Compounding Success
What ecommerce marketers can learn from long-term investors.
There is an old investment maxim that says successful investing is often less about knowing what to do than having the discipline to leave well enough alone.
That doesn’t mean literally doing nothing. Good investors establish a strategy, choose their investments carefully, monitor them and periodically reassess them. What they try not to do is react to every movement in the market.
That’s easier said than done — in investing or in marketing.
Ecommerce gives us an extraordinary number of things we can change. New channels, new apps, new offers, new audiences and an apparently endless stream of optimisation opportunities. When results aren’t immediately obvious, it’s very tempting to try something else.
Try a new acquisition channel.
Run it for a few weeks.
Results aren’t spectacular. Stop it.
Install another app.
Launch another offer.
Try an A/B test.
Variant B wins by 6% after 200 recipients. Declare victory.
Change the flow.
Change the offer again.
Hire another agency.
Try AI.
Blast the database.
Repeat.
There is always something new to try and another lever to pull. The result can be an extraordinary amount of time spent changing marketing without ever giving ourselves enough time to understand whether any of it actually worked.
Perhaps there are some useful lessons ecommerce marketers can borrow from long-term investors.
Marketing is an investment
This comparison is more than a metaphor. Many of the behaviours associated with sensible long-term investing have surprisingly direct equivalents in marketing.
| Investing | Ecommerce marketing |
|---|---|
| Investment thesis | Have a clear customer and lifecycle strategy |
| Time in the market | Give a strategy enough time to produce meaningful evidence |
| Compound returns | Allow incremental improvements to accumulate |
| Diversification | Build across multiple lifecycle opportunities rather than searching for one silver bullet |
| Rebalancing | Review and optimise periodically when the evidence warrants it |
| Overtrading / panic selling | Don’t constantly change tactics or abandon a sound strategy because of short-term results |
Of course, the analogy isn’t perfect. Buying shares and marketing to customers are very different activities. But the underlying discipline is remarkably similar: decide where to invest, understand why you’re investing there, measure the return and resist the temptation to change course simply because something else suddenly looks more exciting.
Be selective about where you invest
Smart investors don’t buy every stock simply because it’s available. They think carefully about where they invest their money.
Smart merchants shouldn’t try to market to everybody simply because they can. They should think carefully about who they market to.
Yet much of digital marketing has historically rewarded the opposite behaviour: grow the database, increase traffic, add more channels, send more emails, reach more people.
The underlying assumption is that more must be better.
But a database of 100,000 people isn’t necessarily twice as valuable as one containing 50,000. A customer who purchases once at a discount isn’t necessarily as valuable as one who returns repeatedly at full margin. An email address you acquired years ago isn’t necessarily worth continuing to pay to contact. And someone who happens to be technically contactable isn’t necessarily someone you should contact.
An investor has limited capital and has to decide where to allocate it. A merchant also has limited capital — along with limited time, attention and marketing resources.
The useful question therefore isn’t simply “How many people can we reach?”
It’s “Which customers are worth investing in?”
That distinction matters because good marketing shouldn’t simply produce more customers. It should help produce better, more profitable customers.
Give good investments time
Once an investor has decided where to invest, another discipline becomes important: patience.
Markets fluctuate. Individual investments have good months and bad months. Sensible long-term investors don’t normally abandon an investment every time its price falls, any more than they buy another one simply because its price has just risen.
Marketing performance fluctuates too. One campaign performs brilliantly and the next one doesn’t. Conversion rates move around. Revenue rises and falls. An A/B test appears to have a winner before accumulating enough observations to tell us very much at all.
The temptation is to react. This is where the fiddling starts.
Change the subject line. Change the offer. Change the timing. Change the audience. Change the flow. Change the app.
Apart from the effort involved, constant intervention creates another problem: eventually you don’t know what caused what.
If you simultaneously change the audience, creative, offer and timing and revenue subsequently improves, what did you learn? Perhaps one of those changes worked. Perhaps several did. Perhaps none of them did and something completely unrelated caused the improvement.
Some marketing initiatives also simply need time to produce useful evidence. Lifecycle automation needs enough customers to pass through it. Audience governance needs enough campaigns to reveal its effect on engagement and deliverability. Retention requires customers to have had an opportunity to purchase again.
You can’t measure a long-term effect if you never leave anything in place long enough to become long term.
That doesn’t mean stubbornly sticking with something that clearly isn’t working. An investor should reconsider an investment when the original thesis no longer holds. A marketer should do the same.
The distinction is between changing something because the evidence tells you to and changing something because you’re impatient.
Small improvements compound
This may be where the investing comparison becomes most useful.
Compounding doesn’t look particularly spectacular at the beginning. Its power comes from relatively modest gains accumulating over a long period.
Marketing can work the same way.
Imagine improving the proportion of website visitors who identify themselves by a little. Then improving the proportion who confirm their subscription. Then improving the welcome experience. Then recovering a few more abandoned carts. Then converting a few more first-time customers into second-time customers. Then identifying which customers are becoming disengaged and improving the way you communicate with them.
Perhaps none of those changes transforms the business on its own.
Together, however, they start to change the economics of the customer lifecycle.
And the improvements can build upon each other. Better customer data improves segmentation. Better segmentation improves relevance. Greater relevance can improve engagement. Better engagement can improve deliverability. Better deliverability means more of the people you actually want to reach receive your messages.
Each improvement makes the next one a little more valuable.
This is less exciting than discovering a new acquisition channel that supposedly doubles revenue overnight. It is also considerably more plausible.
The ecommerce industry has spent years searching for silver bullets: the new channel, the new platform, the new app, the new growth hack, the new AI tool.
The silver bullet is a myth.
There’s an old Scots expression:
‘Many a mickle makes a muckle’
In other words: ‘Small gains, accumulated over time, can eventually become something substantial.’
It wasn’t coined for ecommerce lifecycle marketing. But it might as well have been.
Don’t confuse patience with doing nothing
None of this is an argument against experimentation. Experimentation is how we learn. New technology can create genuine opportunities. Strategies should evolve. Underperforming channels should be questioned and bad investments should eventually be stopped.
But experimentation works best when it takes place within a strategy rather than instead of one.
Before changing something, it helps to ask a few basic questions. What are we trying to achieve? Why do we think this change will achieve it? How will we measure the result? How much evidence do we need? How long should we reasonably expect that to take? And what result would cause us to change course?
Those questions make it much easier to distinguish between optimisation and fiddling.
Good investors don’t literally do nothing. They establish an investment thesis, allocate capital, monitor performance and occasionally rebalance. Most importantly, they don’t feel compelled to react to every movement.
Good marketers can do much the same:
- Choose carefully where to invest.
- Give sensible strategies enough time to work.
- Measure what happens.
- Make considered improvements.
- Allow those improvements to compound.
There probably isn’t one big thing that will suddenly transform your marketing. There may, however, be dozens of small things that make it progressively better.
Improve how you identify customers. Improve consent. Improve relevance. Improve conversion. Improve retention. Measure what happens, learn from it, and improve again.
None of those changes may look spectacular in isolation.
But give them time, and they compound.
