Your largest measured drop-off

Visits → Starts: lost 1,400 people (2,000 → 600). That's the single biggest gap in the numbers you entered — a sensible place to test the next change.

This flags where visitors are leaving. It doesn't tell you why — that's what user interviews, session replay, and a real change test are for.

Comment cet outil fonctionne

Four inputs, four percentages, one drop-off flag. Nothing more, nothing invented. Copy this into your weekly review and watch the same page's numbers move over time — that's the useful comparison.

Exemple concret

Example: 2,000 visits, 600 starts, 350 completions, 180 opt-ins → 30% start, 58% completion, 51% opt-in, 9% overall. Biggest gap: visits → starts (1,400 people). That says the page itself, not the form, is the current bottleneck.

  • Taux de démarrage = démarrages ÷ visites. Taux de complétion = complétions ÷ démarrages. Taux d'opt-in = opt-ins ÷ complétions. Global = opt-ins ÷ visites. Rien de sorcier — le calcul du coin de table.

À propos des estimations : Percentages are only as good as the inputs. Use the same date range and traffic source for every number, and re-check the raw counts before drawing conclusions.
