Visitor Identification tools reveal which companies are visiting your website — deanonymizing IP-based traffic into firmographic data and matching it against CRM and target account lists to surface high-intent accounts for sales follow-up. Core capabilities include IP-to-company resolution, firmographic enrichment of anonymous visitors, CRM and target account list matching, page-level engagement scoring, real-time alerts for high-value visits, and integration with CRM, ABM, and outreach tools. The category spans website visitor identification platforms (Clearbit Reveal, RB2B, Leadfeeder/Dealfront, Warmly, 6sense web identification) and identification features within broader ABM platforms.
