When you search for website visitor identification software, you'll encounter two very different categories of tool — and the difference between them determines whether you get a 3x or a 30x return on the investment. The two categories are company-level identification and person-level identification, and most buyers don't understand the distinction until they've already committed to the wrong one.
Company-Level Identification: What You Get
Company-level identification tells you the organisation that visited your website. You see 'Acme Corp visited your pricing page 3 times this week.' You know the company name, the industry, the approximate size, and often their location.
This is how the majority of legacy tools work — Dealfront (formerly Leadfeeder), Albacross, Lead Forensics, Snitcher, and Clearbit Reveal all operate primarily at the company level. They match the visitor's IP address to a corporate IP range in their database and return the company name.
Company-level data is useful but incomplete. You know Acme Corp is interested — but Acme Corp might have 500 employees. Which one visited? Which one should you contact? You still have to manually research contacts, find the right decision-maker, and guess at the right outreach approach.
Person-Level Identification: What You Get
Person-level identification tells you the individual who visited. You see: 'Sarah Johnson, VP of Sales at Acme Corp, visited your pricing page — here's her verified email and LinkedIn profile.' You know exactly who to contact, and you can reach them immediately.
This is what Happierleads and RB2B specialise in. Instead of matching an IP to a company, person-level tools match visitor behaviour to an identity graph that includes millions of verified individuals — name, title, company, email, and social profiles.
The difference in actionability is enormous. With company-level data, your workflow is: identify company → research contacts → find the right person → reach out. With person-level data, your workflow is: identify person → reach out. The former takes 20–30 minutes per lead. The latter takes 2 minutes.
The Coverage Trade-Off
Person-level identification is more powerful, but it identifies fewer visitors — typically 30–50% of B2B traffic vs 60–70% for company-level. This is because person-level ID requires matching a visitor to a specific individual in a data graph, which requires more data points than simply matching an IP to a corporate IP range.
The practical implication: if you have 1,000 B2B visitors per month, a company-level tool might identify 600–700 companies, while a person-level tool might identify 300–400 specific individuals. On raw volume, company-level wins. On actionability, person-level wins decisively — because identified individuals can be contacted directly, while identified companies still require manual research.
Geographic Coverage: The Critical Variable
Person-level identification is also more geography-dependent than company-level. Company IP ranges are fairly global — most large companies have registered IPs regardless of where they operate. Person-level identity graphs are much more developed in the US than in Europe, Asia, or other markets.
This is why RB2B — a person-level tool — identifies US visitors only. Their identity graph has excellent US coverage but limited non-US data. Happierleads has invested in building a global identity graph that covers 174+ countries, including full EU and UK coverage — making it the only person-level tool that works for companies with non-US audiences.
Which Should You Choose?
Here's the simple framework:
- Use person-level if: Your ACV is $1K+ (high enough to justify direct outreach), you have a dedicated person or team doing outreach, and your traffic comes from markets where person-level tools have coverage (US, EU, UK, APAC). Person-level identification at $299/mo will almost always outperform company-level at $99/mo when the economics work.
- Use company-level if: You're selling into a very niche market where you already know all the companies (ABM), your team doesn't have capacity for individual outreach, or your traffic volume is very high and you need to prioritise by account rather than by individual.
- The false economy: Many B2B teams choose company-level tools because they're cheaper or better known. But if they're spending 20+ minutes per lead doing manual research that a person-level tool would eliminate, the cost savings disappear fast. At $50/hour for a SDR's time, 5 leads researched manually costs $83 — more than a month of the tool difference.
The Workflow Difference in Practice
Here's what the actual day-to-day looks like for a sales rep using each type of tool:
Company-level workflow: Monday morning, you open your visitor identification dashboard. You see 12 companies visited your pricing page this week. You manually look up each company on LinkedIn. For each, you find 2–3 relevant contacts. You export to a Google Sheet. You spend the rest of Monday building personalised emails for 8 of the 12. You send Thursday. Total time: 4–5 hours per week.
Person-level workflow: Monday morning, you open Happierleads. You see 8 specific people visited your pricing page this week — names, titles, verified emails, LinkedIn profiles all shown. You filter by ICP (e.g., VP+ at 50–500 employee companies). 5 qualify. You use the built-in Inbox Engine to trigger your 'warm visitor' email sequence for all 5. Total time: 20 minutes.
The compounding effect over a quarter is substantial. More outreach, more replies, more meetings — from the same traffic, with less manual effort.
The Bottom Line
Company-level identification was the best available option for most of the 2010s. Person-level identification is the category winner for the 2020s — and it's now globally available, not just in the US.
If you're evaluating visitor identification tools, start with the question: do I want to know which company visited, or do I want to know which person visited? The answer determines your entire shortlist. Try Happierleads person-level identification free for 7 days →
