The Complete Guide to Website Visitor Identification
Turn anonymous website traffic into qualified leads with person-level visitor identification
Every day, potential customers visit your website, browse your pages, and leave without ever filling out a form. In fact, 97% of website visitors remain completely anonymous. Website visitor identification technology changes this by revealing who these visitors are—their names, email addresses, companies, and more—giving you the power to reach out while interest is still high.

What is Website Visitor Identification?
Website visitor identification is technology that reveals the identity of anonymous website visitors. Unlike traditional analytics that show you aggregate traffic data, visitor identification connects browsing sessions to real individuals and companies. This enables sales and marketing teams to understand exactly who's interested in their products and reach out proactively.
- Identify individuals visiting your website, not just companies
- Capture contact information without requiring form submissions
- See what pages visitors view and how long they engage
- Get real-time alerts when high-value prospects visit
- Integrate identified leads directly into your CRM
How Website Visitor Identification Works
Modern visitor identification combines multiple data sources and techniques to match anonymous browsers to known contacts. When someone visits your website, the identification platform analyzes various signals and cross-references them against extensive identity databases.
- A lightweight JavaScript snippet is added to your website
- The platform collects non-PII browser signals during visits
- These signals are matched against identity resolution databases
- When a match is found, contact details are returned
- Data flows into your CRM, marketing tools, or Slack in real-time
Company-Level vs Person-Level Identification
There's a crucial distinction between company-level and person-level identification. Legacy tools use IP address lookups to identify which companies visit—but that only tells you 'someone from Acme Corp visited.' Person-level identification goes further, telling you 'Sarah Chen, VP of Marketing at Acme Corp, viewed your pricing page three times this week.'
- Company-level: Identifies organizations via IP lookup (limited by remote work)
- Person-level: Identifies individuals with names, emails, and job titles
- Person-level enables immediate, personalized outreach
- Company-level requires additional research to find the right contact
- Person-level typically achieves 3x higher response rates

Frequently Asked Questions
What is website visitor identification?
Website visitor identification is technology that reveals who visits your website by matching anonymous browsing sessions to real individuals. It provides contact details like names, emails, and job titles for people who browse your site without filling out forms.
How does website visitor identification work?
Visitor identification works by adding a JavaScript snippet to your website that collects browser signals. These signals are matched against identity resolution databases to identify visitors. When a match is found, contact details are delivered to your CRM or notification channels.
Is website visitor identification legal?
Yes, when implemented properly. B2B visitor identification operates under legitimate interest provisions in GDPR and similar regulations. Reputable providers maintain compliance programs, honor opt-outs, and only process business contact data. Always choose a compliant provider and be transparent in your privacy policy.
What's the difference between company and person-level identification?
Company-level identification uses IP lookup to identify which organizations visit, but doesn't tell you who specifically. Person-level identification reveals the actual individual—their name, email, and job title—enabling direct outreach without additional research.
What percentage of website visitors can be identified?
Identification rates vary by tool and traffic composition. Company-level tools typically identify 10-20% of traffic. Person-level tools like Bullseye can identify up to 40% of visitors, with higher rates for returning visitors and US-based traffic.
How is visitor identification different from Google Analytics?
Google Analytics shows aggregate traffic data—pageviews, sessions, and demographics—but doesn't identify individuals. Visitor identification reveals who specific visitors are, enabling direct sales outreach and personalized marketing based on individual behavior.
