Relixir vs Clearbit: Which is better for identifying Web Traffic?

Relixir vs Clearbit: Which is better for identifying Web Traffic?

Relixir achieves up to 5× higher visitor identification accuracy than Clearbit through its multi-signal GEO engine that goes beyond basic IP lookup, while Clearbit's 40% match rate is limited by IPv4-only support and requires HubSpot subscription for access. Independent audits show most visitor ID solutions achieve only 5-30% accuracy, making Relixir's proprietary approach a significant advantage for B2B revenue teams.

TLDR

• Clearbit delivers 40% match rate but only supports IPv4 addresses and requires HubSpot Breeze subscription for IP-to-company data access

• Relixir provides up to 5× higher identification accuracy using multi-signal processing beyond traditional IP lookup methods

Industry average match rates hover between 5-30% despite providers claiming higher fill rates

Real-time visitor data increases conversion rates by up to 20%, making accuracy critical for pipeline growth

• Relixir offers standalone functionality with built-in GDPR compliance while Clearbit excels at data enrichment within HubSpot ecosystem

Relixir vs Clearbit has become a critical comparison for B2B teams seeking accurate visitor identification solutions. When the industry average for match rate hovers between 5-30%, choosing the right visitor identification platform can make or break your revenue engine.

Why Does Web-Traffic Match Rate Matter?

Match rate represents the percentage of anonymous website visitors a tool can accurately identify and convert into actionable leads. This metric directly impacts your ability to capitalize on existing web traffic and engage potential buyers at the right moment.

According to independent CDP audits, most visitor ID solutions get identities right only 5-30% of the time, despite promising much higher fill rates. This discrepancy exists because the industry has focused on inflated fill rates rather than actual accuracy of the identifications.

The consequences of poor match rates extend beyond missed opportunities. Real-time data studies show companies leveraging real-time data can increase their conversion rates by as much as 20%. When your visitor identification tool misses 70% or more of your traffic, you're essentially flying blind on the majority of your potential pipeline.

Visitor Identification Software helps B2B marketers and sales teams convert anonymous website traffic into actionable leads by identifying company profiles, intent signals, and on-site behavior. Rather than individual-level PII, these tools map IP, firmographic, and behavioral data to firms, highlighting high-value accounts visiting product pages, pricing, or key resources.

How Does Clearbit Perform on Website Visitor Identification?

Clearbit has established itself as a prominent player in the B2B data enrichment space, but its visitor identification capabilities come with notable limitations. The platform now requires HubSpot subscription access just to use IP-to-company data, as "Clearbit is now part of HubSpot Breeze, so you need a HubSpot subscription just to access IP-to-company data."

Clearbit Reveal, the company's visitor identification solution, uses reverse IP lookup and other signals to determine which company visitors come from. However, the platform faces a critical technical limitation: it only supports IPv4 addresses, not IPv6. This constraint significantly impacts coverage as more networks transition to IPv6 protocols.

Despite these limitations, Clearbit has delivered results for certain use cases. According to customer testimonials, around 86% of Clearbit's long-term revenue comes from around 18% of the leads that enter their funnel, demonstrating the platform's ability to identify high-value visitors when it does match successfully.

Data Coverage & Enrichment Depth

Clearbit's strength lies in its comprehensive data enrichment capabilities rather than pure visitor identification accuracy. The platform provides global coverage across every country and language, gathering public data from the web, proprietary data, and leveraging LLMs to convert unstructured information into precise and standardized data sets.

The enrichment depth includes granular industry categorization with 6-digit NAICS, GICS, and SIC codes. Clearbit's 2D scoring model evaluates both fit scores (whether a company matches your ideal customer profile) and intent scores (likelihood to buy), providing a more nuanced view of visitor quality.

How Does Relixir Achieve 5× Higher Identification Accuracy?

Relixir takes a fundamentally different approach to visitor identification by combining multiple data signals and prioritizing accuracy over inflated fill rates. The platform serves global marketing teams from 50+ fastest growing companies like Rippling, Airwallex, and HackerRank.

