Summary

Radial came to Healthyish Content with a familiar, but difficult challenge: a strong real-world offering, credible clinicians, and… zero organic search presence. Plus, Radial operates offline clinics in interventional psychiatry—a category where trust is critical, awareness is low, and patients are actively trying to understand treatments they’re potentially unfamiliar with.

That created a unique mandate: Connect high-intent searchers with real-world care to turn online discovery into offline patient demand.

Our goal was multilayered: Build visibility, credibility, and education at the same time—all while competing with large health publishers already capturing early attention.

So we built an authority-first SEO/GEO engine from the ground up, making Radial’s clinicians the stars of the show (aka the core growth lever).

We’ll dig into the details shortly, but here’s a quick peek at what happened in just eight months:

🚀 Domain rating: 7 → 31, a 343% increase

🚀 Organic traffic: 510 → 318,446 search clicks, a 1,556% increase

🚀 Top 3 positions: 1 → 391 search clicks, a 39,000% increase

🚀 Referring domains: 72 → 162, a 125% increase

🚀 Media placements in top publications like Self, Everyday Health, and Prevention

The Challenge

No existing authority or content infrastructure

Radial had a limited library of content, no domain authority to support early rankings, and no internal linking or topical depth. In practical terms, there was nothing helping them show up in search yet—no signals telling Google or ChatGPT “this site is a trusted source.”

As an offline clinic provider, their expertise also wasn’t yet translated into content designed for how people discover information online (or for guiding those searches toward real-world care). Closing that gap meant turning clinical knowledge into a structured, search-visible content ecosystem that could connect online discovery to in-person treatment.

A category that requires education before conversion

Interventional psychiatry treatments like TMS and esketamine (Radial calls this growing category “brain medicine”) are relatively new options for many patients. Most people aren’t arriving with context. They’re starting from zero, asking: What is this? How does it work? Is it safe? Is it right for me?

That creates a different kind of content challenge. Before someone can evaluate providers, they need to understand the category itself. So content has to do more than attract clicks. It has to build understanding and confidence from the ground up. That requires more depth, clarity, and trust than typical top-of-funnel content—all while still being structured to perform in search.

A search landscape where generalists capture attention

Even in an emerging category, there was still meaningful competition for attention. 

Large health publishers were already ranking for relevant topics, often by default thanks to their domain authority. Their content didn’t always go deep, but they still captured early attention—and that’s often enough.

For a newer, more specialized brand, breaking through meant competing on clarity, credibility, and usefulness—not just trying to outrank bigger sites on volume alone. In a landscape where traditional media is no longer the primary gateway to attention, showing up in search is what determines who gets discovered and trusted (more on that in our article about the collapse of mainstream health media).

The Solution

Build a content foundation designed for education, not just rankings

With no existing authority to lean on, the strategy had to earn trust from day one. So instead of starting with keywords, we started with how patients actually think.

We mapped the real questions people ask when they’re trying to understand unfamiliar treatments: 

• What is TMS?

• How does esketamine work?

• Is this safe?

• Is this right for me? 

From there, we developed a library of foundational content at a pace of four to six articles per month, designed to meet patients at that first point of curiosity. Each piece was built to be the best answer available: comprehensive enough to compete with established publishers, but simple enough to understand on a first read.

Structurally, that meant leading with clear answers, breaking down complex concepts in plain language, and guiding readers through the natural next questions they’d have.

At a deeper level, this reflects our core content philosophy: Write the best answer on the internet. To do that, we make clinical content feel human. That means always writing with the reader’s mindset in mind: what they’re worried about, what they’re trying to understand, and what kind of clarity they actually need in that moment.

Turn clinical expertise into scalable authority signals

Radial already had the hard part: credible clinicians with real experience. This includes leadership with deep research and clinical backgrounds. Muir, along with his co-founder Carlene MacMillan, MD, are among the most published authors of scientific research in this field. Muir is also an active voice in the space, regularly publishing and contributing to clinical conversations (including his Frontier Psychiatrists newsletter).

Beyond that, Radial has a deep bench of practicing clinicians, including experts like MaryEllen Eller, MD, Steve Harvey, MD, and Seth Resnick, MD. Their impressive roster brings real-world patient experience across a range of conditions and treatments.

The opportunity, then, was making that expertise show up across everything we published. This taps into a core part of our playbook: Expert insight drives content from the start.

So we made their clinicians the backbone of the content, not just a final stamp of approval. Every article was built with real clinical input—quotes, insights, and review—so their expertise was on full display.

Then we systematized it. Each piece followed the same model: expert perspective, real-world context, clinical validation. Over time, those signals stack.

That consistency is what builds trust at scale. It strengthens E-E-A-T, makes the content feel meaningfully different, and gives both readers and search engines a clear reason to trust what they’re seeing.

Build an authority flywheel with Healthyish Content’s Credibility Engine

Strong content is a start. But to actually compete—especially in a YMYL (Your Money or Your Life) category like mental health—that credibility has to extend beyond your site.

That’s where Healthyish Content’s Credibility Engine comes in. This is a dedicated program we developed to translate clinical expertise into the off-site signals that drive both SEO and LLM visibility (think links, citations, and trusted media mentions). It’s built to partner with PR teams, and Radial was one of the first partners we ran this full playbook with.

The approach combines both proactive and reactive outreach. We identify timely, relevant angles, pitch clinicians as expert sources, and respond to ongoing media opportunities to consistently put Radial’s doctors in the right conversations.

