If your store uses a custom metafield instead of the default product description, ConvertMate allows you to update the description within that metafield.
Follow these steps to set it up:
Enable the option "Write back product description to a custom metafield."
Enter the metafield name in the format
<namespace>.<key>
. Example:custom.info
.Save your settings. ConvertMate will then fetch your original descriptions from the specified metafield.
After this setup, you can run a new 'On-Page Magic' job, and your custom product description will be included in the updates.
