What Is Data Enrichment?
Data enrichment adds external data to your existing records to make them more useful. Learn how it improves segmentation, personalisation, and scoring.
Key Takeaways
- Data enrichment adds external attributes to your internal records
- Common enrichment: company size, industry, location, technographics for B2B; demographics, interests for B2C
- Enriched data improves segmentation accuracy and personalisation relevance
- Enrichment providers include Clearbit, ZoomInfo, FullContact, and Experian
What data enrichment is
Data enrichment is the process of supplementing your existing customer, prospect, or transaction records with additional attributes sourced from external data providers. If your CRM holds a company name and email address, enrichment might add the company's industry, employee count, annual revenue, technology stack, and the decision-maker's LinkedIn profile. If your eCommerce platform holds a customer's email, enrichment might add their estimated income bracket, interests, and location data.
B2B enrichment
In B2B contexts, data enrichment typically adds firmographic data (company size, industry, location, funding stage) and technographic data (which software tools the company uses — useful for identifying prospects who might switch to your product). Providers like ZoomInfo, Clearbit, and Apollo maintain large databases of company and contact information that can be matched to your existing records via email domain or company name.
B2C enrichment
In B2C contexts, data enrichment typically adds demographic data (estimated age, income, life stage), interest and lifestyle data, and geographic data (property ownership, commute patterns). Providers like Experian, Acxiom, and FullContact maintain consumer databases built from public records, loyalty programme data, and other consented sources. GDPR compliance is critical — ensure your enrichment provider can demonstrate appropriate data sourcing and consent.
Applications
Improved segmentation: enriched data allows you to create more precise audience segments — for example, targeting only companies in the retail sector with more than 50 employees and a specific eCommerce platform. Better lead scoring: a B2B lead from a company that matches your ideal customer profile (enriched firmographic data) scores higher than one that does not. Personalisation: knowing a customer's life stage or interest category enables more relevant product recommendations and marketing content.
Data hygiene and GDPR
Enriched data degrades over time — people change jobs, companies change size, interests evolve. Refresh enrichment on key records quarterly and on your full database at least annually. For personal data enrichment in the UK, ensure your enrichment provider complies with UK GDPR requirements around data sourcing and that your use of enriched data is covered by your privacy policy and lawful basis for processing.
