Customers want a personalized experience every time they interact with your company. Whether they’re accessing your website on their laptop or clicking an ad on their mobile device, they expect businesses to know who they are and what they want. Identity resolution, the process that powers identity graphs, makes such personalization possible.

But possible doesn’t mean easy. Multiple touchpoints and devices make it harder to tell whether a user is a new visitor or a long-time customer. Evolving privacy regulations have made this difficult task even more challenging by limiting third-party cookies. Today, marketers need robust identity resolution tools to build complete, accurate customer profiles using first-party data.

What is Identity Resolution?

Identity resolution is the process of recognizing individual users across devices, sessions, and channels by linking all of their behavioral and contextual signals to a persistent profile. It attributes the data from multiple touchpoints to create a unified view of an individual.

This unified view is called an identity graph, a real-time customer profile constructed by matching and merging identifiers like email addresses, device IDs, and session behavior.

Consolidating all of this information into one profile saves time and money, while helping you meet customer expectations effortlessly.

Identity resolution equips you to:

• Maximize conversions with personalized marketing. One-size-fits-all messages often miss the mark. When you know exactly who you’re talking to, you can provide accurate product recommendations and targeted offers each customer will love.
• Engage unknown visitors to turn them into customers. Visitors to your site don’t always sign in or may visit from unfamiliar devices. Avoid creating redundant profiles or missing the conversion by matching these visitors to existing known identities.
• Improve data quality to maximize return on investment for advertising. Don’t spend money showing ads to the wrong audience. Know who your customers are across platforms so you can allocate budget where it matters most.
• Comply with privacy regulations more effectively. Most modern data privacy laws allow users to request data removal. Without an identity graph that links disparate data points to individuals, compliance becomes risky. Resolution helps ensure you know whose data belongs to whom.

Balancing Personalization with Privacy

Privacy concerns are growing, but businesses can still deliver personalized experiences by prioritizing ethically sourced data. Two key types of data that support compliant identity resolution are:

• First-party data, collected directly through interactions such as site visits, form fills, purchases, or support chats.
• Zero-party data, which customers proactively share — like communication preferences, product interests, or survey responses.

While third-party data is declining in value due to regulatory shifts and browser restrictions, responsibly sourced partner data can still enhance identity resolution when privacy standards are met. The key is transparency, consent, and control, building trust while delivering relevance.

How Does Identity Resolution Work?

In considered purchase journeys like buying a vehicle, remodeling a kitchen, or planning a big-ticket vacation, customers don’t convert on their first visit. They browse multiple times, click ads from different devices, read reviews, and often return days or weeks later before reaching out.

Throughout this process, you collect dozens of data points, but they’re often siloed. The advertising team may know someone clicked a Facebook ad. Sales may see a form submission. Meanwhile, your analytics system is tracking anonymous browsing behavior.

Without identity resolution, each of these interactions appears to belong to a different user, giving you a fragmented and incomplete view. The real value lies in recognizing that they all belong to the same person and using that insight to shape personalized messaging and offers.

Identity resolution connects those dots. It collects behavioral and contextual signals across devices and sessions, matches them to a unified profile, and creates a living record of how the customer is engaging over time.

This unified customer view, or identity graph, allows you to:

• Track long research cycles from beginning to end
• Understand which channels are driving conversions
• Personalize offers based on behavioral patterns and preferences
• Spot and re-engage returning customers with tailored follow-up

In categories with long consideration windows and high-value sales, identity resolution is the key to understanding intent and timing and acting on it before your competitors do.
