TL;DR
- Person-level identification and company-level identification are different products sold under the same category name. Person-level tools return a named individual. Company-level tools return an account. Buying the wrong one is the most common mistake we see.
- RB2B is the strongest fit for person-level identification of US traffic on a small budget, at $149 to $199 per month. It does not cover visitors outside the United States.
- Vector is the strongest fit when you want identified contacts pushed into paid ad audiences, starting at $399 per month and scaling to $999.
- Leadfeeder is the strongest fit for GDPR-sensitive European company-level identification, with a genuine free tier and paid plans from roughly $99 per month.
- Match rates are the number that matters, and vendor claims vary from 15% to 80%. Read the section on how match rate is calculated before you compare quotes.

How visitor identification actually works
Every tool in this category does the same three things in sequence. It drops a pixel on your site, it observes signals from the visiting device and network, and it matches those signals against an identity database.
The differences sit entirely in step three. Company-level tools perform IP-to-company resolution, mapping the visitor's network to a business. This is mature, well understood, and works across most of the world. Person-level tools attempt to resolve the individual, which requires a much larger identity graph built from cookie syncs, form fills, and third-party data partnerships. That graph is dense in the United States and thin almost everywhere else, which is why nearly every person-level vendor is US-only or US-heavy.
This single technical fact explains most of the pricing and coverage differences below.
Comparison table: match rate, resolution level, and price

The 7 tools reviewed
1. RB2B
Best for: US-focused teams that want a named person and a LinkedIn URL in Slack within seconds, without an annual contract.
RB2B is the clearest expression of what person-level identification is for. It pushes the LinkedIn profile of an identified visitor straight into Slack. There is no dashboard ceremony and no six-week onboarding. Over 100,000 websites run the pixel, and the company holds SOC 2 Type II certification.
Pricing: Free at 150 monthly resolutions with company-level identification only. Starter at $79 per month for 300 resolutions with LinkedIn URLs. Pro at $149 per month for 600 resolutions, adding business email addresses and full integrations. Pro+ at $199 per month with premium resolution. All plans include unlimited users, which is unusual in this category.
Where it falls short: RB2B identifies US visitors only. If a meaningful share of your traffic is European or APAC, those visitors are invisible. Reviewers on G2 consistently note that the tool captures a fraction of total traffic, which is true of every tool here but felt more sharply when the geographic filter is applied first. The RB2B and Demandbase partnership claims 70 to 80% resolution, but that figure describes the combined product, not standalone RB2B.
Verdict: For a US-traffic B2B site, the price to value ratio is the strongest in the category. For anyone selling into Europe, it solves a fraction of the problem.
2. Vector
Best for: Teams that want identified contacts to become an addressable ad audience rather than an SDR task.
Vector splits into two products. Reveal identifies visitors by name, title, and company. Target syncs those contacts into LinkedIn, Google, and Meta ad audiences. That second product is the genuine differentiator, because most competitors stop at identification and leave activation to you.
Pricing: Reveal is usage-based on a monthly commitment: $399 per month for 2,500 identified visitors, $599 for 5,000, $799 for 7,500, and $999 for 10,000. Custom above that. There is a 14-day free trial. Target requires an annual contract starting at $3,000 per month, or $36,000 per year minimum.
Where it falls short: Vector publishes a 15 to 30% identification rate, which is honest and also considerably below what some competitors imply. The Target annual minimum is a serious commitment for a mid-market team, and it cannot be bought month to month. Integration breadth is narrower than the incumbents.
Verdict: The strongest fit where paid media is already a major channel and the gap is audience precision rather than lead volume.
3. Warmly
Best for: Teams that want identification, on-site chat, and automated outbound from a single system.
Warmly bundles visitor identification with an AI chat agent and outbound sequencing. The pitch is workflow consolidation, and for teams currently running three tools to do this, that argument lands.
Pricing: A limited free tier exists. Paid plans start around $700 to $900 per month for the Business and Data Agent tiers, rising to $1,500 or more. All paid plans require annual contracts, putting the effective minimum commitment near $10,800 per year.
