Healthcare Marketers Can Now Measure What Local-at-Scale Advertising Actually Drives

For healthcare marketers, local has always been the right instinct. Patients don't choose a provider by scrolling national feeds. They ask neighbors, search by zip code, and make decisions rooted in community trust.

But for years, the challenge hasn't been reaching local audiences. It's been proving that local reach actually drives patient growth.

Today, we're changing that. Nextdoor has partnered with Freshpaint, the HIPAA-compliant, privacy-first customer data platform built specifically for healthcare, to give healthcare advertisers a direct connection between neighborhood-level campaigns and real patient outcomes.

The problem with local healthcare marketing today

Healthcare teams invest heavily in local marketing. But most can't answer a simple question: which neighborhoods actually drive patient demand?

Without a reliable measurement foundation, trust-based engagement gets written off as "brand" spend rather than treated as a performance signal. Local budgets become difficult to justify. And teams default back to other channels, even when growth stalls.

The result: millions of dollars misallocated, and a proven, high-value channel left underutilized.

What Nextdoor brings to healthcare advertisers

Nextdoor reaches 110 million+ verified neighbors — real people at real addresses, making real household decisions.

Unlike broad social platforms that optimize for attention, Nextdoor is built around utility and trust. When a neighbor asks "what’s the best orthopedic clinic nearby?" or "does anyone have a good pediatrician to recommend?" — that's the kind of high-intent moments that directly influence patient choice.

For healthcare organizations with multiple locations, that kind of neighborhood-level signal isn't a nice-to-have. It's the difference between growing the right service lines in the right markets and guessing.

What Freshpaint makes possible

Freshpaint is a HIPAA-compliant customer data platform that enables healthcare marketers to safely collect, unify, and activate first-party data — without exposing sensitive patient information.

Through a server-side Conversion API (CAPI) integration, Freshpaint connects Nextdoor campaign engagement directly to patient actions, inside a controlled, de-identified environment. No risky pixels. No PHI exposure. No compliance blind spots.

Together, here's what the integration unlocks:

• For marketing teams: Incremental reach among verified neighbors, performance visibility beyond Meta and search, and clear ROI tied to specific neighborhoods and service lines — not just clicks.
• For compliance teams: PHI protected by default, server-side data collection, and full governance and auditability.
• For leadership: A unified view of local growth, from first neighborhood exposure to patient acquisition.

How it works

1. Run neighborhood-level campaigns on Nextdoor
2. Freshpaint captures engagement using privacy-safe, first-party data collection
3. Conversion events are defined and measured inside Freshpaint
4. Attribution happens in a controlled, de-identified environment
5. You optimize based on which neighborhoods, messages, and service lines drive real patient outcomes

The result: local trust becomes measurable, accountable growth.

Who this is built for

This integration is designed for multi-location health systems, hospital networks, specialty care groups, and health-adjacent brands that are ready to make local a defensible, measurable growth channel.

Whether your team is exploring CAPI for the first time or looking to deepen an existing setup with neighborhood-level measurement, Freshpaint makes it easy to get started with a proven, HIPAA-safe solution.

Local trust has always driven healthcare growth. Now, with Nextdoor and Freshpaint, it can be measured, optimized, and scaled.
