The CRO toolkit operators actually use.
13 production-grade CRO calculators — conversion math, test sizing, statistical significance, funnel diagnostics, and revenue impact modeling. Built for operators who ship.
How SAZ runs CRO programs.
The principles every SAZ CRO engagement is built on. Skip these and the math doesn't matter.
Diagnose before you optimize
Most CRO programs ship tests that move noise instead of needles. Start with funnel diagnostics — find the highest-leverage stage before designing the first variant.
Size the test before you run it
Under-powered tests are the #1 reason teams ship losing variants. Use a sample size calculator first — every time.
Confidence ≥ 95% before shipping
Anything below 95% confidence is directional noise. Run longer, increase sample size, or accept the null result.
Compound, don't chase
CRO is a flywheel — a 2% lift per quarter compounds to a 27% annual lift over five years. Resist the urge to chase shiny tests.
The toolkit, end-to-end.
From baseline math to A/B test sizing to funnel diagnostics — the calculators that power real CRO programs.
Five phases, compounding outcomes.
The phased approach SAZ uses on every CRO engagement. Skip a phase and the program stalls.
Analytics foundation
Validate event tracking, funnel definitions, and revenue attribution. No analytics, no CRO.
Funnel diagnostic
Use the funnel drop-off calculator to identify the stage with the highest leverage. Focus there first.
Hypothesis development
Mix quant (session recordings, form analytics) with qual (user interviews) to build hypotheses worth testing.
Test execution
Size every test. Run to significance. Document every learning, win or loss.
Compounding rollout
Ship winners. Roll learnings into the next test backlog. Operate a weekly review cadence.
Want the SAZ team running a CRO program for your business?
Calculators are useful. A senior CRO program is a step-change. SAZ runs structured experimentation programs — analytics foundation, hypothesis backlog, weekly experiment cadence — for operators serious about compounding conversion.
Run a real CRO program with senior partners.