Where it falls short: The reported 15 to 25% match rate sits at the lower end of the category. Annual-only billing removes the ability to test on live traffic before committing. Note that Warmly has been acquired by HubSpot, so packaging and roadmap should be expected to shift toward the HubSpot ecosystem. Verify current terms before signing a multi-year deal.
Verdict: Strongest where the consolidation argument is real and the team is already committed to HubSpot.
4. Leadfeeder (formerly Dealfront)
Best for: European teams that need defensible GDPR posture and company-level identification with real CRM automation.
Dealfront rebranded to Leadfeeder on 24 March 2026, with no change to contracts or pricing. The product identifies companies rather than individuals, then uses a shared credit pool for contact enrichment, exports, and CRM syncs.
Pricing: A genuine free forever tier covers up to 100 identified companies per month with seven-day data retention and unlimited users. Paid plans start at $99 per month billed annually and scale with the number of companies identified. Capterra lists Activate at €369 per month and Scale at €599. Annual billing carries a 30% discount over monthly.
Where it falls short: Company-level only, so you still need to work out who at the account to contact. Credits are a shared pool across enrichment, export, and sync, which makes forecasting usage harder than a single-purpose meter.
Verdict: The most defensible choice for European traffic, and the free tier makes it the cheapest way to find out whether visitor identification produces anything useful for your site at all.
5. Albacross
Best for: European ABM teams that want intent segmentation layered on top of company identification.
Albacross is Stockholm-based, founded in 2014, and explicitly built around GDPR and CCPA compliance. It adds AI-powered visitor segmentation that groups accounts by likelihood to convert, which is a genuine step beyond a raw list of company names.
Pricing: No free plan, but a 14-day trial with no card required. Three published tiers, all annual: Starter at €59 per month, Professional at €149, and Organisation at €375. Monthly billing on Starter is €84.
Where it falls short: The credit allocations are the catch. Starter includes only 10 email credits and 5 phone credits per month, which is not usable for any real prospecting motion. API access, webhooks, and ABM features are add-ons even on the top plan. CRM support below the higher tiers is limited to Pipedrive.
Verdict: Reasonable for intent-led European ABM. The published entry price is not the price you will actually pay once credits are sized realistically.
6. Snitcher
Best for: Budget-conscious teams that want company-level identification and nothing else.
Snitcher occupies the low-cost end of company-level identification. It does one job, integrates with Google Analytics, and does not attempt to be a GTM platform.
Pricing: Low-cost monthly tiers with a free trial. Confirm current rates at purchase, as this segment reprices frequently.
Where it falls short: No person-level resolution, limited enrichment, and none of the orchestration that the larger platforms bundle. You will need a separate enrichment and sequencing layer.
Verdict: Fine as a first step to validate the category before spending real money.
7. Apollo.io
Best for: Teams already paying for Apollo that want basic visitor identification without adding a vendor.
Apollo includes website visitor identification within its broader prospecting platform. It is company-level, and it is convenient rather than best in class.
Pricing: Bundled into Apollo plans. Basic is $49 per user per month on annual billing, Professional $79, and Organization $119 with a three-seat minimum. Monthly billing runs roughly 15 to 25% higher.
Where it falls short: Identification is a secondary feature rather than the core product, and depth reflects that. Credits expire each billing cycle. Reported data accuracy across the wider Apollo database sits around 65 to 70% per G2 and Trustpilot reviews.
Verdict: Worth switching on if you already pay for Apollo. Not worth buying Apollo for.
Person-level vs company-level: which you actually need
The honest answer depends on your deal size and your sales motion, not on which sounds more advanced.
Person-level identification is worth paying for when your average contract value justifies a rep researching and contacting a single named individual off the back of one page view. Below roughly $20,000 ACV, the economics rarely hold, because the rep time per identified person exceeds the expected value.
Company-level identification is worth paying for when you run account-based plays, when your buying committee is large enough that any one identified person is unlikely to be the decision maker anyway, or when you sell into Europe where person-level coverage is poor regardless of vendor.
