What is checkout?
The store's payment process: from cart until payment confirms (or fails). It includes details, shipping, payment method, and error screens.
What is conversion here?
The share of people who, entering checkout (or the funnel you define), complete the purchase. Raising conversion without seeing where they drop is makeup.
Is this anti-Mercado Pago?
No. If "pagamentos rapidos" or a gateway truly removes friction for you, use it. Don't confuse a vendor announcement with a diagnosis of your store.
Is this the same as ownership / retainer?
No; that post is about keys and upkeep after launch; this one is about the payment funnel.
Will a "magic" checkout redesign fix conversion?
Almost never. Without measuring by step / method / device, you change the facade and abandonment just moves. SGD sells diagnosis and concrete changes, not magic.
Should we always remove maps or "powerful" functions?
Not always. Sometimes the UI is strong and the UX isn't: the idea is good and the business isn't ready yet. Measuring friction (and knowing when to roll back) beats paying for the same mistake twice.
Is overall conversion rate enough?
It's a thermometer. The useful map is the breakdown: step, method, device, and gateway errors. That's where cheap changes show up.
