Hello,
I have Google & YouTube App setup and it’s working without issue sending my product feeds to Google Merchant Center, however, I don’t see how I can map particular fields that are specific to each product category to what’s being sent in the feed.
For ex. if i have a category table, and I want to add the attribute “product_height” which is an attribute associated with the category table in GMC, I don’t see I can map it with the metafield that I created in my Shopify.
Is that option even possible with the Google & YouTube App? or do I have to get an other app that has this mapping setting, or is there something to be done on GMC to map certain field in the feed with certain attributes.
I hope I have clarified my issue/question enough
Thank you in advance
If the option is not available in the manual editing within the google and youtube app. You can add it manually using the editor in Google Merchant Center.
If you have a lot of products, you could map custom metafields with a data feed app such as multifeeds: https://apps.shopify.com/multiple-google-shopping-feeds
And here is a great video showing you all the ways you can edit your products:
Hello Emmanuel,
Thank you for your reply and for the video that you made, it clarifies well how the hierarchy of the overrides works in GMC.
My issue is actually being able to send certain data within the feed, and then I will be able to use it with the help of “rules” in GMC.
I know you mentioned that app that already does that, but if I were to keep using Google & YouTube App, is there a way to specify that certain additional metafields to be sent within the feed?
I noticed that the app creates some additional metafields automatically with the
namespace :“mm-google-shopping” (as shown in the screenshot).
If I create metafields with the same namespace, would they then be sent within the field automatically? and then I can use “rules” in GMC to display them however I want.
Thank you in advance for your help
Okay, I did a test and that actually works automatically without having to set up “rules” in GMC.
For anyone else having this issue of needing to add more fields to their feed using Google & YoutTube App, here is what you do:
go to Settings > Custom data
select products or variants, depending on where you would like the attribute to be attached to.
Add definition :
for the Name: type a name, doesn’t matter what you type except for you (you can use the conventional naming of "Google: Attribute-name")
for the Namespace and key (this is important to have it on exact values):
Namespace: mm-google-shopping
key: attribute_name
so the field will be: mm-google-shopping.attribute_name
Change the attribute_name to the actual GMC attribute name you want to be included in the feed. (Example: “mm-google-shopping.product_height”) ( see screenshot example)
The field will then appear in your product editing page (having it show up on your front end is beyond this thread)
It will be then included in your feed, because is has that specific namespace that we used. and because we had the attribute name as the key, it shows up automatically in GMC for each product that has that value (see screenshots)
Hope this helps.
thats very true. thats how you can set up metaobjects or metafields
I’m glad you found the solution, and shared for others to see what to do! 
This was very helpful for me. I had an issue with Google taking my ‘brand’ as the value in the Vendor field, which was incorrect for the way my products are configured (there was no other way of Google getting my brand). I also noticed one possible option was to set up a Rule which defined ‘brand’ as a static value for all of my products. I’m not sure right now which way will work, as I have to wait for Google to process the changes, but the above helped my understanding. Many thanks!
