Website Visitor Identification
Overview
Most B2B sites convert 2–3% of traffic to forms — the rest looks like dark traffic. Visitor identification (deanonymization) recovers company or person signals from anonymous sessions. The mistake: buying RB2B or 6sense before deciding identification level, running person-level ID on EU traffic without privacy review, or routing every alert to SDRs without an ICP filter.
This skill is the canonical home for visitor ID strategy: person vs business decision tree, vendor comparison (Clearbit/Breeze, RB2B, 6sense, Demandbase, ZoomInfo WebSights, Leadfeeder/Dealfront, Warmly, Koala, Factors.ai, Albacross), privacy operational checklist (not legal advice), and GTM workflows from website visit → MQL or guardrailed outbound trigger.
Frameworks Referenced
- HubSpot Breeze Intelligence (Clearbit heritage). Company Reveal on visit; form enrichment for person + firmographics in HubSpot-native stacks.
- Dharmesh Shah (HubSpot). Visitor ID instruments the Attract stage of
the inbound flywheel — permission-based follow-up after self-directed research.

to dark social — pair with

When to Use
- "Identify companies visiting our website"
- "Set up Clearbit Reveal / Breeze Intelligence"
- "RB2B vs Warmly vs Koala"
- "Person-level vs company-level visitor ID"
- "Website intent data program"
- "GDPR / CCPA for visitor deanonymization" (operational — not legal counsel)
- "Slack alerts for website visitors"
- "Route visitor intent to sales"
Prerequisites
- ICP defined (
icp-scoring) - CRM with account + contact model
- Consent management for EU traffic (
1p-tagging-pixels) - UTM taxonomy (
campaign-governance) for source attribution
Step-by-Step Process
Phase 1: Choose Identification Level
Load references/person-vs-business-identification.md.
- Map primary motion: ABM account prioritization → company; authenticated PLG → person (1P); SDR outbound trigger → person (guardrailed).
- Run privacy go/no-go (
references/visitor-id-privacy-gtm.md) before person ID. - Document decision: level, lawful basis note (counsel confirms), geo scope.
Phase 2: Vendor Selection
Load references/visitor-id-vendor-comparison.md and
templates/visitor-id-vendor-eval-scorecard.md.
| Need | Directional pick |
|---|---|
| HubSpot stack | Breeze Intelligence / Clearbit Reveal |
| Enterprise ABM | 6sense OR Demandbase (one) |
| SMB company ID | Leadfeeder/Dealfront or Albacross (EU) |
| Person LinkedIn ID | RB2B (US-primary, privacy review) |
| PLG sales-assist | Koala or Warmly |
| Analytics + firm ID | Factors.ai |
Run 30-day pilot: ICP-qualified rate, false positive sample (n=50), cost per
qualified ID. Register vendor in gtm-spend-management → GTM-Data class.
Phase 3: Privacy & Consent (Operational)
Load references/visitor-id-privacy-gtm.md.
Disclaimer: Not legal advice — involve privacy counsel for person-level ID.
- Update privacy policy disclosures
- Fire visitor ID scripts after consent in EU
- Sign vendor DPA (
vendor-contracts) - Wire suppression list to CRM + sequencer
- Document security questionnaire triggers
Cross-links: references/gtm-data-exchange-playbook.md,
references/gtm-security-hygiene-basics.md,
references/security-questionnaire-deal-guide.md
Phase 4: Build Workflows
Load references/visitor-identification-playbook.md.
Company ID → MQL path:
Visit → vendor ID → enrich → ICP filter → intent score → inbound-triage routing
Person ID → outbound trigger (if approved):
Person match → privacy gate → ICP + confidence High → enrich email →
cold-email-strategy trigger branch (≤2 touches) → human on reply
Integrations: CRM account/contact, Slack (templates/visitor-alert-triage-checklist.md),
Clay/n8n webhooks, SEP enrollment rules.
Phase 5: Measurement & Governance
| Metric | Purpose |
|---|---|
| ICP-qualified ID rate | Quality over raw volume |
| Alert → meeting | ROI on person ID |
| False positive rate (sampled) | Vendor renewal input |
| Opt-out / complaint rate | Kill switch for person ID |
Quarterly: stack overlap audit (revops-tech-stack), spend review
(gtm-spend-management).
Output Format
Visitor identification program document:
- Identification level decision + rationale
- Vendor selection with eval scorecard
- Privacy operational checklist status
- Workflow diagrams (company MQL + person trigger)
- Slack channel design + triage SOP
- CRM field map + integration contracts
- Anti-pattern acknowledgments
See templates/output-template.md.
Quality Check
- Person vs business decision documented with decision tree
- ICP filter runs before CRM write or sequence enrollment
- Privacy checklist complete; person ID has counsel review if EU traffic
- Vendor comparison includes identification level column
- Slack triage checklist assigned to owners
- UTM/source attribution wired (
campaign-governance) - Vendor in spend register with owner + renewal
- Anti-patterns addressed: no spam-all, opt-outs honored
Common Pitfalls
Person ID without privacy review. GDPR/CCPA exposure. Fix: company ID default; person ID only after
visitor-id-privacy-gtm.mdgates + counsel.No ICP filter. SDRs chase ISPs, agencies, and universities. Fix: automate
icp-scoringbefore any alert or CRM create.Duplicate intent vendors. Clearbit + 6sense + Leadfeeder + RB2B all firing. Fix: Brinker consolidation — one company + one person max.
Creepy outbound copy. "I saw you on our pricing page" destroys trust. Fix: signal-anchored relevance via
cold-email-strategy— not surveillance tone.Ignoring opt-outs. Visitor ID contact opts out on email but stays in RB2B alerts. Fix: suppression sync across CRM, sequencer, Slack enrollment.
EU scripts before consent. Non-essential tags fire on page load. Fix:
1p-tagging-pixelsconsent-first deployment.
