What does the M2 Product Feed extension make?

The extension allows you to sell products on different shopping engines (Google Merchant Center, Facebook Ads, Shopping.com, Amazon, Bing) exporting product attributes in xml., csv. and .txt files.

The extension can’t work without setting it up correctly. Thus, you can’t persuade Google Merchant or any other shopping engine to accept your misconfigured product feed. Also, you can’t place a static text in the middle of an attribute output (Custom Fields can provide you with the option, however, you’ll need to create it for every new attribute value and place before/after the value).
