Imagine you run a furniture company. Your customer, Lauren, recently moved and has been browsing online for new furniture. How can your business ensure these online and offline actions are attributed to the same customer?

The answer lies in a comprehensive identity graph. Without one, Lauren’s online and offline activity may be disparate and not accurately attributed to a holistic customer profile. However, with an identity graph, all of these actions (and any subsequent actions or other identifiers) will be connected to her single customer identity, allowing your company to personalize Lauren’s experiences with your brand and more precisely map her conversion journey.

Most companies struggle to do this on their own. By leveraging an identity graph from an identity services provider, businesses can connect online and offline identifiers, improving outreach and informing future campaigns.

In this guide, we’ll explore identity graphs and their importance by answering the following questions:

We’ll start by defining identity graphs, then enhance your understanding of them and help you integrate them into your marketing strategy.

What Is An Identity Graph?

An identity graph is a foundational data asset that connects and unifies consumer data from multiple touchpoints, devices, and platforms to create a single, consistent, and persistent profile of each individual consumer.

It links disparate identifiers, data points, and signals to a single individual or household, allowing marketers to understand who their customers are across different channels and deliver personalized, targeted marketing.

Identity graphs can include offline and online identifiers, such as:

  • Offline: Names, Postal Addresses, Phone Numbers, Email Addresses
  • Online: Mobile Ad IDs (MAIDs), Unified ID 2.0 (UID2), Hashed Emails, IP Addresses

As the scenario presented illustrates, it’s not only about having the right data but rather piecing data points together to make them actionable. With an identity graph, the furniture company could view all of Lauren’s actions as belonging to her, allowing them to understand what led her to convert and personalize communications. Identity graphs help break down data silos to give your business a single, unified view of its customers that facilitates relevant marketing campaigns.

What Is the Relationship Between Identity Graphs and Identity Resolution?

Identity graphs power identity resolution, which is the process of uniting the disparate identifiers found in a dataset to form unified customer profiles. Businesses use identity resolution for the following purposes:

  • Understand customers to a deeper degree across more attributes.
  • Pinpoint target audiences for marketing campaigns.
  • Customize marketing messages and materials to different audiences.
  • Integrate online and offline data to reach customers across channels.
  • Develop consistent messaging across customer touchpoints.
  • Attribute actions back to individual customers.
  • Manage ad frequency and reduce wasted ad spend.

Deep Sync’s industry-leading identity graph is built from a comprehensive database of over 260 million U.S. consumers and covers 97% of U.S. consumers over 18. It contains three dimensions to resolve identities as precisely as possible:

  • Personal information from our proprietary identity spine
  • Online identifiers linked to known individuals and households in a privacy-compliant manner using Deep Sync IDs
  • Data attributes, including demographic, firmographic, lifestyle, property, and geographic information

What truly makes Deep Sync’s identity graph stand out and facilitate more accurate identity resolution is its roots in offline, deterministic data. Let’s explore what this means and why it’s so important for resolving identities.

What Is the Difference Between Probabilistic and Deterministic Matching?

Probabilistic matching relies on predictive algorithms and heuristics to resolve customer identities. Considering these algorithms produce educated guesses based on the information at hand, they have a wide margin of error and aren’t always accurate.

On the other hand, deterministic matching connects online identifiers based on authenticated data to confidently resolve known profiles to real-world individuals and households. This method uses higher fidelity matching based on observed or shared identifiers to map data points to individual profiles only when there is a determined match, allowing for more accurate identity resolution.

Since Deep Sync’s identity graph is built on offline, deterministic data, it enables accurate, reliable identity resolution and empowers businesses to target and engage customers more efficiently and effectively.

What Are the Benefits of Leveraging An Identity Graph?

