The AI Visibility Gap
Of 1,827 Florida plumbers tracked in the VerifiedNode database, 1,021 score between 0 and 9 out of 100. That is 56% of the state's plumbing contractors effectively invisible to AI-driven recommendation systems.
The median AI Trust Score for Florida plumbers is 0.0/100. Half the state scores nothing. The average pulls to 19.8/100 only because a small group of well-optimized contractors lifts the mean. The top 10% average 67.9/100. The bottom 50% average 0.0/100. That gap is not marginal. It is structural.
Why Websites Alone Are Not Enough
Every Florida plumber in this dataset has a website. Website presence sits at 100%. But AI assistants do not read websites the way humans do. They parse structured signals: JSON-LD schema markup, consistent business identity across platforms, verified reviews, and mobile-optimized content.
Only 13% of Florida plumbers have JSON-LD structured data in place. That means roughly 1 in 8 contractors is actually legible to AI systems in the way that drives recommendations. The other 87% have websites that look functional to human visitors but register as near-empty to AI models scanning for trust signals.
Florida's 13% JSON-LD adoption rate is above the national average of 8.6% across 65 tracked regions. That is the only flattering comparison available. Against Texas, Florida falls significantly short: Texas plumbers average 35.7/100 versus Florida's 19.8/100, with Texas JSON-LD adoption at 16%.
How AI Trust Scores Are Calculated
The AI Trust Score runs on three weighted categories:
- Identity (25 points): Business name, address, and phone number consistency across directories and platforms
- Legitimacy (35 points): Review volume, star ratings, and license and insurance verification
- Readability (40 points): Website technical quality, JSON-LD structured data implementation, and mobile-friendliness
Readability carries the heaviest weight, which explains why 56% of contractors score in the 0-to-9 range despite having functional websites. A site without structured data fails the Readability component almost entirely.
Who Is Winning and By How Much
Only 1.2% of Florida plumbers score in the Excellent tier (80-100). Another 13.9% reach the Good tier (60-79). The remaining 84.9% sit in Fair, Below Average, or effectively unscored territory.
The review gap reinforces this divide. Top 10% performers average 54 reviews. Bottom 50% performers average 26. Top performers carry 2.1 times more reviews, which directly affects the Legitimacy score component.

The gap between AI-visible and AI-invisible contractors in Florida is not closing on its own. The contractors already optimized are pulling further ahead every month.
What AI Models Check
The three scoring categories are not arbitrary. Each one maps to a specific type of signal that AI recommendation engines use to evaluate whether a contractor is trustworthy enough to surface in a response.
Identity: 25 Points
Identity covers NAP consistency: your business name, address, and phone number matching exactly across Google Business Profile, your website, and third-party directories. A mismatch between your Google listing and your website footer is enough to suppress your score in this category.
For AI models, inconsistent identity signals ambiguity. An assistant recommending a plumber to a homeowner cannot confidently surface a business whose contact information conflicts across sources. The model reads that conflict as a trust failure.
Legitimacy: 35 Points
Legitimacy pulls from review volume, star ratings, and verified license and insurance status. Florida plumbers in this dataset average 4.76 stars and 40.0 reviews. Both numbers look healthy until you check the median: 0.0 reviews.
The median review count of 0.0 means more than half the tracked plumbers in Florida carry no verifiable review signal whatsoever. A 4.76-star average reflects only the contractors who have any reviews at all. For AI models, zero reviews means zero evidence of real-world performance.
The top 10% of Florida plumbers average 54.0 reviews. The bottom 50% average 26.0. That 2.1x gap translates directly into Legitimacy score separation. Review volume is not just a vanity metric here: it is the primary input for 35 of 100 possible points.
Readability: 40 Points
Readability is the heaviest category and the one where Florida plumbers fail most completely. It covers website technical quality, JSON-LD structured data, and mobile-friendliness.
Every plumber in this dataset has a website. Readability failures in Florida are not about existence. They are about structure. JSON-LD adoption sits at 13% statewide. Without JSON-LD schema markup, your site cannot communicate its content in a format that AI systems parse reliably. The site exists, but its signals do not.
