Every conversion decision your customer makes is shaped by the environment you create around it. Get that environment right and growth follows almost naturally. Get it wrong and no amount of ad spend will save you. In this episode of Keep Optimising, host Chloe Thomas and I go deep on the consumer psychology principles that drive real e-commerce growth, from acquisition all the way through to pricing and retention.
Why Psychology Comes Before Tactics
It’s easy to forget, when you’re sitting behind a screen staring at dashboards, that there are real humans behind those numbers. Those humans carry the same cognitive biases and emotional triggers whether they’re buying a pair of shoes or signing up for a dating app. Once you internalize that, it becomes a complete game-changer compared to blindly chasing metrics and copying competitors.
But before you can understand your customer’s mindset, you need to get your own right. One without the other is an incomplete framework. Founders who lack the willingness to put themselves out there, test things, and accept failure will never act on even the best psychological insights. The growth mindset comes first.
Psyched Personas: Going Deeper Than You Think
Most businesses build customer personas that describe who their customer is. What I’ve found more useful is understanding what their customer is feeling in the exact moment they interact with your brand. Are they in a rush? Distracted? Just been paid? Just had a frustrating experience? I call these Psyched Personas, and they go a level deeper than the traditional approach.
When I launched a live-streaming app in the US targeting influencers aged 18 to 25, I was the furthest thing from that audience. So I did user interviews, streamed myself for hours, and genuinely walked in their shoes. There’s no shortcut to that kind of understanding, and once you have it, it informs everything: your pricing, your branding, your product decisions, your copy.
Fix the Leaky Bucket First
Before you invest in acquisition, look at your funnel for leaks. The biggest hole is almost always near the beginning of the user journey. Fix that first. Then study your VIP customers, the ones who converted and stuck around, and figure out what made them different. Once you know that, you can replicate it at the top of the funnel with far more precision than any broad targeting strategy.
Acquisition: Stand Out Rather Than Blend In
The temptation when you see a competitor running ads that seem to be working is to copy them. Resist that. Instead, use the Contrast Effect: understand why their ads convert, then find the angle that speaks specifically to your target customer in a way that nobody else is speaking to them. Differentiation is the whole game.
Another powerful tool is the Liking persuasion tactic. Think about Duolingo’s owl, Duo. That character creates a real relationship with users. It makes them feel guilty when they miss a streak, motivated when they hit one. It becomes an anchor in their minds. A mascot or a consistent brand voice can do the same work, quietly and compoundingly, over time.
Pricing Is Context, Not Just Numbers
Pricing decisions are never made in a vacuum. Use price anchors: a high anchor, a low anchor, and a compromise option in the middle that suddenly feels like the obvious choice. And think about timing. Has your customer just been paid? Are they in a moment of frustration or a moment of excitement? The same price point will convert very differently depending on the emotional context around it.
Don’t just slap a discount on something and call it a promotion. Understand what price point genuinely feels like a great deal based on your competitive landscape and your customer’s state of mind. If you’re not testing your pricing regularly, you are leaving money on the table.
The Fresh Start Effect
People are dramatically more open to taking action at certain moments: Mondays, the start of a new month, January, their birthday, a new season. These are temporal landmarks, moments when the mind naturally resets and becomes more receptive to change. Spotify figured this out with Wrapped and Discovery Weekly. Put new products, new offers, or new messaging in front of people at these moments and your conversion rates will reflect it.
Decision Engineering and Magic Moments
Decision engineering is the practice of designing the environment around a choice to steer your customer toward a better outcome, for them and for you. Framing effects, smart defaults, and the way options are presented all change the decision without changing the product itself.
Magic Moments are the points in the customer journey where their emotional state creates a particular opportunity. A moment of hope, a moment of frustration after a price increase, the instant after a successful purchase. These are the windows where the right message, the right offer, or the right experience creates outsized loyalty.
AI Without Psychology Is a Race to the Bottom
As AI makes it easier to produce more content, more ads, and more noise, the brands that understand their customers at a psychological level will be the ones that stand out. Without that foundation, AI just accelerates the race to the bottom. With it, AI becomes a multiplier on something that already works.
