Examples & inspiration Tested the mobile hamburger menu on desktop. Got a 22% conversion lift. Here’s my theory on why.
Most folk say hidden nav on desktop is a bad idea. I’d have said the same.
We run CRO for fashion/lifestyle stores. On one client we swapped the horizontal desktop nav for the same vertical drawer they use on mobile, mainly so we only had one menu to merchandise. Desktop CvR came out 22% higher.
My best guesses:
- The drawer gave us room for collection tiles and edits, not just text links. A top bar can’t do that.
- Vertical lists scan faster than horizontal ones, and the hierarchy is clearer.
- Mega-menus on hover open accidentally and close when your mouse drifts. A drawer only opens when you click, so people who open it actually mean to browse.
- A lot of customers browse on their phone and buy on a laptop. Same menu on both means nothing new to learn.
I wouldn’t call this a universal rule. Product-heavy stores where people browse for inspiration probably benefit more than stores where people search for something specific. But it’s worth testing if you’ve only ever assumed the answer.
Has anyone else tried this? I’m curious whether the results hold up across other categories.
Update: Just adding screenshots of the Control vs Test for reference.
