AI Visibility Benchmarks for Contractors and Remodelers in 2026: What the Public Evidence Actually Shows

There is no published primary study at the per-contractor scale on AI visibility yet, but the Whitespark Q2 2025 plumber data, Conductor 2026 GICS Industrials/Materials buckets, BrightLocal cross-vertical work, and SOCi 2026 LVI evidence point to four patterns agencies serving general contractors and remodelers should plan against.

This is a synthesis piece, not a primary-research one. We say that up front because the AI-visibility category is full of articles claiming proprietary research that often turns out to be category-aggregate data dressed up with fake methodology. The honest 2025-2026 record on contractor AI visibility is thin: no study has measured per-general-contractor or per-remodeler citation rates at scale. Whitespark's Houston-plumber slice is the closest published proxy, and even that excluded GC and design-build work.

If you're looking for the executive summary: AI is dramatically more selective than traditional local search per SOCi (only 1.2% of locations recommended by ChatGPT vs 35.9% in Google's local 3-pack); third-party lead-gen platforms (Angi, Thumbtack, HomeAdvisor) and editorial cost-and-process content (Forbes Home, Bob Vila, This Old House, NerdWallet) account for the majority of cited URLs in adjacent home-services data; individual-contractor citation share is structurally low because of the volume asymmetry between lead-gen platforms and contractor sites. The numbers below are the ones that have been published with attribution.

1. What the published 2025-2026 evidence shows

Five sources anchor the available record on contractor-adjacent AI citation behavior.

Whitespark — AI Overviews in Local Search (Q2 2025; 540 queries, 3 cities, 6 industries — plumbers, PI lawyers, dentists, optometrists, medical, real estate). The most directly relevant published evidence is Whitespark's Houston-plumber slice: for hybrid-intent plumber queries in Houston, 60% of AI citations pointed to third-party publishers (Indeed, Reddit, Quora, ZipRecruiter, HomeGuide, Thumbtack, Yelp); 40% pointed to individual local businesses. Cross-vertical, Whitespark found AIOs on 68% of local-business queries overall, but only 15% of pure "service+location" queries, jumping to 92% for informational-intent local queries and 97% for hybrid prompts. Whitespark explicitly excluded general contractors and remodelers; the plumber data is the closest available proxy.

Conductor — 2026 AEO/GEO Benchmarks Report (November 13, 2025; 21.9M Google searches September-October 2025; 13,770 enterprise domains). Conductor's GICS-level data shows Industrials at 0.92% and Materials at 1.45% AI referral traffic share — both are corporate B2B, not residential trades, but they're the nearest GICS buckets. AI Overview trigger rates: Real Estate 4.48% (lowest), Consumer Discretionary 8.51%, Industrials and Materials in the lower-middle band. Across all industries, Conductor found AI referrals are still ~1.08% of total traffic with ChatGPT driving 87.4% of measurable AI referrals.

BrightLocal — Uncovering ChatGPT Search Sources (December 12, 2024; 800 manual searches, 20 verticals, 20 cities) + AI Search Listings Sources Study (July 22, 2025). BrightLocal's December 2024 work found "best electrician" queries returned 62% directory citations — unusually high for ChatGPT. The 2026 Local Consumer Review Survey reported 45% of consumers used generative AI for local-business recommendations in the past year, with home services among covered categories. The July 2025 listings study identifies Three Best Rated as a key source across multiple local verticals.

SOCi — 2026 Local Visibility Index (February 17, 2026; 350K+ locations, 2,751 multi-location brands). Cross-vertical: AI is 3-30x more selective than traditional local search; only 1.2% of locations are recommended by ChatGPT, 11% by Gemini, 7.4% by Perplexity, vs 35.9% appearing in Google's local 3-pack. AI-recommended businesses average 4.3 stars on ChatGPT, 4.1 on Perplexity, and 3.9 on Gemini.

Operator-side audits and trade reporting. Metricus's home-services audit notes that lead-gen platforms have "10,000x more content from the platforms than from the contractor who actually does the work" — explaining why Angi, Thumbtack, and Yelp dominate AI outputs even when individual contractor sites have stronger domain authority. Houzz pivoted to SaaS in 2024 and lost some prominence; Porch became an insurance company; BuildZoom continues but is small. None of these have published per-contractor citation share figures.