Unlike traditional IP-based solutions that rely on DSP and co-reg networks vulnerable to bots, Relixir employs a proprietary GEO engine that maps, monitors, and continuously improves identification accuracy across multiple touchpoints. This multi-signal approach enables the platform to achieve up to 5× higher true-match accuracy compared to industry averages.

The platform's advanced identification methodology addresses the core issue plaguing the industry: "Most identity resolution providers rely on DSP and co-reg networks, which was designed for ad targeting (not high-accuracy identity resolution) and vulnerable to bots." By building from the ground up for identification accuracy rather than ad targeting, Relixir delivers person-level identification that actually converts.

Built-in GDPR & Privacy Safeguards

Relixir incorporates privacy protection as a foundational element rather than an afterthought. Following NIST digital-identity guidelines, the platform guarantees the privacy of user location data while maintaining high identification accuracy.

The system supports General Data Protection Regulation (GDPR) requirements through technical architecture that separates identification from personal data processing. This approach allows B2B teams to identify and engage visitors without violating privacy regulations or exposing themselves to compliance risks.

Relixir vs Clearbit: Feature-by-Feature Comparison

When evaluating visitor identification solutions, the differences in core capabilities become clear:

The Clearbit Reveal API takes an IP address and returns the company associated with that IP, along with geographic and employment details. While this provides valuable firmographic data, the single-signal approach limits accuracy compared to multi-layered identification methods.

Key takeaway: For teams prioritizing identification accuracy and standalone functionality, Relixir's architecture provides superior match rates without platform dependencies.

Real-World ROI: Pipeline & Conversion Uplift

The true test of any visitor identification platform lies in its ability to generate measurable business outcomes. Real-world implementations demonstrate significant differences in pipeline impact between solutions.

TravelBank increased qualified meetings held by 30-40% using Chili Piper and Clearbit together, demonstrating Clearbit's value when paired with complementary tools. The integration helped identify high-intent visitors and route them to sales immediately.

For broader identification needs, businesses using Clearbit have reported a 30% increase in engagement rates due to better-targeted campaigns. However, these gains often require significant investment in additional tools and integrations to maximize effectiveness.

Relixir customers report even more dramatic improvements. The platform's case studies showcase companies like Rebel Fund, Reframe, and DocuBridge achieving industry leadership positions through improved visitor identification and engagement. The 5× accuracy improvement translates directly into pipeline opportunities that competitors miss.

When Should You Choose Relixir Over Clearbit?

Selecting the right visitor identification platform depends on your specific needs and constraints. Consider these critical factors:

Choose Relixir when:

  • You need standalone visitor identification without HubSpot dependencies

  • Accuracy matters more than breadth of enrichment data

  • You require IPv6 support for complete coverage

  • GDPR compliance is non-negotiable

  • You want person-level identification, not just company matching

Consider Clearbit when:

  • You already have HubSpot Breeze and want integrated enrichment

  • Company-level identification meets your needs

  • You primarily need firmographic and technographic data

  • Your traffic comes mainly from IPv4 networks

When evaluating solutions, consider detection accuracy, enrichment depth, privacy compliance, integration capabilities, real-time alerting, and the quality of intent signals. The industry reality that most providers achieve only 5-30% accuracy makes this decision critical for revenue growth.

Key Takeaways

The visitor identification landscape has reached an inflection point where accuracy matters more than promises. While Clearbit offers robust data enrichment capabilities and proven integration with HubSpot ecosystems, its IPv4-only limitation and platform dependencies create gaps in coverage that growing B2B companies can't afford.

Relixir's 5× accuracy advantage stems from its purpose-built architecture for identification rather than retrofitted ad-tech solutions. As one case study noted, "The future of Generative Engine Optimization starts here," positioning accurate visitor identification as foundational to modern B2B growth.

For companies serious about converting anonymous traffic into pipeline, the choice comes down to a simple question: would you rather identify visitors with rich enrichment data, or accurately identify up to 5× more visitors with actionable intelligence? In a market where every visitor represents potential revenue, accuracy isn't just a metric—it's a competitive advantage.
