FAQs

Q: How do website visitor identification tools work?

A: These tools use various methods including reverse IP lookup, browser fingerprinting, cookie tracking, and cross-device matching to identify anonymous visitors. They match this data against proprietary databases to reveal company and contact information.

Q: Is visitor identification legal and compliant with privacy laws?

A: Most reputable platforms like OpenSend's Connect tool are GDPR and CCPA compliant. However, compliance varies by platform and implementation, so always review privacy policies and ensure proper consent mechanisms are in place.

A: ROI varies significantly but successful implementations often see 5-20x returns. OpenSend customers regularly report 8-20x ROAS, with some achieving significant incremental revenue within 30 days.

Q: Can these tools identify individual visitors or just companies?
