Field Notes

Follow the data, and the same dollar gets spent differently.

Russ Cersosimo

Near the end of a recent strategy call, a client of mine, a medical professional, told me something every consultant hears sooner or later. Her team was already doing a lot of things: daily content, social posting, a newsletter. She didn't want to pay me to do them too. She wanted me focused on the gaps.

There's a tempting response to that. If all of that is already happening, why isn't it working? Why am I on this call?

I didn't say it. It would have started an argument, and an argument wasn't going to produce a single new client. Instead I said: let's look at the data. No more guessing. The data doesn't lie.

Then I asked one question. Where are your new clients actually coming from right now?

The answer was simple. Referrals from other doctors, and speaking. Her best clients were sent by physicians and health practitioners whose patients needed a piece of care they didn't offer themselves, or didn't have the depth to handle in complex cases. When she presents, people become clients. A recent TED Talk she gave brought in new patients.

The reflex, and what the data said instead

I've spent a long time in marketing, and I know the reflex. When growth stalls, the answer is more. More social. More radio. More ads. More posts on more platforms.

The data pointed somewhere else entirely. Her best clients came because another practitioner they trusted sent them, or because they had seen her speak and believed her. Everything else was activity. Referrals and stages were the result.

That's the real lesson. Once you just follow the data, marketing stops being a spray and becomes something very targeted. The same marketing dollar that would have gone to more volume can be spent in a completely different way, on the one thing that already produces.

So we retargeted the strategy around a single goal: driving referrals from other doctors. Not more social. Not radio. Not ads. Referrals.

Why referrals behave differently

For a specialized practice, a referral from another doctor isn't just a lead. It arrives with trust already attached. The patient's own practitioner has done the persuading before the first appointment is booked. That is buyer psychology working for you instead of against you.

Advertising works best when the offer is simple to compare. A highly individualized service isn't. People need to know who you are and believe you can solve a problem nobody else has solved for them. That belief is built in front of people, not in a feed.

And a doctor only refers to someone they trust and remember. Which raised the next question: what's the fastest way to earn that trust from many peers at once?

The system being built

The answer is the stage. When she's the expert in front of a room of peers, she reaches many practitioners at once, and they see her as a true expert in her niche. Peers who trust her that way remember to refer their patients to her. That is the mechanism the whole system is built on.

It isn't only booking speaking engagements. The approach is an integrated system, and it's being built now:

  • Creating buzz. Steady visibility that gives event organizers and fellow practitioners a reason to know her name before anyone asks.
  • Hosting events, not just waiting for invitations. Events built for health practitioners, where she's the expert on stage alongside nationally recognized names in her field.
  • Building association, fast. Sharing stages with the top experts ties her brand to theirs quickly. People who trust them start to trust her.
  • Mapping who already refers. The practitioners who send her patients today share a profile: they see the value of her work but don't do it themselves. That profile tells us who to invite into the room next.

None of this happens at the flip of a switch. It starts with a clear focus on the niche and the goals, and it will be judged by the same standard that started it: what the data says.

Three moves you can run this week

1. Ask where your last ten clients came from. Don't guess, and don't go by where you spend the most time. Look at the actual source of each one. The pattern is usually obvious once it's written down.

2. Move one dollar. Take one line of spend that the data can't connect to clients and point it at the source that can. Same budget, different target.

3. List the practitioners who already refer you. What do they have in common? What do they believe about your work? That list is the blueprint for finding the next group of referral partners.

The read

Disagreement is information. When a client tells you what they don't want, it's tempting to defend your plan. The better move is to step back from opinions and ask what the evidence shows.

Follow the data, and the marketing gets targeted. Here, that meant putting the same dollar into rooms full of peers instead of feeds full of strangers. The budget doesn't have to get bigger. It has to get pointed at what's already working.

Frequently asked questions

What does it mean to "follow the data" in marketing?

Look at where your recent clients actually came from, one by one, and let that decide where effort and money go. Reach, likes and time spent matter less than the real source of clients.

Can the same marketing budget produce better results?

Often the first step is not spending more but spending differently. Moving money from activity the data can't tie to clients toward the source that produces them makes the same budget far more targeted.

Why focus on referrals from other doctors instead of more social, radio or ads?

When a patient's own practitioner sends them, trust arrives already attached. For a specialized service, that trust is hard to buy with ads, so growing the referral source that already works is usually the faster path.

Why are events the fastest way to earn referrals from peers?

One event puts you in front of many practitioners at once, as the expert on stage. Peers who come to trust you as a true expert in your niche remember to refer their patients to you, and sharing the stage with national experts strengthens that trust.
