Why Split Tests Are Like High School

I’m talking about split testing . What is a split test for sex? In fact, many… Let me explain. Everyone says they’re doing it… Just like sex in high school, subtests are all the rage.

Did you measure the results? I mean actual measurements, vs numbers? It’s also a rarity – more often it’s a “measure” like “I think we’re getting more signups”.