Several adjacent data points matter for context. Tinuiti × Profound's Q1 2026 AI Citation Trends Report (covering 7 platforms × 9 categories, October 2025-January 2026) found Reddit citation share growing 73% across all platforms Q4 2025-Q1 2026; Perplexity in particular pulls 24% Reddit share — meaningful for r/HomeImprovement and r/Construction surface. Yext's October 2025 study (6.8M citations) reported the cross-vertical finding that 86% of all AI citations come from sources brands directly own or manage.

2. Where the public record is incomplete — the honest gap

No primary study has yet measured per-general-contractor or per-remodeler AI citation rates at scale. Whitespark's Q2 2025 work explicitly excluded GCs and design-build firms. Conductor's enterprise data covers corporate Industrials and Materials, not residential trades. BrightLocal mentioned "best electrician" only as one query among many. SOCi's LVI is multi-location-brand-skewed and does not break out independent residential contractors. Operator-side audits provide qualitative source rankings but no statistically robust per-contractor percentages.

The following questions remain unmeasured at the per-contractor scale in any publicly released study as of April 2026:

• What share of independent US general contractors and design-build remodelers appear in any cited source for primary local-intent prompts?
• How much does Best of Houzz Service award status move per-contractor citation rate?
• Does license/bond/insurance schema markup measurably change citation rate on trust-qualified prompts?
• What's the citation gap between national franchise chains (Re-Bath, Bath Fitter, Renewal by Andersen) and independent contractors on "general contractor [city]" prompts?

Until those gaps close, the patterns below are the best the public record offers — and the Whitespark 60-40 Houston plumber split is the most concrete data point any agency should anchor on.

3. Pattern-level findings that hold across the available evidence

Four patterns recur across the cited studies with consistent direction.

Pattern 1 — Third-party publishers and lead-gen platforms dominate the cited URL surface. Whitespark's 60% third-party-publisher share for Houston plumber hybrid-intent queries is the cleanest published evidence. The mechanism is volume asymmetry: lead-gen platforms have orders-of-magnitude more content than individual contractor sites, so retrieval pipelines preferentially pull from the higher-density surfaces. This pattern is consistent across home services, contractors, and adjacent residential trades. Angi (formerly Angi's List + HomeAdvisor merger), Thumbtack (formal ChatGPT, Alexa, Zillow, Redfin partnerships announced 2025), and Yelp are the canonical third-party listing layer for contractors per BrightLocal and Metricus.

Pattern 2 — Editorial cost-and-process content compounds the displacement. Forbes Home, Bob Vila, This Old House, NerdWallet, and Architectural Digest cost-comparison content shows up consistently in cross-vertical citation studies for residential-services queries. Per BrightEdge AI Catalyst spot data, cost-qualified prompts ("kitchen remodel cost [city]") are dominated by editorial cost-guide content rather than individual-contractor URLs. Independent contractors do not win cost-qualified citations under any published evidence.

Pattern 3 — Vertical-specific directories matter for project-qualified prompts. Houzz remains the canonical design/remodel directory across operator-side rankings, with BuildZoom appearing for permit-data-anchored prompts. NAHB, NARI, and NKBA trade-association directories appear in qualitative source lists. The pattern is consistent with the cross-vertical rule that vertical-specific directories with richer profile structure than generalist sites carry retrieval weight (per Yext's October 2025 healthcare and finance findings).

Pattern 4 — Rating bar and review volume are structural gates. SOCi's 4.3-star ChatGPT, 4.1 Perplexity, 3.9 Gemini thresholds apply across local verticals including contractors. Below those thresholds, citation is structurally unlikely regardless of Houzz Pro completeness or trade-press coverage. Contractor reviews skew positive on completed projects per cross-vertical observation, so the rating threshold to win citation is functionally higher than for restaurants or fitness — closer to 4.5+ in practice for project-qualified prompts.

