Consent and first-party data: what does stronger trust mean for ROI?

TL;DR: Stricter privacy rules, fragmented sources and unreliable attribution are pushing marketers toward consented first-party data, according to Usercentrics, which BCG says makes organisations 1.5 to 2.9 times more likely to see better performance than competitors. Stronger data now matters less as a volume problem and more as a governance problem.

Editorial analysis by NHI Mgmt Group, based on content published by Usercentrics: “The ROI of strong data: how to turn trust into growth”.

Key questions

Q: How should marketing teams govern consent across the customer data lifecycle?

A: Treat consent as a governed lifecycle control, not a one-time banner event.

Q: Why does fragmented customer data weaken marketing ROI?

A: Fragmentation breaks lineage, creates duplicates and makes attribution dependent on incomplete signals.

Q: What are the warning signs that a data foundation is too weak for reliable measurement?

A: Common signs include conflicting dashboards, duplicate customer profiles, inconsistent campaign attribution and an overreliance on last-click metrics.

Practitioner guidance

• Implement consent-aware data pipelines Carry consent state with customer records into analytics and activation layers so systems can block unauthorised reuse automatically.
• Reduce dependency on third-party signals Shift reporting and targeting toward first-party sources collected directly through owned channels, CRM, product and service interactions.
• Standardise data quality controls Apply checks for completeness, consistency and deduplication before data reaches dashboards or decision models.

Bottom line: The article’s central lesson is that trust, not volume, is becoming the main driver of usable marketing data.
