into three categories: Identity (25 points, covering name, address, and phone consistency), Legitimacy (35 points, covering reviews, ratings, and license verification), and Readability (40 points, covering website quality, JSON-LD structured data, and mobile-friendliness). The average AI Trust Score across all Texas contractors is 35.7 out of 100. For plumbers specifically, the average is 42.3. Check your current score at VerifiedNode's score finder.
How do contractors get found by AI assistants?
AI models don't browse websites the way humans do. They parse structured signals: consistent business identity, verified credentials, review volume, and machine-readable structured data. Contractors with stronger signals across all three scoring categories appear in AI-generated recommendations. Right now, only 1.7% of Texas plumbers score in the Excellent tier (80-100). The top 10% average 69.7 out of 100 and carry an average of 239 reviews. Those two factors, technical readability and review volume, are what separate contractors who get recommended from those who don't.
What is JSON-LD, and why does it matter for plumbers?
JSON-LD is a structured data format added to your website's code. It tells AI systems your business name, address, phone number, services, and service area in a format they can read directly, without interpreting your page layout. Only 23% of Texas plumbers have implemented JSON-LD. The other 77% have websites that AI systems can visit but can't fully parse. JSON-LD is the single highest-impact fix in the Readability category, which carries 40 points, the largest weight in the scoring model.
How can Texas plumbers improve their AI visibility score?
The three highest-impact moves map directly to the scoring categories. First, implement JSON-LD structured data on your website (Readability, 40 points). Second, build review volume and recency toward the top-10% benchmark of 239 reviews (Legitimacy, 35 points). Third, audit your business name, address, and phone for consistency across every directory where you appear (Identity, 25 points). Currently, 56.8% of Texas plumbers score in the Fair range (40-59). Addressing all three categories can realistically move a Fair-tier contractor into the Good range (60-79).
