   A CDN stores copies of your images and files in data centers around the world.
2. 2

   Step 2:

   Check that your images are being served from the CDN.

   Image URLs should include "cdn.shopify.com".

   Step 1:

   This is a lower priority fix because Shop Pay is already optimized by Shopify.

   But there are still some things you can check.
2. 2

   Step 2:

   Make sure you're using Shopify's default checkout rather than a customized version.

   The default checkout loads Shop Pay more efficiently.

   Check your checkout settings in Shopify admin.
3. 3

   Step 3:

   If you have dynamic checkout buttons on product pages, test with them turned off.

   Go to a product page and time how fast it loads with and without the buttons.

   Some stores see a half-second improvement.

Step by Step Implementation

1. 1

   Step 1:

   Look for the "Lazy Load" or "Deferred Loading" option and turn it on.

   This tells the reviews widget to wait until customers scroll down to that part of the page.
2. 2

   Step 2:

   Test your product pages in a private browser window to see the improvement.

   Step 1:

   Configure the app to only load on cart and checkout pages.

   Fraud protection isn't needed on your homepage or product pages.

   This removes unnecessary code from most of your store.
2. 2

   Step 2:

   If you have access to theme code, add "async" to the Signifyd script tag.

   This tells the browser to load it in the background.

   Your pages will appear faster while still staying protected.
3. 3

   Step 3:

   Test a purchase flow after making changes.

   Make sure orders still go through and fraud detection still works.

   Check your Signifyd dashboard to confirm transactions are being monitored.