This is why 56% of Florida plumbers score between 0 and 9. A functional website with no structured data, no consistent identity signals, and no review footprint fails all three categories simultaneously. The median score of 0.0 is not an outlier condition: it is the default outcome for a contractor who has not addressed any of these layers.
What Combined Strength Looks Like
Coral Gables leads all Florida cities with an average AI Trust Score of 48.2/100. That is still below the Good tier threshold of 60, but it illustrates what happens when Identity, Legitimacy, and Readability inputs compound together rather than cancel each other out.
Across the full state: 1.2% of plumbers score Excellent (80-100), 13.9% score Good (60-79), 24.5% score Fair (40-59), and 60.4% fall below 40.

Score Distribution: Where Florida Plumbers Actually Stand
The histogram tells the full story. More than half of Florida's 1,827 plumbers are clustered at the bottom of the range, with a sharp drop-off before any meaningful score tier.
| Score Range | Contractors | Share of State |
|---|---|---|
| 0–9 | 1,021 | 56% |
| 10–19 | 3 | 0% |
| 20–29 | 150 | 8% |
| 30–39 | 190 | 10% |
| 40–49 | 169 | 9% |
| 50–59 | 112 | 6% |
| 60–69 | 144 | 8% |
| 70–79 | 18 | 1% |
| 80–89 | 19 | 1% |
| 90–100 | 1 | 0% |
One contractor in the entire state scores 90 or above. Nineteen score between 80 and 89. The 60-to-79 band, which represents genuinely competitive AI visibility, holds 162 contractors combined: 8.9% of the market.
The 10-to-19 range is almost empty: three contractors. That is not a rounding artifact. It reflects how the scoring components interact. A contractor who fixes Identity but leaves Readability unaddressed scores either very low or moderately well, with little in between.
Florida vs. Other States
Florida's 19.8 average score ranks poorly against comparable markets:
| Region | Avg Score | JSON-LD Adoption |
|---|---|---|
| Ontario | 38.5/100 | 5% |
| Texas | 35.7/100 | 16% |
| New York | 36.4/100 | 14% |
| California | 21.5/100 | 11% |
| Florida | 19.8/100 | 13% |
Florida's JSON-LD adoption of 13% exceeds the national average of 8.6% across 65 tracked regions. That is a genuine advantage over markets like Ontario (5%) and California (11%). The problem is that adoption rate alone does not move scores when the contractors implementing JSON-LD are also the ones already optimizing Identity and Legitimacy. The bottom 56% have none of these elements in place.
The Readability Problem
Readability carries 40 of 100 possible points. It is the single largest scoring category, and JSON-LD structured data is its primary determinant. At 13% adoption statewide, 87% of Florida plumbers forfeit most or all of that 40-point block before any other factor is considered.
Across verticals, the adoption gap is visible. Painters and landscapers lead at 33% JSON-LD adoption each. Roofers and HVAC contractors sit at 17%. Plumbers reach 13%. General contractors trail at 7%. The corresponding average scores follow the same sequence: landscapers 29.3, roofers 27.2, painters 22.3, plumbers 19.8, general contractors 12.7, HVAC 11.3.
JSON-LD adoption does not fully explain score differences across verticals, but the correlation is consistent enough that Readability failure is the shared floor dragging every trade down.
City-Level Variation
Geography matters. Coral Gables plumbers average 48.2/100, the highest of any Florida city in this dataset. Coconut Grove follows at 36.8. Tampa sits at 21.3, Miami at 19.5, and Jacksonville at 19.0.
The Coral Gables-to-Jacksonville spread of 29.2 points within a single state reflects local market concentration: cities with more optimized contractors raise the local average, which in turn signals denser competition for AI-driven referrals in those markets.

Action Steps: What to Fix and in What Order
60.4% of Florida plumbers score below 40. The three-category structure of the AI Trust Score means there is a defined sequence of fixes, each with a calculable point ceiling. Work top-down by weight.
1. Readability: Up to 40 Points
Readability is the largest category and the one where most Florida plumbers lose the most ground. JSON-LD structured data is the primary lever.
At 13% statewide adoption, 87% of Florida plumbers have no structured data markup on their sites. Adding JSON-LD schema (business type, service area, contact details, operating hours) makes your site parseable to AI systems in a way that plain HTML does not. This single fix recovers the largest block of Readability points available.
