Website Visitor Identification

Revealing which companies, or sometimes which people, visit a website, often via reverse IP lookup, to prioritize sales outreach.

Short answer

Website visitor identification is the process of revealing which companies, or sometimes which people, visit a website, often through reverse IP lookup, to prioritize sales outreach. It turns anonymous traffic into account-level signals for B2B teams. Accuracy varies, and identifying individuals raises privacy and consent considerations under laws such as GDPR.