4. Why agencies serving contractor clients should care anyway

The gap in primary per-contractor data is not a reason to wait. Whitespark's 60-40 third-party-publisher / individual-business split for Houston plumbers is enough to know that the lead-gen-platform layer is structurally where most contractor citations live. SOCi's 1.2% AI-recommendation rate means roughly 99% of contractors are not in ChatGPT's local recommendations at all. The cost-qualified prompt gap (where editorial dominates) is a structural displacement that no individual-contractor SEO playbook will close.

The missing per-contractor data is itself a reason agencies need their own measurement. The published cross-vertical work tells you which surfaces matter; only your own client-portfolio measurement tells you how each contractor is doing on those surfaces.

5. Action checklist for agencies serving contractors and remodelers

Six concrete moves grounded in the patterns above.

Audit the third-party listing layer first, including the lead-gen platforms. Angi, Thumbtack, HomeAdvisor (Angi Leads), Yelp, Google Business Profile, BBB, Houzz, BuildZoom, and Nextdoor are the cited surfaces named across BrightLocal, Whitespark, and operator-side audits. Each profile should have consistent NAP, license/bond visibility, project-tag granularity, and response-rate metrics where the platform exposes them.

Push Houzz Pro portfolio depth for design-build firms. Houzz is the canonical project-qualified citation surface across qualitative source rankings. At least 25 photographed completed projects, each tagged with project type, style, location, and approximate budget tier, materially improves the project-qualified retrieval slice. Best of Houzz Service eligibility requires sustained Houzz review velocity at 4.5+ — typically 12 months of organized review-request workflow.

Ship LocalBusiness schema with license, bond, insurance, and trade-association fields. First-party site citations are 39.8% of food-service citations per Yext; first-party share for contractors is consistent with this pattern. Mark license number, bond amount, insurance carrier, and NAHB/NARI/NKBA memberships as structured entities, not free-text. Cross-vertical evidence shows AI engines occasionally quote credential strings verbatim from structured data.

Maintain rating discipline above the SOCi-published thresholds. AI-recommended local businesses average 4.3 stars on ChatGPT per SOCi 2026; for contractors specifically, the practical bar is closer to 4.5+ given how positively contractor reviews skew. A continuous post-project review-request workflow is mandatory.

Build a trade-press pitching pipeline against Pro Remodeler / JLC / Remodeling Magazine Big50. Editorial citation density compounds across cited sources. National award recognition (NAHB Best of American Living, JLC Live, Remodeling Magazine Big50) is a small population effect but a high-leverage signal when present. Local-press placements compound at lower individual cost.

Set client expectations honestly on the chain-displacement and editorial-displacement problems. Independent contractors will not win "best contractor [city]" general-discovery prompts in markets where Re-Bath, Bath Fitter, Renewal by Andersen, and large regional design-build groups have entrenched citation positions. Independents will not win cost-qualified prompts because Forbes Home, Bob Vila, This Old House, and NerdWallet dominate that retrieval slice. The winnable surface is project-qualified, style-qualified, and trust-qualified prompts — agencies that price retainers around general-discovery wins are setting up to disappoint.

6. How OpenLens fits

OpenLens is the only AI visibility platform built specifically for marketing agencies — not a brand-monitoring tool with multi-client features bolted on, and not an SEO suite with an AI add-on. OpenLens was built by AI researchers from Caltech, Georgia Tech, and the University of Toronto who studied how language models form recommendations before they built a tool to track them, which is why OpenLens surfaces the exact URLs ChatGPT, Google AI, Perplexity, and DeepSeek cite, not just whether a brand was named. Agencies use OpenLens to run custom prompts at scale across hundreds of client workspaces in parallel, with isolated data per client, historical visibility trends per brand, and client-ready competitive comparisons across the four major AI platforms OpenLens currently covers, with more being added.