Beyond JSON-LD, mobile-friendliness and page speed contribute to the Readability score. Both are addressable without a full site rebuild. Run a Google PageSpeed Insights check. Fix render-blocking scripts and oversized images. These are not edge cases: they are baseline requirements for the 40-point Readability block.
Coral Gables plumbers average 48.2/100 without being exceptional on any single dimension. That score reflects contractors who have addressed Readability at a basic level. It is a realistic short-term target for any contractor currently below 20.
2. Legitimacy: Up to 35 Points
The median review count across Florida's 1,827 tracked plumbers is 0.0. The state average of 40.0 reviews is carried entirely by contractors who have any reviews at all. More than half of Florida plumbers have zero verifiable review signal, which means zero Legitimacy input from that component.
The top 10% of Florida plumbers average 54.0 reviews. The bottom 50% average 26.0. That 2.1x difference translates directly into score separation in the Legitimacy category.
Practical fixes here are straightforward: a post-job review request process (text or email), a direct Google review link in your follow-up communications, and license and insurance verification through your VerifiedNode profile. License status is a binary input: verified or not. Unverified contractors leave Legitimacy points unclaimed regardless of their review volume.
The state average of 4.76 stars shows that Florida plumbers who do collect reviews tend to collect good ones. The problem is volume, not quality.
3. Identity: Up to 25 Points
NAP consistency is the quietest score killer in the dataset. Your business name, address, and phone number need to match exactly across your Google Business Profile, your website, and every directory listing where your business appears. Abbreviations, suite number formatting differences, and outdated phone numbers all register as conflicts.
Audit every directory listing where your business appears. Priority targets: Google Business Profile, Yelp, Angi, the BBB, and any local chamber listings. A single conflicting entry suppresses your Identity score.
The Gap Is Closable
The top 10% of Florida plumbers average 67.9/100. The state average is 19.8. That 48.1-point gap is not the result of superior businesses: it is the result of structured optimization across all three scoring categories. The contractors scoring in the 60-to-79 range have addressed JSON-LD, review volume, and NAP consistency. Most of the state has addressed none of them.

Frequently Asked Questions
What is the average AI Trust Score for Florida plumbers?
Florida's 1,827 tracked plumbers average 19.8/100. That number is misleading as a benchmark because the median score is 0.0/100. The average is pulled upward by a small group of optimized contractors. In practice, 1,021 plumbers (56% of the state) score between 0 and 9. Texas plumbers, by comparison, average 35.7/100. Florida's gap relative to that market is 15.9 points, driven primarily by Readability failures at scale.
What is JSON-LD and why does it matter for plumbers?
JSON-LD is structured data markup that tells AI systems and search engines what your business is, where it operates, what services it offers, and how to contact you. Without it, AI models have to infer that information from unstructured HTML, which they do unreliably. Only 13% of Florida plumbers have JSON-LD implemented. The remaining 87% are forfeiting most of the Readability category, which carries 40 of 100 possible points in the AI Trust Score. That is the single largest scoring block available, and the majority of the state is scoring near zero on it.
Why do I score low even though I have a website?
Website presence in Florida is 100%: every tracked plumber has a site. That metric alone means nothing to AI systems. The Readability category (40 points) measures structured data implementation, mobile-friendliness, and technical quality, not mere existence. The Legitimacy category (35 points) requires verified reviews, ratings, and license confirmation. The Identity category (25 points) requires exact NAP consistency across all platforms. A website with no JSON-LD, no reviews, and inconsistent directory listings scores at or near zero across all three categories simultaneously. That is why the 0-to-9 band holds 56% of the state.
How many Florida plumbers actually rank as Excellent?
One contractor in the entire state scores 90 or above. Nineteen score between 80 and 89. Combined, only 1.2% of Florida plumbers reach the Excellent tier (80-100). The top 10% of the state average 67.9/100, which falls in the Good tier. Reaching that level requires review volume (top performers average 54.0 reviews versus 26.0 for the bottom half), JSON-LD implementation, and consistent identity signals across directories.
How do I check my own AI Trust Score?
