How I Built an AI-Powered Google Maps Scraper for Lead Generation

The Problem

Every sales team needs local business leads, but manually searching Google Maps and copying data is painfully slow. I needed a way to extract hundreds of leads in seconds.

What I Built

I built GMapsScraper AI — a tool thatuses AI to extract business data from Google Maps at scale.

Tech stack:

  • Next.js 14 (frontend)
  • Cloudflare Workers (deployment)
  • Supabase (auth + database)
  • Go-based scraper (backend on Google Cloud Run)

How It Works

  1. User enters a keyword + location (e.g. "dentist, New York")
  2. Backend spins up a headless browser to crawl Google Maps
  3. AI processes and structures the raw data
  4. Returns clean results: name, phone, email, website, rating, reviews
  5. One-click CSV export for CRM import

Key Technical Challenges

Rate limiting — Google Maps aggressively blocks automated requests. Solution: rotating proxies + randomized delays + browser fingerprint rotation.

Data accuracy — Raw scraped data is messy. Used AI to normalize phone formats, validate addresses, and deduplicate results.

Speed — Users expect results in seconds. Implemented parallel scraping with a job queue system to handle concurrent requests.

Results

  • 200+ leads extracted per search
  • Average response time under 30 seconds
  • Supporting 18 languages and global locations

Nice write-up! Curious about the proxy rotation strategy — are you using residential proxies or datacenter? I've been hitting rate limits with datacenter IPs when scraping at scale.

Started with datacenter but switched to a mix of residential + mobile proxies. The key is randomizing request intervals between 2-5 seconds and rotating user agents. Haven't been blocked since.

Would be cool to have a Zapier integration so I can auto-trigger outreach sequences when new leads are exported. Any plans for that?

Good idea! We're considering Zapier and Make integrations. For now the CSV → HubSpot import workflow works well but direct API integration is on the roadmap.
