Best Website Visitor Identification Tools
Compare tools that reveal who's visiting your website
Website visitor identification tools turn anonymous traffic into actionable leads. They reveal the companies and individuals visiting your site—without forms. With 97% of visitors leaving anonymously, these tools capture demand you'd otherwise lose. This guide compares the top solutions to help you choose the right one.
What to Look For
Person-Level vs Company-Level
Company-level tools show which businesses visit. Person-level tools like Bullseye reveal actual individuals with emails and job titles—far more actionable for sales outreach.
Identification Rate
What percentage of visitors can be identified? Rates vary from 10% (IP-based) to 40%+ (person-level). Higher rates = more leads from the same traffic.
Data Quality
Are emails verified and deliverable? Is company data accurate? Bad data wastes time and damages sender reputation.
Integrations
Does it connect to your CRM, Slack, and marketing tools? Native integrations ensure data flows automatically into your workflows.
Compliance
Is the provider compliant with GDPR, CCPA, and other regulations? B2B visitor identification should operate under legitimate interest provisions.
Pricing Transparency
Some tools have opaque enterprise pricing. Look for clear, published pricing that scales with your needs.
