UX team at Trendyol describes using session recording tools like Hotjar to observe seller behavior on the Trendyol Seller Panel without formal user testing. Watching recordings revealed hidden bugs, UI inconsistencies, and a major pain point dubbed the 'Scroll of Death,' where sellers had to scroll back to the top of the page to trigger bulk actions after selecting items. The team iterated through three sticky toolbar designs and tested them with different seller groups, finding a bottom-positioned sticky toolbar triggered by checkbox selection performed best. This led to a panel-wide UI update and is framed as proof of a 'One Hour Theory' for cost-effective UX research.

The Pain Point: The “Scroll of Death”

This is a great example of how session recordings can reveal real user behavior and uncover UX issues that may not be obvious through traditional testing.
I also believe UX research should start by understanding who the users are, what they want to achieve, why they use the product, and what problem we are solving for them.
A simple approach could be:
Understand users → Design → Observe → Adapt → Validate.
Even when direct user observation isn’t possible, having a clear understanding of user goals can help us make better UX decisions from the beginning.
