FAQs
What is visitor identification software?
Visitor identification software, or B2B website visitor identification software, helps businesses track and identify their website visitors.
Without it, you gather only limited information about who’s on your website.
With visitor identification software, you know the companies who visit your site, the pages they visit, and how often. Using B2B intelligence data, you can access the website visitor’s org chart, identify decision makers’ contact information, and reach out to them.
Ultimately, visitor identification software gives you the information you need to reach out to prospects with a message that fits their buying activity.

How does ZoomInfo know a business’s IP address?
Zoominfo knows a business’s IP address by creating a link between the IP address and website domain.
Using B2B website visitor identification software, ZoomInfo can identify website visitors who would otherwise remain anonymous.
See the following prospecting scenario that combines B2B website visitor tracking with automated workflows: Identify Prospects Through Website Visitor Insights.
What are buying signals, and how do they work?
B2B website visitor identification works by creating a link between a remote worker’s IP address and their company domain when employees are not working in the office.
The website visitor tracking software does a reverse IP-address lookup to identify otherwise anonymous website visitors. The visitor tracking tool then matches the IP address to a company.
Whether a website visitor is working off-site at a Starbucks or from their home office, your website visitor identification software will recognize the visitor as “a company.”

How does Automatic Traffic Filtering improve data quality?
Only verified human visits from identified companies are included in your follow-up data. This means your sales and marketing teams can focus exclusively on real, high-intent prospects — not bots or false signals.
Will Automatic Traffic Filtering change what I see in my reports?
Yes - your Analytics Dashboard will now display two metrics: Company Traffic (Real People) and Automated Traffic (Bots). Combined, they represent your total identification strength, providing a complete picture of every visit to your site.
