Why Your Navigation Menu is Killing Your Sales (And the 10:1 “Jam Study” Proof)
It’s just a menu, right? It’s not exactly glamorous. It’s not the first thing a CRO consultant points to. And it’s certainly not what keeps founders up at night.
But here’s the uncomfortable truth: the way your navigation is structured could be quietly throttling your conversion rate – or it could be one of the fastest, lowest-cost levers you haven’t pulled yet.
The problem is, the advice out there is contradictory. Simplify everything. Add more categories. Use a mega-menu. Ditch the mega-menu. Test it. Don’t test it yet.
Most of what gets shared online is opinion dressed up as strategy.
