Does removing a checkout warning banner lift mobile conversion?
Our mobile checkout opened with a large warning banner and an error-style go back message. We tested removing the banner and softening the message. Conversion moved 0.8% over 9 days, with little difference between versions.

The hypothesis
By removing a large warning banner and softening an error-style go back message, we will cut distraction and confusion at checkout, resulting in more completed orders.
By the time visitors reach checkout, they have already started their order. A large warning banner at the top of the page was no longer needed there and pushed the form down. A separate go back message about vehicle details looked like an error, which could make people worry they had done something wrong.
We tested each fix as its own variation to see which change mattered more.
What we changed
We tested removing a top warning banner and softening a go back message.
The control showed a large warning banner above the checkout form and a go back message about vehicle details. Var A removed the banner. Var B kept the go back option but made the message smaller and calmer, so it no longer read as an error state.
- Large warning banner removed from the top
- Go back option kept
- Message made smaller and calmer
- No longer styled like an error
The result
Conversion moved just 0.8% in 9 days, with no clear winner.
Over 9 days, conversion was 0.8% higher than the control, and neither variation pulled clearly ahead of it. With so little movement between the 3 versions, we called the test not significant and paused it.
What we would do next
Test bigger changes to the checkout flow itself.
Removing the banner and calming the message did not hurt, so both are safe cleanups. But neither moved conversion in a way we could measure, which told us these details were not what held visitors back. Our next checkout tests looked at bigger changes to the flow, starting with a multi-step layout.