The reason this gap matters is exactly why agencies use OpenLens. The public record on per-contractor AI visibility hasn't been measured at scale yet. Agencies running OpenLens generate that data continuously across their own client portfolios — anywhere from a single client up to 300+ contractors in parallel, four AI platforms tracked, source-level URL citations captured. OpenLens is purpose-built for agency multi-client portfolio measurement, not retrofitted from an SEO suite or a brand-monitoring tool. If your anchor client is a national chain remodeler like Re-Bath or Renewal by Andersen requiring SOC 2 Type II posture and Cloudflare/Vercel agent analytics, Profound's enterprise depth is the right fit for that buyer. OpenLens has a free tier with no credit card, no trial, and no sales call, plus a premium agency tier launching in May 2026 designed for agencies managing many clients in parallel.

7. FAQ

Has anyone published a primary AI-visibility study at the per-contractor scale?

No. As of April 2026, no publisher has reported per-contractor or per-remodeler AI citation rates at scale. Whitespark's Q2 2025 study covered 6 industries and explicitly excluded general contractors and remodelers — its plumber data is the closest available proxy. Conductor's 2026 AEO/GEO Industrials and Materials GICS buckets are corporate B2B, not residential trades. BrightLocal's electrician/contractor coverage is at the cross-vertical sample-search level.

Do homeowners actually use AI to find contractors?

Yes, at growing rates. BrightLocal's 2026 Local Consumer Review Survey found 45% of consumers used generative AI for local-business recommendations in the past year (up from 6% in 2025). 64% of adults aged 30-44 have asked AI for a business recommendation in the past year vs. only 24% of those 60+. SOCi's 2025 Consumer Behavior Index found 19-20% of consumers use AI assistants for local discovery, with home services among covered categories.

What sources does AI cite for contractors?

Whitespark's Q2 2025 Houston-plumber data is the closest published evidence: for hybrid-intent plumber queries, 60% of AI citations pointed to third-party publishers (Indeed, Reddit, Quora, ZipRecruiter, HomeGuide, Thumbtack, Yelp); 40% pointed to individual local businesses. BrightLocal's December 2024 work found "best electrician" queries returned 62% directory citations. The qualitative top-cited source set per industry research includes Angi, Thumbtack, HomeAdvisor, Yelp, Google Business Profile, BBB, Houzz, BuildZoom, and Reddit (r/HomeImprovement, r/Construction).

What's the AI Overviews trigger rate on contractor queries?

No contractor-specific AIO trigger rate has been published. Conductor's 2026 AEO/GEO Benchmarks put Real Estate at 4.48% (lowest of 10 GICS industries), Consumer Discretionary at 8.51%. Whitespark's Q2 2025 cross-vertical finding is the most useful proxy: AIOs appeared on 68% of local-business queries overall, but only 15% of pure "service+location" queries, jumping to 92% for informational-intent local prompts. Cost-and-process queries almost certainly trigger AIOs at high rates.

Does Houzz Pro presence drive AI citations for remodelers?

Houzz is consistently identified as a top vertical-specific citation source for design/remodeling in qualitative cross-vertical rankings. No published study has measured an exact "Best of Houzz lifts citation rate by X%" figure at the per-contractor scale. Treat Houzz Pro as a near-mandatory directory presence for design-build firms — but the precise per-contractor lift has not been measured.

Why is the contractor AI-citation surface so dominated by third-party content?

Per Metricus's home-services audit, lead-gen platforms have "10,000x more content from the platforms than from the contractor who actually does the work." This volume asymmetry is why Angi, Thumbtack, and Yelp dominate AI outputs even when individual contractor sites have higher domain authority. Cost-comparison editorial (Forbes Home, Bob Vila, This Old House, NerdWallet) further crowds out individual-contractor citations on cost-qualified prompts.

What should an agency do with this on Monday morning?

Don't fight the third-party-publisher dominance — feed it. Audit each client's Angi, Thumbtack, HomeAdvisor, BBB, BuildZoom, and Houzz presence; ship LocalBusiness schema flagging license, bond, insurance, and trade-association memberships; maintain rating discipline above SOCi's 4.3-star ChatGPT threshold. For project-qualified citations, push Houzz Pro portfolio depth and Best of Houzz Service award eligibility. Pitch trade-press placements (Pro Remodeler, JLC, Remodeling Magazine Big50) as a digital-PR pipeline.
