Why More Channels Can Hurt Marketing Performance

The problem isn't that you're on too many channels. It's that you can't see which ones are working.

That's the real driver behind channel creep. Not ambition. Not trend-chasing. Uncertainty. When you don't have visibility into what your current channels are doing, adding another one feels like progress. It looks like action. And every platform rep at Google, Meta or TikTok is incentivised to tell you theirs is the missing piece.

So you add it. And the problem doesn't get better. It just gets harder to diagnose.

Nobody starts with twelve channels. They start with two or three, get inconsistent results and start wondering if the mix is wrong. A new platform launches. A competitor appears to be on it. An agency recommends it. So it gets added to the rotation.

The advice to focus on fewer channels is everywhere. Businesses hear it constantly. Then they add one anyway. That's not stupidity. That's what happens when you're flying blind on what's already running. The natural response to uncertainty is more surface area, more experiments, more shots at goal. Without visibility, none of those experiments teach you anything.

A lot of the time, businesses don't even understand how the channels they're currently running actually work. So they just start adding to it and hope for the best. They think putting sprinkles on the cake will fix things. The fundamental issue is they don't understand what drives value and what doesn't, in terms of both labour and investment. If you can resolve that, everything else follows. There's nothing wrong with investing if you're going to make money off it. But if you're not, you're wasting time, energy and money, which is the lifeblood of a company.

There's an incentive problem that nobody talks about enough. Channel specialists exist to sell you their channel. That's not a conspiracy. It's how the industry is structured.

If you're not crushing your own Instagram Reels, what makes you think TikTok is going to be the platform for you? It's common sense. But people do it because they see it as a hygiene piece, something they just have to be on. Meanwhile, everyone from Google to Meta to TikTok is pushing whatever head office told them to push. I've had situations where we were selling an online-only product and I was told we needed to be on radio and television. It didn't make sense.

The specialism thing makes it worse. "I only do search" or "I only do social." I find it so reductionist. They're buttons on a computer that you click. The question isn't whether a channel works in isolation. It's whether it works for your business, with your budget, your team and your ability to measure what it's doing. If the person advising you only sees one piece of the board, they're not giving you strategy. They're giving you a recommendation that matches their job title.

The obvious cost is spend. Money going into something that isn't returning. But the less obvious cost is attention, and that compounds fast.

Every channel you add needs someone to manage it, brief creative for it, pull and interpret the numbers coming out of it. In a lean team, that's not theoretical overhead. That's real capacity being pulled away from the channels that are actually performing. The data gets noisier. The learnings slow down. You're running eight experiments in parallel and you can't isolate a single variable.

It's like chess. You've got pieces on a board and each one can only move in a certain number of directions. Adding more pieces doesn't give you more moves. It gives you more complexity. And if you don't understand how the pieces you already have work, the extra complexity just makes it harder to see the game.

This shows up in Australian businesses consistently. We've scored more than 500 Australian businesses across six dimensions of marketing performance. Data and Tracking is the weakest dimension across the board. The businesses that can't see what's working are the same ones spreading budget across channels they can't measure. That's not a coincidence.

Before adding a channel, and before cutting one, there are three questions worth asking. Does it make volume? Does it make margin? Or does it keep the regulators happy?

If it doesn't do one of those three things, I'm not sure why we're doing it. It might be a staff engagement thing. Fine. But in terms of commercial results and outcomes? No chance.

That test strips the emotion out of channel decisions. It doesn't matter how much coverage a platform is getting or how loudly someone in the business is advocating for it. If a channel can't answer yes to at least one of those three questions with real evidence, it's decorative spend.

Cutting a channel feels risky when you don't have good data. You worry you'll lose something you can't see. And people inside the business push back. I've had it where cutting TV spend was met with "the brand will die." It didn't die. The brand was fine. Revenue from the channels that were actually working went up because they finally got the attention and budget they needed.

I've seen situations where 20% of a marketing budget was sitting across channels returning nothing. Not declining. Nothing. When we cut it and concentrated the spend where the data said it was working, revenue went up 20%. The budget didn't change. The understanding of what was working did.

That's the pattern. Not spending less. Seeing more clearly.

It's the same principle behind why measuring conversion efficiency matters more than chasing traffic volume. The businesses that outperform aren't doing more. They know what's working and they put their weight behind it.

Every channel you add without understanding what your current ones are doing is a bet placed with your eyes closed.

You don't need to cut everything tomorrow. But you need to know what the list looks like. Map what you're currently running against those three questions. Any channel that can't answer yes to at least one of them with evidence is a candidate for review.

It pays to know your numbers. Everything else follows from there.
