At its core, B2B identity resolution is the process of stitching together fragmented data to build a single, robust profile of a professional. Enterprise B2B solutions aren’t bought by lone individuals; deals are won through an often multi-month journey involving multiple stakeholders across an organization. To be effective, modern sales and marketing leaders must pivot away from chasing siloed leads and instead focus on strategic, holistic account penetration and engagement across entire buying groups.
This is where identity resolution becomes a significant source of advantage. By connecting IP addresses, LinkedIn profiles, and job functions, you move from a collection of “anonymous data points” to a unified view of the person. Most importantly, these profiles are mapped directly to their parent accounts, finally giving you a clear window into the teams and buying committees you’re actually trying to reach.
Robust professional and account profiles allow marketing and sales teams to move beyond individual leads and effectively engage an account’s full buying committee to deliver relevant omni-channel digital experiences, and measure true account penetration and engagement.
For example, if a prospect from one of your target accounts registers for your webinar, clicks on a LinkedIn post from your company on their home computer, and visits your business website from their office and gets a temporary cookie, it may indicate that this target account may be in-market for your product or service.
Not only do you need to know how this company employee is engaging with your brand or researching similar products and services, and the individual’s role and potential level of influence, you also need to be able to link the behaviors of multiple employees that work for the same company.
The core of B2B identity resolution: the B2B identity graph
A B2B identity graph is the essential enabler of identity resolution. It’s built on several core elements that link disparate data points to form a unified profile of a company, its employees, members of a buying group, or an individual prospect.
Unlike direct-to-consumer (D2C) identity graphs that focus on individual consumers, B2B identity graphs link identifiers to the company a person works for (rather than the household they belong to) and then provides professional and firmographic attributes.
There are four main types of B2B identifiers that–when combined–allow for intelligent identity resolution:
- Firmographic/employer identifiers, such as company name, domain name, and corporate addresses
- Contact identifiers, such as contacts’ work email addresses and job titles (anonymized in Bombora data solutions)
- Offline Identifiers, such as physical addresses and event attendance records
- Digital Identifiers, such as IP address, website cookies, device IDs, and internal user IDs from CRM or marketing automation systems
Anonymous web traffic and identity resolution
One essential element of identity resolution is the ability to deanonymize website visitors. B2B sales, marketing, and advertising teams that include deanonymized website traffic data in their identity resolution process benefit from granular signals that communicate where potential customers work and where they are in the decision-making process.
Website traffic, once deanonymized (meaning the anonymous IP address is mapped to a specific company or persona), provides the deepest behavioral signals. Unlike an email open or an existing CRM record, website activity shows content consumption and intent in real time: which product pages were viewed, which pricing tiers were considered, or which informational documents were downloaded.
This forms the foundation of granular signals used to determine accurately prioritize an account, better understand the buying group, and customize marketing and sales motions.
In B2B, where the focus is at the account level, deanonymizing traffic allows sales and marketing teams to see all activity originating from a target company’s IP address, even from users who have not yet provided their work email address.
Resolving identity at the account level is a view of the entire buying committee’s behavior, signaling that the account is active and primed for engagement.
Applications of identity resolution for B2B sales and marketing
Advanced identity resolution data can be valuable for B2B sales and marketing teams as it solves the problem of fragmented prospect and customer profiles. It links individual interactions—from anonymous website visits and ad clicks to email engagement and CRM records—to a company account profile.
This unification allows marketing teams to build first-party data and use it to inform key account list prioritization, shape digital campaign strategies, personalize content and outreach across owned and paid channels, and be able to more accurately attribute marketing impact and ROI.
Sales teams benefit by receiving high-priority, scored accounts rather than fragmented leads, enabling them to strategically engage an entire buying committee with contextually relevant messaging at the optimal time, and avoid overlooking key buying group members who may ultimately stall a deal.
As an example, one customer used Bombora’s Visitor Insights identity tool to accurately identify when prospects from a target segment visited their website and capture specific interactions with the tailored content they were shown.
The client gained deeper insights into what content to serve, allowing them to strategically optimize the user experience for increased conversion and engagement. In this case, advanced identity resolution data led to a remarkable 75% lift in conversion. Other Bombora clients use the Visitor Insights tool to de-anonymize website traffic and create retargeting audiences in real time to extend prospect engagement.
Bombora’s approach to identity resolution and anonymous website visitor identification
Bombora’s B2B identity graph
Bombora has an extensive B2B identity graph that has been built over more than a decade. Our graph is based on a rigorous multi-step journey that ensures our data is accurate, privacy-aligned, and deployable:
- Collection: We gather digital identifiers from across the B2B ecosystem.
- Unification: Using deterministic and probabilistic methods, we assign unique identifiers to professional profiles, resolving professional and personal devices to a single identity.
- Refinement: We “filter the noise,” removing bot traffic and low-quality data to ensure only meaningful activity remains.
- Enrichment: We add descriptive attributes, including firmographics (company details), demographics (professional role, seniority), and Intent topics (what they are currently researching across our one-of-a-kind Data Cooperative).
- Validation: Every profile undergoes a final quality check to ensure the connections are logical and the data is fresh.
We frequently refresh our identity graph, currently capturing ~3B devices across X domains, to reflect the ever-evolving B2B landscape.
Our identity graph supports digital audiences with higher match rates and global scale than other B2B data providers.
Bombora’s Visitor Insights website visitor identity solution
Bombora’s Visitor Insights goes beyond domain-to-IP matching, using a composite approach that combines robust deterministic data sets with probabilistic methodologies, including a proprietary work-from-home model for holistic identity resolution.
- Deterministic signals use confirmed, direct data points to establish matches.
- Probabilistic models fill in gaps where direct matches aren’t available.
This approach creates a correlation between a site visitor and their respective company, seniority, role, and B2B interests, building out a comprehensive B2B profile.
Bombora also resolves identity through IP address and first-party cookies, hashed business emails from registration forms (HEMs), and single sign-on (SSO) providers.
This is a unique and highly foundational part of a system that connects IP addresses to business domains.
Bombora also employs proprietary behavioral modeling and deterministic traffic signals, and leverages partnerships with reputable, consented vendors (like LiveRamp) to increase accuracy.

Some solutions combine deterministic matching with probabilistic modeling to fill gaps where direct matches aren’t available. Bombora’s Visitor Insights goes further, layering in a proprietary work-from-home model, hashed email matching, and SSO data to resolve visitors to a specific company, role, and level of seniority.
What is a B2B identity graph and how does it work?
A B2B identity graph links disparate identifiers, such as IP addresses, device IDs, company domains, and work emails, into a single, unified profile of a professional and their employer.
Unlike consumer identity graphs, which are built around households, B2B identity graphs connect individuals to their organization and enrich profiles with firmographic and professional attributes like job title, seniority, and department. This gives GTM sales and marketing teams a continuously updated map of who is engaging, which company they represent, and where they sit within a buying committee.