When you use an identity graph to resolve customer identities, your business will receive the following benefits:

  • Better customer insights. Uniting customer data points gives you a fuller picture of each individual customer. As a result, you can customize your offerings and messaging, target customers more precisely on the channels they use, and segment them for even deeper personalization.
  • Stronger cross-channel marketing campaigns. The more touchpoints you have with potential customers, the more familiar they’ll become with your brand and, therefore, more likely to make a purchase. Identity graphs power consistent cross-channel marketing so you can serve cohesive, relevant messages across channels that boost conversions.
  • Deeper understanding of the customer journey. Since identity graphs combine online and offline data, you can better understand how customers engage with your business. This information allows you to optimize the customer journey to meet their needs at every stage and predict future customers’ paths to conversion.
  • Enhanced customer experience. Customers who receive more relevant content from your business will have a more positive experience with your brand. Consequently, they’ll be more likely to remain loyal to your company, engage with your business frequently, and recommend your products and/or services to others.
  • Increased efficiency and return on investment (ROI). Identity graphs make it easier to personalize your marketing efforts at scale and reap the benefits. Personalized marketing campaigns can reduce customer acquisition costs by up to 50% and boost revenue by 5-15%, increasing overall ROI by 10-30%.

Incorporating identity graphs into your marketing strategy is a win-win situation. While your customers receive more personalized, relevant messages that speak to their needs on the channels they frequent, your business will have the data it needs to constantly innovate, find new ways to increase sales, and boost ROI.

Why Are Identity Solutions Important Right Now?

Third-Party Cookie Instability

While personalized marketing is always valuable for businesses, identity graphs and identity resolution have never been more critical. Third-party cookies have long been in flux, and their future is increasingly unclear.

Google’s latest update on the issue includes a new opt-in model that many in the industry fear will push privacy-conscious consumers to reject cookies altogether. In fact, experts predict that 70-80% of Chrome users will opt out of cookies.

No matter your stance on Google’s approach, it’s evident that marketers can no longer rely on third-party cookies for targeting and need to invest in more stable strategies for reaching and engaging their target audiences.

Since Deep Sync’s identity graph links online and offline data and updates to align with consumer life changes, it’s a reliable source of truth for audience targeting and engagement that doesn’t depend on third-party cookies. Leveraging an identity graph allows you to future-proof your marketing strategy and remain confident in your ability to reach your audience.

Data Privacy Concerns

Additionally, data privacy is a growing concern among consumers, with 75% claiming they will not purchase from companies they don’t trust with their data. Identity solutions are a privacy-conscious way to understand and engage customers.

Deep Sync’s identity graph uses persistent identifiers to help maintain data integrity while remaining privacy-conscious. We store offline data separately from online data and enable linking this information to pseudonymized individual IDs.

Our approach ensures that you use data in a secure and privacy-compliant manner, allowing brands to better understand and reach their audiences while respecting consumer data protections. In addition, Deep Sync meets, if not exceeds, all applicable consumer privacy requirements, and opt-outs are accepted from every state and are universally applied as “Do Not Sell” requests.

How Should My Business Proceed with Choosing an Identity Graph Solution?

While an identity graph is a powerful tool for better understanding your customers, not every identity graph functions the same. Before deciding on an identity graph solution, answer the following questions:

  1. Are you looking for signal resolution or true identity resolution? While signal resolution links identifiers to a common profile, identity resolution takes this process a step further by connecting identifiers to a known person or household. Ultimately, identity resolution is more complex, allowing for more actionable customer insights.
  2. Which is more important: scale or accuracy? If you want to maximize reach and spread brand awareness, you may opt for scale. Alternatively, if you want to reach a specific audience, a precise, highly accurate model is best.
  3. How much control would you like over the identity resolution process? For teams with more identity expertise, a flexible, modular identity solution will give you more control. However, if you lack expertise—or perhaps lack the resourcing to execute identity resolution on your own—then letting a trusted provider handle your identity resolution needs end-to-end might be a better option for you.
  4. How does your potential provider develop its identity graph? Ideally, your provider will base their identity graph on high-quality, offline data sources. They’ll use a deterministic approach that allows you to be confident in the insights they provide because they resolve back to real people and households.
  5. Is your first-party data clean and ready to be used? Before implementing an identity strategy, ensure your data is clean to maximize its value. Consider working with a provider that offers additional data services—including data hygiene—so you can work through the entire process together.

Clarifying your business’s needs in an identity solution will focus your efforts on finding the right provider and ensure you leverage an identity graph to propel your goals forward.
