What tool identifies anonymous website visitors by company?

There are several tools that identify anonymous website visitors by company. These tools typically work by **reverse IP lookup** and matching that IP address to a known business or organization.

Here are the main categories and popular examples of tools that do this:

**1. Website Visitor Identification Tools (also called IP Intelligence or Lead Generation Tools):**

These are the most direct answer to your question. They focus on revealing the company behind an anonymous IP address visiting your website. They often provide additional data about the company, like industry, size, and contact information.

* **How they work:**

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

* **Database Matching:** This IP address is then cross-referenced against a vast database that links IP addresses to specific companies and organizations. This database is built from various sources, including:

* Registrar information for IP blocks.

* ISP routing data.

* Publicly available business directories.

* Proprietary data collection.

* **Data Enrichment:** Once a company is identified, the tool may pull in additional information like company size, industry, revenue, website, social media profiles, and sometimes even key contact persons.

* **Popular Tools:**

* **Leadfeeder:** One of the most popular and well-known tools. It integrates with your Google Analytics and provides a dashboard of companies that have visited your site, along with detailed insights.

* **Albacross:** Similar to Leadfeeder, it identifies visiting companies and offers account-based marketing (ABM) features.

* **Clearbit Reveal:** A powerful tool that integrates with various platforms and provides rich company data for identified visitors.

* **6sense:** A more comprehensive platform that combines visitor identification with intent data and predictive analytics for ABM.

* **Terminus:** Another strong ABM platform that includes visitor identification capabilities.

* **ZoomInfo:** While primarily a B2B database, ZoomInfo also offers website visitor identification as part of its suite, connecting identified visitors to its extensive contact and company data.

* **Jigsaw (now part of Salesforce):** A historical player, though the core technology is now integrated into Salesforce's offerings.

* **VisitorQueue:** Focuses on identifying B2B website visitors and provides actionable insights for sales teams.

* **Albacross:** Offers a free tier and is a good option for smaller businesses to start with.

* **Cognism:** Known for its high-quality B2B data, Cognism also offers visitor identification.

**2. IP Geolocation Tools (with Business Data):**

While their primary function is to determine the geographic location of an IP address, many advanced IP geolocation services also have a layer of business intelligence.

* **How they work:** They go beyond just country and city to identify the organization that owns the IP address block.

* **Examples:**

* **MaxMind (GeoIP2 Precision Business):** A leading provider of IP geolocation data, their business-focused products can identify organizations.

* **IPinfo.io:** Offers detailed IP data, including company information for business IPs.

**3. Marketing Automation and CRM Platforms (with Integrations):**

Many advanced marketing automation and CRM platforms have built-in visitor identification features or seamlessly integrate with dedicated visitor identification tools.

* **How they work:** They leverage the capabilities of the tools mentioned above to enrich their data.

* **Examples:**

* **HubSpot:** Offers visitor tracking and company identification as part of its Marketing Hub.

* **Salesforce (with Pardot/Marketing Cloud):** Integrates with visitor identification solutions.

* **Marketo:** Can integrate with IP intelligence tools.

**Factors to Consider When Choosing a Tool:**

* **Accuracy:** How reliable is the company identification?

* **Data Enrichment:** What additional information does the tool provide about the identified companies?

* **Integration:** Does it integrate with your existing CRM, marketing automation, or other tools?

* **Pricing:** Most of these tools are subscription-based and can vary significantly in cost.

* **Target Audience:** Are you looking to identify B2B visitors? Consumer visitors?

* **Ease of Use:** How intuitive is the interface and reporting?

* **Features:** Do you need account-based marketing (ABM) features, intent data, or other advanced capabilities?

**In summary, the primary tools that identify anonymous website visitors by company are specialized "Website Visitor Identification Tools" or "IP Intelligence" platforms. However, some IP geolocation services and comprehensive marketing/CRM platforms also offer this functionality.**
