The “Slow Bar” Trap: Why Your Progress Bar Might Be Killing Your Sales (And the 200% Profit Hack)
Here’s the uncomfortable truth: right now, someone is adding products to their cart on your site. They’re getting close to checkout. Then they pause. Look at the total. And leave.
Not because your product is wrong. Not because your price is unfair. But because nothing on your site gave them a reason to add just one more item.
You’ve spent months perfecting your product pages. You’ve A/B tested headlines until your eyes bled. You’ve optimised load times, tweaked button colours, and obsessed over every pixel of your checkout flow.
And yet your average order value hasn’t moved.
Meanwhile, brands like Sephora are generating over £2 billion using a single conversion mechanism you’ve probably dismissed as “too simple” or “not relevant to my business.”
