I Run Marketing Like a Portfolio, and It Changed How I See the Whole Job
I’ll admit something that sounds like a line but isn’t: I manage marketing budgets the same way I manage my own money. Not as a metaphor I trot out on a call — as the actual operating system in my head.
When I look at my own portfolio, I’m not searching for the single best stock to dump everything into. I’m asking a quieter set of questions. How much conviction has each position earned? What does it cost me to hold it? Have I let one winner get so big that a bad week for it becomes a bad year for me? And, the hardest one, have I fallen in love with the thing that’s been working lately — because that’s almost always the one setting me up to get hurt.
Marketing budgets behave identically, and once you see it you can’t unsee it. Every channel is a position. Search, Meta, email, the affiliate deal, that creator partnership you’re still not sure about — each one carries a cost, a risk, and a level of conviction it has genuinely earned or not. The job was never to crown a favourite and shovel everything into it. It’s to allocate deliberately, watch the blended return across the whole book, add to what’s earning its keep, and trim what’s bleeding you while everyone else is mesmerized by the line that’s spiking this month.
Most marketers were never taught to think this way, so a few predictable things happen. They over-concentrate, because concentration feels like focus right up until it feels like a cliff. They worship whatever the last-click report flatters, because attribution is hard and a clean story is comforting. And they treat a rising cost-per-customer as an emergency instead of information — when usually it’s just a position telling you it’s getting crowded.
Take that last one. When your cost to acquire starts creeping and you’re heavy on two or three channels, the instinct is to argue about budget — spend more and power through, or pull back and panic. But the real issue is often saturation: you’re showing the same people the same things until they’re quietly tired of you. You can’t outspend that. You can only out-spread it — take what’s working, make variations, and go find fresh attention where those same people spend the rest of their day. Say a blended cost of forty dollars drifting up toward fifty-five; broadening the mix can settle it back down not by spending less, but by no longer crowding one corner of the room. Diversification gets sold as a defensive seatbelt. In acquisition it’s frequently your second engine.
The discipline that’s hardest for people — and the one I had to learn the expensive way with my own money — is trimming something that’s still going up. It feels insane. It’s working, why touch it? But sizing was never about loyalty to your best performer. It’s about never letting one bet get large enough to really hurt you when it turns, and everything turns eventually. The channel carrying 70% of your growth isn’t a triumph; it’s a concentration risk wearing a party hat.
None of this requires being a better “marketer” in the usual sense. It requires being a calmer investor. The temperament that keeps a portfolio healthy — conviction without infatuation, patience, the nerve to rebalance, the humility to diversify before you’re forced to — is the same temperament that keeps a growth engine healthy.
So when people ask what I actually do, the truest answer is that I stop treating marketing like a calendar of things to post and start treating it like capital to allocate. One of those mindsets produces a lot of activity. The other produces something that compounds. I know which one I’d want to own.
