If you're building your own contractor lead pipeline, you need to know where to find them. Yelp, Google Places, and Thumbtack are the three biggest directories. But which has the most contractors, the best quality data, and the freshest information?
The Directory Landscape in 2026
Contractor discovery has fragmented. There's no single source of truth anymore. Your plumber might be on Google, your electrician on Yelp, your general contractor on all three. If you're serious about coverage, you need data from all three.
But they're not equivalent. Coverage, data quality, recency, and pricing vary wildly. Here's what you need to know.
Google Places (Google Maps + Google Search)
Coverage
Contractor count (estimate): 8–10 million in the US
Google Places is the largest directory by far. Almost every contractor has a Google Business Profile because it's where homeowners search first ("plumber near me" = Google Maps). Even contractors who don't actively update it often have a profile.
Best coverage for: All trades, all regions. If you're searching nationally, Google is the widest net.
Data Quality
Contact info completeness: 85–90%. Most profiles have a phone number. Websites and emails less reliable (40–50% have websites). Address usually present (80%+).
Review quality: Mixed. Google reviews attract both detailed, legitimate reviews AND review-bombers and fake reviews. Validation is weaker than Yelp's. Fake reviews are more common on Google than Yelp.
Business information accuracy: Moderate. Hours change frequently but profiles aren't always updated. Categories are broad ("General Contractor," "Home Improvement"). Service area info sparse.
Verdict: High volume, medium quality. Good for broad searches, but expect noise.
Data Freshness
Review recency: Highly variable. Active contractors get daily reviews; inactive ones may have nothing for 6+ months.
Profile updates: Some contractors update constantly, others not at all. No enforcement of freshness.
New contractors: Fast — new Google Business Profiles appear within days.
Verdict: You get a mix of fresh and stale. Filtering by recency (reviews <90 days) is essential.
Access & Cost
How to get the data: Google Maps API (paid), web scraping, third-party data providers (expensive).
Cost: Free if you use Google Maps API directly (up to limits), $0.50–$5 per lead from data brokers.
Yelp
Coverage
Contractor count (estimate): 1.5–2 million in the US
Yelp is much smaller than Google but more curated. Not every contractor is on Yelp; those who are usually take it seriously. Good coverage of established, legitimate contractors. Gaps in rural areas and newer trades.
Best coverage for: Established contractors in metro areas (NYC, LA, Chicago, Austin, etc.). Niche if you're in rural regions.
Data Quality
Contact info completeness: 95%+. Yelp requires phone numbers and addresses. Website and email less common (30–40%). Address almost always present.
Review quality: High. Yelp has industry-leading review validation. Flags fake reviews, review-bombers, and suspicious patterns. Reviews are more trustworthy than Google.
Business information accuracy: Very good. Yelp forces contractors to fill in service categories, areas served, hours. Data is more standardized than Google.
Verdict: Lower volume, higher quality. Better for targeted searches in urban areas.
Data Freshness
Review recency: Good. Established contractors get regular reviews.
Profile updates: Contractors who care about Yelp keep profiles updated. Those who don't are stale.
New contractors: Slower than Google — takes 2–4 weeks for new Yelp pages to appear.
Verdict: Generally fresher than Google, but slower to pick up new contractors.
Access & Cost
How to get the data: Yelp Fusion API (free with rate limits), web scraping, data providers.
Cost: Free API tier (limited), $0.50–$3 per lead from data brokers.
Thumbtack
Coverage
Contractor count (estimate): 400k–500k in the US
Thumbtack is the smallest of the three, but every contractor on Thumbtack is actively soliciting work. They pay to be there. This is a major difference from Google and Yelp where contractors might be passive.
Best coverage for: Contractors actively bidding for work. Higher intent = higher quality. Weaker in rural areas.
Data Quality
Contact info completeness: 95%+. Thumbtack requires phone, verified address, and usually a website to be competitive.
Review quality: Very high. Reviews only come from completed Thumbtack jobs. No fake reviews possible. Most reviewed contractors on Thumbtack are legitimate.
Business information accuracy: Excellent. Thumbtack forces detailed service profiles, service area info, and pricing. Data is the most standardized of the three.
Verdict: Smallest volume, highest quality. Best for precision targeting of active contractors.
Data Freshness
Review recency: Fresh. Only active contractors stay on Thumbtack; inactive ones fall out naturally.
Profile updates: Almost all Thumbtack profiles are current (contractors maintain them to stay competitive).
New contractors: Slower onboarding due to verification, but faster steady-state updates.
Verdict: Freshest data of the three, but smallest overall population.
Access & Cost
How to get the data: Web scraping (Thumbtack blocks APIs), data providers.
Cost: $1–5 per lead from data providers (most expensive).
Comparison Table
| Dimension | Google Places | Yelp | Thumbtack |
|---|---|---|---|
| Contractor Count | 8–10M | 1.5–2M | 400–500K |
| Data Quality | Medium | High | Very High |
| Contact Info | 85–90% | 95%+ | 95%+ |
| Review Quality | Medium (fake reviews) | High (validated) | Very High (job-based) |
| Freshness | Variable | Good | Excellent |
| Access Cost | Free–$5/lead | Free–$3/lead | $1–5/lead |
Which One Should You Use?
If you want coverage: Google Places. You'll find the most contractors, but expect more noise. Filter aggressively (recent reviews, verified address, quality signals).
If you want quality: Yelp + Thumbtack. More contractors, better data, higher confidence. Start here and supplement with Google.
If you want active contractors right now: Thumbtack. Smallest list, but highest intent. Everyone on Thumbtack is actively seeking work.
The Smart Play: Use All Three
The most sophisticated contractors and agencies use all three directories:
- Primary source (Yelp + Thumbtack): 1.5M + 400K = 1.9M high-quality contractors
- Secondary source (Google): 8M contractors to fill gaps, especially in underserved regions
- Deduplication: Match by phone number and business name to avoid calling the same person twice
This approach gives you the largest possible pool of quality leads.
How LeadTrawl Handles It
LeadTrawl pulls from all three sources, deduplicates by phone number and domain, and returns a unified, scored list. You run one campaign and get contractors from Yelp, Google, and Thumbtack in a single export.
Instead of managing three separate data sources, scoring by hand, and checking for duplicates, you get pre-deduplicated, pre-scored leads ready to call.
The Bottom Line
In 2026, there is no single "best" contractor directory. Google has volume, Yelp has quality, Thumbtack has intent. The contractors building sustainable pipelines use all three, deduplicate, score, and call the best ones first.
If you're serious about owning your lead pipeline, you need data from all three sources. Relying on one is leaving 60–80% of contractors on the table.
