Why You Keep Seeing Ads for Things You've Already Bought – A Digital Irony

The Curious Case of the Post-Purchase Ad

Have you ever made a purchase—let’s say a new phone case or a fancy kettle—and then, as if on cue, your entire online experience becomes haunted by ads for that exact item? You’re sipping tea, browsing peacefully, and suddenly your browser shouts, “Still thinking about that kettle?” No, thank you. I already own it—and I'm halfway to breaking it.

The Digital Blind Spot in Advertising

Modern advertisers collect vast amounts of data to track your interests, preferences, and spending habits. But for all that data wizardry, there's one thing they often miss: the actual moment you complete the transaction. That’s right—your digital trail screams “interested,” but the system fails to notice you've already clicked Buy Now, received the package, and possibly left a review complaining about the user manual.

A Menu After Dessert

We summed it up with this analogy: Advertisers collect just enough data to know you’re interested in a product – but not quite enough to realise you’ve already bought it. It’s the digital equivalent of someone handing you a menu just as you’re finishing dessert. Imagine licking the last of your tiramisu when the waiter appears asking what you’d like to eat. That’s how it feels scrolling past another ad for something now collecting dust on your shelf.

Why Does This Happen?

It’s mostly down to how tracking algorithms are designed. They recognise browsing behaviour and interpret it as intent, but unless a brand or platform can access your purchase confirmation data, they just assume you're still dithering. This leads to what's called post-purchase retargeting, a fancy term for digital nagging. While it might work in some cases—reminding people to buy socks in bulk—it often ends up being mildly annoying and unintentionally hilarious.
