Website Visitor Identification reveals the companies browsing a site and scores their engagement for sales follow-up.
Website Visitor Identification matches traffic on tracked domains against Lusha's company profiles, returns each visiting company with its firmographics, and scores every visitor from 1 to 100 as cold, warm, or hot. Identification is company-level rather than person-level, and the engagement score is built from session depth, unique visitors, time on site, high-intent page views, and how recently the company returned. The result is a ranked list of accounts showing buying interest before any form is filled in.
Each identified company is cross-referenced against Lusha's contact database so the relevant decision-makers surface with verified emails and direct dials, and hot accounts can be routed straight into Slack alerts, CRM updates, or outreach sequences. The capability is available in the Lusha workspace, through the Website Visits API, through native Salesforce and HubSpot integrations, and inside Claude, ChatGPT, and other MCP clients.
