Every website visitor identification tool does one of two things: it identifies the company a visitor works for, or it identifies the person. The difference decides whether the tool is useful to your business at all. This guide explains how each works and which one fits B2B and B2C businesses.
Key Takeaways
- Company-level identification matches a visit to a business, usually from its network. It doesn’t name the person.
- Person-level identification matches a visit to an individual contact record.
- B2B firms selling to companies can get value from either; businesses selling to individuals need person-level data.
- Person-level data comes with more responsibility: disclosure, opt-outs and outreach rules.
How company-level identification works
When someone visits from a corporate network, their connection can often be traced to the company that owns it. Company-level tools use that, plus other signals, to tell you which businesses visited and which pages they viewed. Many add firmographic data like industry, size and location.
What it’s good for: B2B firms that sell to companies and want to know which accounts are showing interest, so a salesperson can reach the right contacts.
Where it falls short: it can’t tell you who the visitor was, and it doesn’t work for people browsing from home or a phone, where the network belongs to an internet or mobile provider. That’s most consumer traffic.
How person-level identification works
Person-level tools match a visit to an individual using an identity network built from consented data sources. When there’s a confident match, you get a contact record: name, email, phone, company and location where available, along with the pages the person viewed.
What it’s good for: any business that sells to people, and B2B firms that want to know exactly who on a buying team is researching them.
Where it falls short: not every visitor can be matched, and the data comes with privacy and outreach obligations.
Side by side
| Company-level | Person-level | |
|---|---|---|
| Identifies | The business behind a visit | The individual visitor |
| Typical data | Company name, industry, size, location, pages viewed | Name, email, phone, company, location, pages viewed |
| Works on home and mobile traffic | Rarely | Often |
| Best for | B2B account-based selling | B2C and B2B businesses that want named contacts |
| Follow-up | Research the account, then find contacts | Contact the person directly |
| Privacy load | Lighter | Heavier: disclosure, opt-outs, outreach rules |
Which one does your business need?
You sell to companies (B2B): company-level identification shows which accounts are interested. Person-level identification goes further and shows who. Many B2B firms start with company-level and add person-level as their follow-up matures.
You sell to people (B2C): you need person-level identification. A roofer, a dealership or a law firm gets little from knowing a visitor’s internet provider. Look for a provider whose data covers consumers, not only business professionals, since many person-level tools were built for B2B.
You sell to both: person-level identification with company data included where it exists covers both.
Doing person-level identification responsibly
Because person-level identification produces contact records, it carries more responsibility:
- Disclose visitor identification in your privacy policy.
- Honor opt-out and do-not-contact requests across your data.
- Follow CAN-SPAM for email and the TCPA for calls and texts, which generally requires consent for marketing calls and texts to mobile phones.
- Keep identification off pages where people submit sensitive information.

FAQ
Is person-level visitor identification more accurate than company-level?
They measure different things. Company-level tools often match a larger share of B2B traffic to a business; person-level tools match fewer visits overall but give you a named contact. The right measure is which one produces conversations and customers for your business.
Does person-level identification work for B2B?
Yes. It shows which individuals at a company are researching you, which helps sales teams reach the right person instead of guessing.
Why do most visitor identification tools focus on B2B?
The category grew out of B2B sales and account-based marketing, where company-level data alone was valuable. Consumer-focused, person-level identification is newer and less widely offered.
Conclusion
If you sell to companies, company-level identification is a useful start. If you sell to people, you need person-level identification.
