Web Scraping and Data Extraction

As a data extraction specialist, I‘ve implemented numerous scraping solutions across e-commerce platforms. Here‘s what works:

Structured Data Collection
- Product information
- Pricing data
- Inventory levels
- Customer reviews
- Competitor analysis

Advanced Scraping Techniques

# Sample scraping architecture
class EcommerceScraperConfig:
    headers = {‘User-Agent‘: ‘Mozilla/5.0...‘}
    proxy_rotation = True
    rate_limiting = 1.5  # seconds
    retry_attempts = 3

Data Quality Assurance
- Validation protocols
- Deduplication
- Data cleaning
- Format standardization
