Conclusion
Web scraping for lead generation offers significant potential for scalability and efficiency, especially in a market like Bangladesh where digital information is rapidly growing. However, the risks of legal and ethical breaches are high if not handled carefully.
Always prioritize:
Legality: Adhere to Bangladeshi laws (IT Act, Copyright, Digital Security Act) and general data privacy principles.
Ethics: Respect website ToS, robots.txt, and user privacy. Do not overwhelm servers.
Quality: Focus on obtaining accurate and relevant data that can be effectively used for outreach.
For businesses operating in Bangladesh, a more responsible approach might be to leverage public, intended-for-sharing data from business directories and publicly available company information, rather than attempting to extract personal contact details from private profiles or copyrighted content. When in doubt, err on the side of caution or consult legal advice.