There is a third answer that most vendors will not give you: for many sites, neither is worth paying for, because traffic volume is too low for a percentage-based match rate to produce a workable number of accounts. If you get 800 visits a month and a tool identifies 20%, you are buying 160 company names, most of which are not in your ICP.
The match rate problem
Match rate is the single most important number in this category and the least standardised.
Vendors calculate it differently. Some quote match rate against total sessions. Some quote against unique visitors. Some quote against visitors that were already resolvable, which is circular. Some quote a combined figure achieved only in partnership with another data provider.
When you evaluate, insist on three things. Ask for match rate as a percentage of unique monthly visitors, not sessions. Ask what percentage of matches fall inside your defined ICP, because an 80% match rate that returns mostly students and competitors is worthless. And run the trial on your own live traffic rather than accepting a benchmark from someone else's site, because match rate varies enormously by traffic source, industry, and geography.
We have not run a first-party benchmark across these seven tools on a common traffic set. The figures above are vendor-reported or drawn from third-party reviews, and are cited as such.
Compliance: GDPR, CCPA, and what changes by region
Company-level identification is generally straightforward under GDPR because a company is not a natural person. Resolving an IP address to a business name does not, in most readings, process personal data.
Person-level identification is a different matter. Returning a named individual's LinkedIn profile and work email based on an unauthenticated page view involves processing personal data, and the lawful basis is not obvious. This is precisely why the person-level vendors are US-centric, and why the European vendors in this list stay at company level and market their compliance posture heavily.
If you sell into the EU or UK, take your own legal advice rather than relying on a vendor's compliance page. Several teams we work with run person-level identification for US traffic and company-level for European traffic, geo-splitting the pixel. That is more work to configure and considerably easier to defend.
Which tool fits which team
| Situation | Strongest fit | Why |
|---|---|---|
| US traffic, small budget, want names | RB2B | $149/mo, unlimited seats, no annual lock-in |
| European traffic, GDPR-sensitive | Leadfeeder | Company-level, free tier, EU-native |
| Paid media is the primary channel | Vector | Native ad audience sync is the differentiator |
| Want ID, chat, and outbound in one | Warmly | Consolidation, but verify post-acquisition terms |
| Intent segmentation for European ABM | Albacross | AI segmentation on top of identification |
| Validating the category cheaply | Leadfeeder free or Snitcher | Lowest cost to a real answer |
| Already on Apollo | Apollo.io | No new vendor, adequate depth |

FAQ: Website Visitor Identification Tools
What is the best free website visitor identification tool?
Leadfeeder offers the most useful free tier, covering up to 100 identified companies per month with unlimited users and seven-day data retention. RB2B's free plan gives 150 monthly resolutions but restricts you to company-level identification with no email addresses. Both are enough to establish whether your traffic volume justifies a paid plan.
How accurate is website visitor identification?
Published match rates range from 15% to 80%, but the figures are not directly comparable because vendors calculate them against different denominators. Vector publishes 15 to 30% and Warmly is reported at 15 to 25%, which is probably closer to realistic for person-level resolution. Company-level identification generally performs better because IP-to-company mapping is a more tractable problem.
Is website visitor identification GDPR compliant?
Company-level identification is generally defensible because a company is not a natural person. Person-level identification of EU visitors is much harder to justify and is the main reason person-level vendors concentrate on US traffic. Take your own legal advice rather than relying on vendor marketing.
Can I identify visitors without a cookie banner?
Company-level IP resolution typically does not require consent under most readings, because it does not process personal data. Person-level identification generally does. This distinction is the practical dividing line between what you can run globally and what you should restrict to US traffic.
How much traffic do I need for visitor identification to be worth it?
As a rough guide, below roughly 2,000 unique monthly visitors the identified volume after ICP filtering is usually too small to justify the subscription and the rep time. Run a free tier for a month and count how many identified accounts actually match your ICP before committing.
Does visitor identification replace intent data?
No. Visitor identification tells you who came to your site. Intent data tells you who is researching your category anywhere on the web, including on competitor properties. They answer different questions, and mature ABM programmes run both.
