Our Client

A major national data provider offering:

• business leads
• local service directories
• telemarketing-ready lists
• location-intelligence datasets

Their customers include:

• banks
• insurance firms
• field service companies
• enterprise sales teams
• logistics & mapping platforms

They relied heavily on YellowPages as a primary input source — but the raw scraped data was messy, fragmented, and inconsistent.

To stay competitive, they needed a clean, enriched, de-duplicated, and production-ready YellowPages dataset.

The Challenge

The client’s internal extraction attempts failed due to the complexity and volume of YellowPages listings.

1. Messy and inconsistent HTML structure

YellowPages has:

• varied page layouts
• inconsistent fields
• hidden elements
• duplicate entries across categories

This caused inaccurate or missing data.

2. Massive data volume: 12+ million pages

Their older scripts couldn’t handle:

• concurrency
• proxy rotation
• retries
• pagination depth

Extraction frequently broke.

3. High duplication rates

Businesses appear across:

• multiple categories
• keyword searches
• nearby areas
• sponsored listings

This led to inflated record counts.

4. No standardized schema

Key fields like:

• business names
• addresses
• phone numbers
• categories

were formatted differently in every region and category.

5. Accuracy expectations were extremely high

The client needed:

• perfect address cleanliness
• verified phone numbers
• correct business status
• accurate geocoding

Low-quality datasets could damage customer trust.

The Solution

Actowiz Solutions developed a full-scale YellowPages Data Pipeline, offering extraction, cleaning, validation, and structuring as a unified service.

1. Industrial-grade crawling engine for YellowPages

We built dedicated crawlers with:

• rotating residential & ISP proxies
• adaptive throttling
• dynamic HTML parsing
• auto-detection for site structure changes
• retry & re-scan workflows

This enabled stable extraction at national scale.

2. Deep data extraction from all listing layers

Each business record was extracted with over 60 enriched attributes, including:

• business name
• full address
• phone numbers
• website
• category
• services offered
• rating & reviews (when available)
• hours of operation
• latitude & longitude
• listing type (organic vs sponsored)

3. ML-based deduplication engine

Actowiz cleaned millions of overlapping listings using:

• fuzzy text matching
• address normalization
• phone number reconciliation
• category similarity scoring

Duplicate reduction accuracy reached 96%.

4. Address normalization & geocoding

Addresses were standardized into:

• street
• district
• state
• zipcode

Using USPS-style formatting + geocoding APIs.

5. Business status verification

Actowiz verified:

• open businesses
• permanently closed entries
• relocated locations
• phone number validity

Dead leads were removed from the dataset.

6. Structured data delivered in client-ready format

We provided:

• CSV
• JSON
• PostgreSQL dumps
• API access

All mapped into one clean, unified schema.

The Impact

The client saw a dramatic improvement in the usability and market readiness of their data products.

1. 12 million fragmented listings → 3.5 million clean records

A completely transformed dataset, with all duplicates eliminated.

2. 60+ structured fields per business

Perfect for segmentation, targeting, analytics, and CRM systems.

3. Lead accuracy increased by 89%

Higher conversion rates for marketing & outbound sales customers.

4. Dataset quality became a competitive advantage

Their new dataset outperformed competitors in:

• completeness
• consistency
• accuracy
• freshness

5. Faster time-to-market for new data products

The cleaned dataset enabled:

• geospatial products
• category-level intelligence
• local market analysis
• small business insights

6. Long-term partnership with Actowiz Solutions

The client now receives:

• monthly refreshes
• incremental updates
• new directory integrations
• alerting for structural changes

Their entire business listings ecosystem is now automated.
