What tool identifies anonymous website visitors by company?

The tools that identify anonymous website visitors by company are generally called **website visitor identification tools**, **B2B visitor tracking tools**, or **IP intelligence tools**.

These tools work by capturing the IP address of a website visitor and then cross-referencing it with a proprietary database that maps IP ranges to specific companies and organizations.

Here are some popular examples:

1. **Leadfeeder:** One of the most well-known tools in this category. It integrates with Google Analytics and identifies companies visiting your site, showing you their browsing behavior.

2. **Clearbit Reveal:** Part of the Clearbit platform, it identifies companies visiting your website and enriches their profiles with firmographic data.

3. **Albacross:** Similar to Leadfeeder, it identifies companies visiting your site and provides contact information for key decision-makers within those companies.

4. **ZoomInfo (formerly Kompany):** While ZoomInfo is primarily a B2B data and intelligence platform, it offers features that can identify companies visiting your website and provide detailed information about them.

5. **Snitcher:** Another tool focused on identifying companies visiting your website and providing insights into their behavior.

6. **GoSquared:** Offers real-time analytics and visitor identification, including company names.

**How they generally work:**

* **IP Address Capture:** When a visitor lands on your site, the tool captures their IP address.

* **Database Lookup:** This IP address is then compared against a vast database that links IP ranges to specific organizations (companies, universities, government agencies, etc.).

* **Company Identification:** If a match is found, the tool identifies the company.

* **Data Enrichment:** Many tools then enrich this information with firmographic data (industry, size, location, revenue) and sometimes even contact details for potential leads within that company.

* **Behavioral Tracking:** They also track which pages the identified company viewed, how long they stayed, and other engagement metrics.

**Important Considerations:**

* **B2B Focus:** These tools are most effective for B2B websites, as visitors are more likely to be browsing from a corporate network with a static, identifiable IP address.

* **Accuracy:** They are not 100% accurate. They cannot identify individuals, only the company. Visitors using home internet, mobile data, VPNs, or generic ISP IPs will often not be identified by company.

* **Privacy:** They identify the *company*, not the individual person. This is generally compliant with privacy regulations like GDPR and CCPA, as long as you're transparent about your data collection practices.

* **Actionability:** Knowing a company visited is the first step. You still need a strategy to engage with them (e.g., sales outreach, targeted advertising).
