1. Overview of the 4 Major Business Directory Providers
When engineering a modern B2B lead extraction system, choosing the right underlying data source determines contact quality, cost, and completeness. Here is an architectural breakdown of the four major platforms:
2. Coverage & Data Accuracy Comparison
1. Google Places API
Pros: Highest global coverage, freshest telephone numbers, authentic user reviews, and active status tracking.
Cons: Strict API rate limits, expensive pricing tiers ($17–$32 per 1,000 requests on raw Google Cloud).
2. OpenStreetMap (OSM) / Overpass
Pros: 100% open-access, zero licensing fees, excellent geographic tagging for physical shops, factories, and buildings.
Cons: Lower fill rate for telephone numbers and websites compared to Google.
3. Foursquare Places
Pros: Premium venue metadata, popular in North America, Europe, and Southeast Asia for dining, entertainment, and corporate offices.
Cons: Lower coverage for industrial and B2B manufacturing companies.
4. MapMyIndia (Mappls)
Pros: Unrivaled hyper-local address accuracy for India, covering industrial corridors, SEZ zones, and village-level POIs.
Cons: Limited to the Indian subcontinent.
3. Cost, Rate Limits & Reliability
Running raw API queries on Google Cloud can quickly cost hundreds of dollars each month. By using an aggregator like LeadGen Pro, users get access to pre-authenticated enterprise pipelines across all 4 providers starting at a fraction of raw API costs.
4. Why Hybrid Multi-Source Scraping Wins
Instead of locking into one vendor, a multi-source engine queries OpenStreetMap and Foursquare for baseline coordinates, cross-references with Google Places for ratings and phone numbers, and taps MapMyIndia for verified Indian addresses. This hybrid approach produces up to 3x higher contact discovery rates.
5. Summary & Recommendation
For most sales and prospecting teams, using a platform with multi-source switching built in gives you maximum flexibility and cost efficiency.