In practice, that meant positioning Radial’s clinicians as go-to voices for journalists covering mental health, depression, and emerging treatments. This transformed their expertise into:

• High-quality backlinks

• Repeated media visibility

• Growing domain authority

From there, it compounds. The Editorial Engine produces content that builds authority on-site. The Credibility Engine amplifies that authority off-site. Backlinks and mentions reinforce rankings and visibility. Each piece strengthens the next, creating a flywheel effect that’s difficult to replicate with content alone.

That compounding grows beyond just amplifying between the engine, and out into the real world. While the engine can start off slowly, credibility picks up steam as mentions and placements lend gravitas to Radial and its clinicians. When a journalist sees clinicians already quoted in credible outlets, they’re more likely to proactively connect to work with that clinician, react positively to outreach, and grow repeated media visibility.

The Results

SEO performance

Radial didn’t see overnight results. Like most brands starting from a low domain authority (DR 7), there was an initial ramp period. For the first 3–4 months, the focus was on building the foundation: publishing core content, layering in expert signals, and earning early backlinks.

Then things started to move.

Around months 4–5, we began to see the first signs of liftoff with early rankings, growing impressions, and initial traction across foundational topics. 

From there, momentum built quickly. Between months 6–8, we saw clear inflection points in both traffic and rankings as the system began to compound.

This is consistent with how we think about the SEO results timeline: It takes time to build authority, but once it starts working, it compounds. 

Within that eight-month window, Radial went from no measurable search presence to ranking for high-intent, non-branded queries tied directly to patient education and treatment discovery.

Just as importantly, that visibility positioned Radial to capture demand from patients actively researching treatment options, bridging the gap between search and in-person care.

By month eight, that translated into major gains across every major SEO metric. Here’s the breakdown:

🚀 Domain rating: 7 → 31, a 343% increase

🚀 Referring domains: 72 → 162, a 125% increase

🚀 DR50+ referring domains: 26 → 60, a 131% increase

🚀 Keyword rankings: 6 → 1,435, a 23,817% increase

🚀 Top 3 positions: 1 → 391 search clicks, a 39,000% increase

🚀 Organic traffic: 510 → 318,446 search clicks, a 1,556% increase

The results are impressive. But how they came together is what really stands out. Foundational content gained traction first, then new content began ranking faster, and finally, the entire system started to scale across more competitive queries.

That progression expanded Radial’s visibility across the full patient journey and turned search into a meaningful driver of real-world patient demand.

Media placements

The Credibility Engine translated directly into real-world visibility.

By consistently positioning Radial’s clinicians as expert sources, we secured placements across a range of high-authority health and lifestyle publications. This translated clinical expertise into real visibility for readers and search engines. We’re talking:

🚀  Media placements in leading publications like Self, Everyday Health, and Prevention 

🚀 Coverage across high-authority domains (DR 65–100), including outlets like Yahoo Health and CNET

Other recent placements include: 

• Yahoo Health

• U.S. News & World Report

• Real Simple (twice)

• Glamour SA

The impact here is twofold. High-authority backlinks increase domain strength, while trusted media placements reinforce Radial’s credibility in a YMYL category. 

Why It Worked

This growth came from a system designed to consistently build and reinforce authority from multiple angles over time. To break it down:

• Growth was driven by authority, not volume: Most SEO strategies rely on existing domain authority to gain traction. Radial didn’t have that advantage, so every piece of content, expert signal, and backlink was designed to build credibility from day one. As that foundation strengthened, performance followed. Content ranked faster, new pages gained traction more quickly, and momentum began to compound.

• Expertise became a growth lever: Many health brands have credible experts, but few use that expertise consistently. At Radial, clinician insight was built into the system, spanning both on-site content and external media placements. That consistency turned individual expertise into a scalable signal that strengthened trust, improved content quality, and reinforced authority over time.

• Authority compounded across channels: Together, the Editorial and Credibility Engines created a system in which each effort reinforced the others, driving compounding growth.

Spotlight: “What Is Ketamine Therapy?” 

Radial’s guide to ketamine therapy is a strong example of how this strategy shows up in practice.

Ketamine is a common entry point into interventional psychiatry. Patients searching for it are often trying to understand whether a treatment is safe, effective, and relevant to them—meaning it’s a high-intent, high-trust query.

We built this piece to meet that moment. It clearly explains how ketamine therapy works, addresses common concerns, and grounds everything in real clinical expertise.

The article includes direct quotes from a Radial clinician along with formal medical review by an additional expert. This combination brings together real-world perspective and clinical validation—essential in a YMYL category.

The results followed quickly:

🚀 Organic traffic: 13 → 1,214 monthly clicks, a 9,200% increase

🚀 Ranking keywords: 13 → 1,000, a 7,600% increase

By showing up for a key early-stage query, Radial becomes part of the discovery process. This builds trust and opens the door to deeper engagement across related treatments.

What This Means For You

Radial didn’t start as a digital-first brand, and that didn’t hold them back. What mattered was translating real-world expertise into content that meets people where they’re already searching. If your business has deep knowledge, there’s an opportunity to turn that into visibility—it just needs to be structured in a way search engines (and real people) can understand.

The bigger unlock is how you use your expertise. Most health brands already have access to credible experts, but that expertise often shows up inconsistently or gets layered on at the end. When it’s built into the system—across content and PR—it becomes a real growth lever, strengthening both trust and performance.

And while authority is often treated as something that takes years to build, this shows it can be accelerated with the right approach. Clear, high-quality content, consistent expert signals, and strategic media placements reinforce each other. Once that system is in place, growth starts to compound.
