CRO without the slop

Conversion rate optimization is the most abused word in growth. Here is what good CRO actually looks like.

Most "CRO" is a junior changing button colors and A/B testing copy that doesn't matter.

Real CRO starts with a funnel. Where are users dropping? Where is intent highest but conversion lowest? What does the data say vs. what does the team feel?

A rigorous CRO program runs 5–10 tests a month, each with a clear hypothesis tied to a specific metric. It uses a stats engine (Evan Miller's calculator, or built-in tools) and doesn't call winners until they hit 95% confidence.

It also tests the right things. Hero copy, pricing structure, social proof placement, signup flow friction — these move the needle. Color contrast on the CTA doesn't.

The mistake most agencies make is running tests that are easy to ship, not tests that move the metric. The mistake most in-house teams make is running too few tests to learn anything.

BAZ runs 60+ tests per quarter per client. Most teams run 4. That's the gap.
