# Which Shopify app embeds should stay enabled? | Theme Stack Guide

Source: https://themestackguide.com/audit-theme-app-embeds/

Keep an app embed only if you can name the customer-facing job it performs. Disable unused embeds in a theme copy, then test the storefront before publishing.

## Run the smallest useful test

Duplicate the live theme. Change one thing, use the same page and device, and record what happened. If the change breaks a customer path, roll it back before touching production.

## What to verify

Check the home, collection, product, cart, and checkout path on a phone. Confirm the page still works with a slow connection and that the business owner for the feature agrees it can change.

## Bottom line

Keep an app embed only if you can name the customer-facing job it performs. Disable unused embeds in a theme copy, then test the storefront before publishing.

## Frequently asked questions

### What should a personalization field include?

A clear label, a character limit that matches what production can actually handle, and a preview or plain confirmation of the entered text on the product and cart pages. Ambiguity at any of those points creates remakes.

### How do I price product personalization?

Charge for the labor and the risk, not just the materials. Personalized items usually cannot be resold after a return, so the fee should reflect that, and the policy should be stated before checkout, not after.
