Which Marketing Channel Should You Invest In? Wrong Question.

Written by: Jessica Grace

One of the first conversations I have with almost every new client sounds remarkably similar.

"We've been thinking about investing more heavily in LinkedIn."
"We really need to improve our SEO."
"We've been talking about starting a newsletter."
"We should probably sponsor more events."

Sometimes it's podcasts. Sometimes it's paid advertising. Sometimes it's YouTube. The specific channel changes. The pattern almost never does.

The assumption underneath those conversations is that marketing success comes from choosing the right channels. Find the one you're underinvesting in, and everything else falls into place.

After seventeen years leading marketing organizations, I don't think that's where the decision begins. I think it's one of the last decisions an organization should make.

Most companies choose marketing channels the way they choose lunch. Whatever feels familiar, whatever has the lowest barrier to entry, whatever someone on the leadership team personally enjoys. A founder who likes writing starts a newsletter. Someone comfortable speaking launches a podcast. A visually creative team gravitates toward Instagram. Another company sees a competitor succeeding on LinkedIn and assumes they should be there too.

None of these decisions are strategic.

The channels become the strategy because no one has stopped to ask what role those channels are actually supposed to play inside the larger business.

By the time I'm hired, most organizations already have a collection of marketing activities in motion: social media, conferences, occasional emails, website tweaks, SEO experiments, a PR agency on retainer. The work is happening, but it feels disconnected. Every channel has its own personality, its own cadence, its own definition of success. The brand fragments because every tactic is making decisions independently.

This is one of the reasons so many founders feel like marketing never quite comes together. They're trying to orchestrate a system they never consciously designed. I don't begin by changing the tactics. I begin by understanding the system.

The first phase of every engagement is a comprehensive brand audit. Before recommending a single marketing activity, I want to understand how the organization actually functions: positioning, messaging, customer experience, internal alignment, existing content, analytics, the customer journey, and the way marketing decisions have historically been made. The goal isn't to find what's broken. It's to understand why the current system behaves the way it does.

From there, I build a competitive intelligence engine: how competitors position themselves, what narratives dominate the category, where the opportunities sit, and what the market has already learned to ignore. At the same time, we develop detailed customer profiles and clarify positioning until we share an exact understanding of who the organization serves, why those people care, and what beliefs need to change before they become customers.

Only after that work is complete do we start talking seriously about channels.

People are often surprised by this. They assume the audit, the research, the positioning, and the customer work are separate from channel strategy. They think all the brand work will inform the tactics on each channel, but not actually underpin which channels we choose to activate and invest in. In reality, that work answers almost every important question about channels before we've asked it. Once we understand the business, selecting channels becomes obvious.

If the organization needs to build credibility in a skeptical market, some channels naturally become more valuable than others. If awareness isn't the bottleneck but trust is, that points in a different direction. If the problem is retention rather than acquisition, an entirely different set of investments starts to make sense. Instead of forcing every channel to solve every problem, we assign each one the work it's naturally suited to perform.

I eventually gave this process a name: Channel Purpose Mapping.

The premise is simple, though its implications run deep. Every marketing channel has a primary purpose within the overall marketing system. Not an exclusive purpose, since most channels are capable of accomplishing many things, but a job it performs exceptionally well. Strategy gets simpler when we build around those strengths instead of fighting them.

Most marketing plans never make this distinction. They implicitly expect every channel to support the entire customer journey. We ask Instagram to build awareness, educate prospects, generate leads, create trust, drive conversions, and retain customers. We expect email to introduce strangers to our business while simultaneously nurturing existing relationships. We judge PR by short-term revenue and SEO by its ability to create demand that didn't exist yesterday.

When every channel is responsible for everything, every channel eventually looks like it's underperforming.

Instagram is remarkably effective at creating familiarity. It lets people encounter your organization repeatedly until your brand starts to occupy space in their memory. That repeated exposure matters: it makes every future interaction more productive, because recognition reduces uncertainty. What Instagram generally doesn't do well is close complex B2B consulting engagements. We shouldn't evaluate it as though it does.

Email has almost the opposite profile. It's one of the strongest relationship-building tools available, because it reaches people who have already given you permission to continue the conversation. It deepens trust, answers questions, and maintains momentum over time. What it rarely does well is introduce complete strangers to your organization. That isn't a weakness. It's simply not the role email evolved to play.

The same pattern shows up almost everywhere. SEO captures existing intent. Public relations borrows credibility from trusted third parties. Events accelerate relationships through shared experience. Case studies reduce perceived risk. Referrals compress the trust-building process because belief has already been transferred by someone the customer knows.

None of these channels are interchangeable. They're complementary. That's where systems thinking enters the picture.

Most marketers optimize inside individual channels: improving click-through rates, testing headlines, increasing open rates, refining creative, trying new calls to action. That work is worthwhile, but it only improves the performance of individual components.

Executive marketing leaders spend just as much time optimizing what happens between channels.

A LinkedIn post succeeds because it moves someone to subscribe to the newsletter. The newsletter succeeds because it builds enough trust for someone to schedule a conversation. The consultation succeeds because it reduces uncertainty and creates the confidence to move forward. Each channel hands momentum to the next. No single channel carries the entire customer journey, because that was never its job.

I first recognized this pattern while leading marketing for Treehouse, one of California's first legal adult-use cannabis retailers.

California law placed strict limits on how cannabis businesses could communicate publicly. We couldn't advertise products the way traditional retailers could, and we couldn't borrow a marketing playbook from another industry because one didn't exist yet. At first, those restrictions looked like a serious disadvantage.

Looking back, they were one of the best strategic constraints I've ever worked inside.

The regulations forced us to separate public marketing from private marketing. Our public channels couldn't exist to sell products directly, so they had to accomplish something else. We invested in community events, educational programming, channel partnerships, local artists, wellness workshops, and building relationships. None of it was expected to generate immediate purchases. Its purpose was to build familiarity, trust, and goodwill long before anyone considered becoming a customer.

Once someone walked through our doors or joined our email list, a different marketing system took over. Product education, one-on-one conversations, in store experience, email communication, and staff expertise became responsible for helping people understand what they were buying and why. We stopped asking every channel to perform every job. Each one had a clearly defined purpose, and together they formed a coherent system. Over twenty-seven months, that system helped nearly triple revenue, lift average spend per visit by 50 percent, and quadruple customer lifetime value, while raising more than $10,000 a year for local nonprofits.

I've realized since then that almost every organization faces the same challenge, even without legal restrictions forcing the issue. Most founders think marketing gets complicated because there are too many channels to choose from. I don't think that's true.

Marketing gets complicated because organizations assign the same job to every channel. They duplicate effort, create conflicting KPIs, argue endlessly about tactics, and abandon perfectly good investments because they're measuring them against outcomes those channels were never built to produce.

Once every channel has a clearly defined purpose, something unexpected happens. The strategy gets quieter.

The roadmap starts to organize itself, because every investment has a reason for existing. Measurement gets easier, because each KPI reflects the purpose of the channel rather than the entire customer journey. Teams stop debating whether they should be on the newest platform and start asking a more useful question.

If we added this channel to our marketing system tomorrow, what unique job would it perform that isn't already being done somewhere else?

That's a fundamentally different question from "Should we be on TikTok?" or "Should we invest more in LinkedIn?"

One is about tactics. The other is about system design. That's where the real strategic work begins.
