This article covers storefront best practices for Checkout+, including cart placement, button configuration, attach rate optimization, branding customization, and mobile optimization. These recommendations are based on data from top-performing merchants and are designed to help you maximize your Checkout+ attach rate without hurting checkout conversion.

Please review the best practices below to ensure your storefront delivers a great Checkout+ experience for shoppers.

Important: The first three best practices are requirements for merchants on the Checkout+ rev-share model to ensure healthy attach rates.

Cart placement is the single most impactful decision you can make. The two-button cart experience consistently outperforms checkout-only placements. If Checkout+ is only shown at checkout, you're leaving attach rate on the table.

The example below shows Checkout+ placed directly in the cart using the two-button experience.

One button adds Checkout+ protection; the other declines. Opt-in framing with full price visibility is what drives high attach rates for top-performing merchants.

Important rules for the two-button setup:

• The Checkout+ button must be on top

• It must use your prominent, primary brand color

• Switching the button order or using a secondary color is directly linked to lower attach rates

The example below shows the correct two-button setup, with the Checkout+ button on top in the primary brand color.

Important: Do not swap button order or use secondary/muted colors for the Checkout+ button. Both changes measurably reduce attach rate.

When Checkout+ is live in the cart, no other buttons should compete with the Checkout+ decision. Extra buttons — whether quick-pay options like Shop Pay and Amazon Pay, or navigation buttons like "Continue Shopping" — create confusion at a critical moment in the shopper journey and directly hurt attach rate.

Below are examples of what not to do:

Display a "Recommended" tag on the Checkout+ cart item with a customizable color theme. This reinforces the Checkout+ option as the preferred choice for shoppers.

To enable it, navigate to Admin > Returns Management > Shopper Experience > Checkout+ customizations, or go directly to this page in admin. In the Cart styles section, toggle Recommended tag on and select a color theme to match your brand.

You can add a custom banner image to the info modal header to reinforce your brand at the moment shoppers are evaluating the offer.

These brand customizations are available at Admin > Returns Management > Shopper Experience > Checkout+ customizations, or directly at this admin page.

Use the mobile/desktop preview toggle in the Checkout+ content customizations section in admin to verify the cart experience, modal, and button sizing look right at both screen sizes before going live.

Check for the following on mobile specifically:

• Tap-target sizing on small screens

• Copy length: make sure it doesn't truncate awkwardly

• Confirm the Checkout+ block isn't getting cut off or pushed below the fold

• Use the Desktop/Mobile preview toggle to see how the info modal looks across screen sizes before saving

Displaying button #2 (the decline option) as a text link instead of a full button is available as a customization. This may increase attach rate by making the non-Checkout+ option less visually prominent to button #1, but may reduce clarity for some shoppers.

The example below shows the decline option displayed as a text link instead of a full button.
