E-commerce 2–3%, SaaS trials 5–10%, landing pages vary wildly. Compare against your own baseline trend, not benchmarks.
No segments here — one conversion count over one visitor count per run. Four presets ship with the tool (E-commerce 50/1,000 = 5.00%, SaaS Landing 120/3,000, Email 250/5,000, App Install 800/20,000); save runs to the 10-entry history and compare across runs instead.
Small samples lie: 2/10 vs 3/10 means nothing. Run tests to a few hundred conversions per variant before concluding.
