Below are the old methods:
Please remove your Facebook Pixel ID from the Shopify Built In Pixel Tracking on your store, otherwise you will get duplicate pixel events and inaccurate data reporting.
Case 1
Please watch our video here to Remove the Shopify Built In Pixel Tracking: https://youtu.be/R3R4etZXoQ4
Here are the Written Steps to Remove Your Pixel ID from the Shopify Built In Pixel Tracking system:
- Login to your Store Admin.
- Click on Online Store.
- Click on Preferences.
- Remove your Pixel ID from Facebook Pixel Field and then click on Save.
- Open Pixel Conversion Pro and Enter you Pixel ID.
Case 2
Also, are you using the App KIT or have you ever used it in the past? It’s not compatible with our app, and it will force the Shopify Facebook Pixel Tracking onto your store, even if you have removed your Facebook Pixel ID from your Preferences page. If you have used KIT in the past you will need to remove any authorizations with Facebook that occurred during the installation process. You may also need to contact Shopify and find out how to remove those authorizations for KIT, because Shopify is the developer for the app KIT.
Case 3
Also, if you have setup the Facebook Marketing component of Shopify inside Shopify it will force the Shopify Built In Pixel Tracking that can cause you to get duplicate pixel events and inaccurate reporting. You will need to disable this also.
Case 4
Also, if you have the Facebook Marketing App by Shopify it will force the Shopify Built In Pixel Tracking that can cause you to get duplicate pixel events and inaccurate reporting. You will need to delete this also.
