The Numbers Look Amazing… At First
A typical online shop gets around 1,999 visitors on a normal day. On Black Friday? That shoots up to 4,062. It’s the busiest shopping day of the year by far.
And people actually buy. The conversion rate jumps from 1.92% to 3.4% – that’s a 79% increase. Discounts work, clearly.
But there’s a catch that most retailers probably don’t talk about much.

Then Reality Hits
New analysis of e-commerce data shows what happens after Black Friday ends. Of all the people who buy something for the first time on Black Friday, only 22.59% ever come back within the next 12 months.
The rest – 77.41% – buy once and disappear. They came for the discount, got what they wanted, and that’s it.
So shops spend money on ads, slash their prices, handle the rush, deal with customer service… and then most of those customers are just gone.

Cart Abandonment Barely Changes
You’d think big discounts would solve the abandoned cart problem. They don’t really.
On a normal day, 71.65% of people abandon their carts. On Black Friday, that drops to 70.91%. That’s less than a 1% difference.
People still bail at checkout for the same reasons – complicated forms, unexpected delivery costs, missing payment options, whatever. A 50% off sticker doesn’t fix any of that.
What This Actually Means
Black Friday works as a short-term sales boost. Traffic doubles, conversions spike, and revenue jumps. But as a way to build an actual customer base? The data suggests it’s not great.
Most shops treat Black Friday like the big win of the year. But if you’re losing three-quarters of those customers immediately after, you’re basically renting shoppers, not gaining them.
The challenge isn’t getting people through the door on Black Friday. That part’s easy – just advertise discounts. The hard part is giving them a reason to come back when things cost full price again.
Some shops probably manage this well. But the overall numbers show most don’t. And that’s expensive.
