Also, as a quant marketer I can tell you: exit intent works. Most traffic bounces and never returns. Being able to capture email and nurture leads is a profitable way of maximizing the return of your traffic.
There’s a reason why every furniture store is going out of business and has someone twirling signs: we are evolved to pick out movement and change. An exit intent that inverts the color scheme is obnoxious but only because you have to see it.
The interesting question (for me) is how obnoxious do you go before you start to hurt returns.
This comment is (oddly) unlikely to be popular on HN (odd because of HN’s heritage as an offshoot of YC), but exit intent works. It’s one of the first things I put in place at any new company.
