How to fix the missing GTIN value error in Google Merchant Center?

You’re welcome!

Apologies, I mentioned Bulk Edit, but I’m actually using Metafields Guru. The free plan comes with 1,000 free credits so you could bulk edit up to 1,000 products. After that it’s an extra $1 per 1,000 credits.

The paid plan gives you more flexibility if you want to do some bulk edits for larger SKU counts, so I guess you could use it to update all your products at once.

The free plan allows you to edit single products right from the product page.

We basically add a new product and once created access the “MORE ACTIONS” dropdown at the top right of the product page, and pick “EDIT METAFIELDS”

It will then open all existing metafields, and we just either add this one if it’s not already listed, or just make sure to switch it to “false”.

I hope this helps.

Wow I am now too experiencing this problem after a year of everything being fine. There has to be a better solution than paying for additional apps or long work arounds. Come on Shopify I pay you to help me sell stuff online and I am hindered in being able to do this because part of the thing I pay you for (an important part) isn’t working !!!

I have left you a replied on your first reply with your details. Based on this I have given you the correct answer: https://community.shopify.com/c/ecommerce-marketing/google-merchant-limited-performance-due-to-missing-identifiers/m-p/1485559/highlight/true#M45365

Hi thank you for your replies. So can I confirm we are using correct GTIN codes on most our products, they are in SKU and Barcode fields within Shopify. Everything has been working fine for a year, just recently boom 47.3% of my products are being suppressed by Google (they have confirmed this). Shopify have confirmed there is an issue too, firstly saying don’t worry about it, but obviously this is an issue. Waiting to hear back from Google Content API because this is a syncing issue. It’s not looking like there will be a resolution any time soon, guess the only option would be a App.

Beana - my understanding is that its not something that Google can solve. Unless you mark custom product = no as suggested in the thread then the Google Barcode field entry doesnt get included in the Shopify feed (as the GTIN that Google require). If its not in the Shopify feed then Google dont have the data and cant do anything. Its for Shopify to fix this.

Hi Neil, yes thank you, I can see when changing the custom product to NO this is working. I am worried though because isn’t the Shopify Product Organization there for a reason and relates to the Google Taxonomy sheet and codes? By removing all mapping how will this impact on Google? I just need an answer to this before bulk editing all my products (4k and more). Plus there might be a better fix in the future, surely? And then I will have to manually go through all my products again and re-map - that would be a pain.

Prior to this bug, Shopify defaulted all values for custom products, since a month and a half the default value is empty. Hence why you now need to manually update this.

Either do it in bulk using a bulk editor app, or do it manually.

This is the only way to resolve the missing barcodes, when they are already added in Shopify.

Hi again, thank you for your time on this. Just to clarify when you say manually update default value you agree that for the moment I need to set all custom types to a NO?

Thank you : ))

Yes - Full guide here: https://feedarmy.com/kb/fixed-shopify-barcodes-gtin-not-showing-in-google-merchant-center/

There is no effect on Taxonomy

Previously when you entered a barcode for a product in shopify then it automatically set the custom product indicator to “no” and the barcode would feed through as a “GTIN” in the Google Feed. Now filling in a barcode leaves the custom product unset and you have to set that to “no” yourself using the guide above.

I farrrrrr prefered the old way

@M0w45 - that ws really useful thanks !!!- actually you can make that easier again by defining that metafield so that you dont have to go into Metafields Guru

Once youve defined that metafield then you can just type “false” on the main product page …

Thank you that’s really useful info : ))

Thanks for the info mate, much appreciated.

Just another example of Shopify’s poor user experience… I come across something like this every freaking day. Rather than focus on marketing I spend hours fixing issues like this!

Sometimes i feel that I should have stayed on big commerce!

I am currently having that same issue. Didi you ever get it resolved?

How long does it take to see the results on Google to know that it worked?

If you correctly apply the rules, in half an hour you can view the updates in Google Merchant Center.

Do you recommend a bulk editor that I can use? I have over 25,000 items to go thru. Also I was told to take the automatic updates off of Google Merchant Center, is that correct?

Using feed rules would be the quickest option.

Disabling automatic updates may introduce a different set of issues.

If you are struggling to setup your data, consider using a different data feed app such as: https://apps.shopify.com/multiple-google-shopping-feeds

Which allows you to also setup rules to display accurate details.

Hi, Neil, I have replicated what you suggest, but when I export the product the csv does not contain false. I wonder if, or somebody else, can help me, as It really looks a good solution.

Depending on the situation false also can be an empty field, when importing and exporting. It depends on how data is read by whatever you are using to read the data. It’s also possible that Shopify exports empty values when it’s false.

However the method you want to remedy this issue, no longer works. But if you want to try, simply add FALSE as the value and upload to Shopify and see the results.

I am continuing to use that method and it does work

The “Google Shopping / Custom Product field” in the standard CSV file is
not used for this purpose and it will be blank.

If you were looking for it in a CSV file you would need to export your
metafields

You can only do this in CSVs using an app like Matrixify which can import /
export Metafields in CSVs
