Why look at the funnel, not just conversion rate?
Overall conversion rate is one number that hides the story: do visitors fail to reach products, view them but not add to cart, or abandon at checkout? Each stage has completely different fixes.
The tool calculates the effect of raising each stage by the same number of percentage points, because improving the weakest stage usually brings the most extra orders for the same effort.
FAQ
Good to know
Where do I get the stage rates?
From the purchase journey reports in Google Analytics 4 if e-commerce events are set up, or from your store platform’s analytics dashboard.
How is overall conversion rate calculated?
By multiplying the stage rates together, or dividing orders by sessions. Example: 60% × 10% × 50% × 60% = 1.8%.
Why does the weakest stage give the biggest gain?
Because one extra point on a small rate is a bigger relative increase. Raising a stage from 10% to 11% lifts orders by 10%; raising one from 60% to 61% lifts them by under 2%.
Should I use sessions or users?
Use the same base for every stage. Sessions are the most common in analytics; what matters is consistency when comparing periods.
