Hi everyone,
I have listed all of my products and will promote them with google ads. However they don’t get approved by google. It says “you need to add a GTIN or MPN”
I have listed them as “Custom item” so it shouldn’t ask for GTIN or MPN however it keeps asking it.
Do you know why this is happening? Any recommendations?
Thanks in advance
Hey, @ukseller44 !
This is Moira from the Social Care team at Shopify.
Thanks for taking the time to reach out to us here in the Shopify Community. You’ve definitely posted in the right place! I’m more than happy to look into this Google error for you.
Google relies on unique identifiers such as the barcode, MPN, or GTIN to help identify a product and make it easier for customers to find a product when searching. When setting a product to “custom”, Google has to review the product and determine whether they’ve seen the product before, or if it’s a product that they haven’t seen yet. If it’s a product they haven’t seen yet, they will approve of the product without a unique identifier. However, if Google believes it’s a product that they’ve seen before, then they would not approve of it, then you will need to request an exemption from Google.
To request an exemption, you can follow the steps listed in Google’s documentation here:
Another option is to purchase a barcode/MPN and then unmark your products from “custom” and go through the approval process. You can purchase a barcode, MPN, or GTIN here:
For custom products, you can remove the value Brand, MPN, and GTIN, then set the identifier_exists field to false. There should be an option to switch the product to do not have product identifiers under products > more actions > google shopping.
Any product that is marked as False for a custom product must have an internationally recognized barcode added to it. You can check with your supplier/manufacturer for these. If using barcodes, please ensure they meet the minimum requirements found on this page for GTINs or this page for MPNs. This information can be edited using the bulk editor in the channel and this video will show how to access it if needed.
There is also a barcode lookup tool accessible, take a look here:
It appears that other folks have had a similar experience, take a look at this community post, here:
I’d also like to share Google’s Product Categories so that you can find the exact category for your products and add this too using the bulk editor. This will help to improve your Ads performance once you start advertising.
Something to note here is that any products that fall under the Apparel & Accessories categories (clothing, shoes & jewelry would fall under here) will also need to have Size, Color, Age, Condition, and Gender added to each item.
Size (Can be left blank if included in the variants)
Color (Can be left blank if included in the variants)
Age - required
Gender - required
Condition - required
If you have a large catalog and you might also be interested in the Bulk Product Editor & Sync app. This would allow you to mark all products as true or false for custom products at once which will save you some time. It’s free for up to 5 in-app edits per month so it could also help with some other attributes if you have multiple products in the same category for example.
If you have any questions please feel free to thread those below.
Cheers!
@Moira Thanks for the detail explanation.. is there any option that only first variant of the product can be synced with Google merchant center instead of syncing all variant
Hey @Grace_01
As variants are attached to a product that would mean that all variants will sync and align with each product. As a workaround, you could create a brand new product listing that only has the 1 variant you are wanting to sync? Would this work for you?
The most common types of product variations are supported by detailed product attributes for:
color [color]
size, [size]
pattern [pattern]
material [material]
age group [age_group]
gender [gender]
size type [size_type]
size system [size_system]
You might not be able to use these attributes to thoroughly describe your variants if you sell build-to-order custom products or products that vary by other qualities. The best practices below, provide tips for how to submit variants when your products don’t fit the detailed product attributes Google provides.
Best practices for submitting products that vary by unsupported attributes:
Submit a separate product for each variant, making sure that the title, image, description, and price reflect the specific product variant you’re selling.
Be clear in the title [title] attribute about the part of the product that is different between your variants.
Do not provide a value for the item group ID [item_group_id] attribute.
Best practices for submitting custom products:
In your product data, submit either the complete configured product or the components for a product.
If you submit a completely configured product, submit products that are readily available and best-sellers.
If you submit a component of a product, make sure that the image, description, and price reflect the component you’re selling. Learn more about requirements for customized products here.
If your inventory and prices change frequently throughout the day, you might consider using automatic item updates.
The number of variants that Google lets you sync depends on your account type. If you need to increase your product limit, then you can contact Google Merchant Center Help directly.
I do hope this helps! Feel free to let me know if I can clarify anything further.
You could get your own GTIN prefix and register UPCs to your products…This could be a good option if you plan to go omnichannel, trademark/copyright, have a brick and mortar. If you do it, do it correctly (GS1).
@Moira Thanks for quick response.. earlier was using some other Google shopping feed app in that only first variant used to get sync with Google Mecrchant center. It was easier to show best image with first variant in Google ads. But now Shopify Google channel syncs all variants so it’s not possible to show best image for all variants.
Creating a brand new product won’t be possible because there are multiple products.
As going through item_group_id , so is it something we can update the same in Shopify Google channel?
Or is it possible to show or sync only parent SKU by using Shopify Google channel ?
Also how frequently does Shopify Google syncs or updates the feed ?
@Moira After going through feed I can see the item_group_id is already been updated by Shopify Google channel.. so just wanted to know will google show only parent SKU in Ads or it will show each variants ads separately ?
Hey @Grace_01 ,
Great question!
It is my understanding that including the item_group_id in the product feed would ensure that all variant/child products are grouped under the parent product, and variants should never be displayed on their own.
Google also states that there are few conditions in order to show the parent products:
Make sure that your variants use at least one of the variant attributes: color, pattern, material, age_group, gender, size, size_type, size_system, and unit_pricing_measure.
Make sure that the product details displayed on your landing page match the values you provide for each attribute like title, color, pattern, material, price, availability, and image_link.
For further guidance, I have attached Googles help document on Item Group ID:
If you have any questions please feel free to thread those below.
@Moira Is there any way to cross check how ads will appear on google shopping so that we can verify if everything is correct and products are visible in group?
Hey, @Grace_01 !
If you want to see how your ad appears in search results, it’s better to use the Ad Preview and Diagnosis tool rather than to do a search on Google. You’ll see the exact same results as a Google search but it won’t affect your performance stats by accumulating ad impressions every time you search for your ad.
To use the Ad Preview and Diagnosis tool, click the tools icon at the top right of your Google Ads account then click on Ad Preview and Diagnosis under the Planning section. You can also go right to google.com/AdPreview:
If you’re looking to become more confident with investing in Google Ads to grow your business, I recommend checking out this Shopify Compass course where you’ll learn the step-by-step process to launch three different Google Ads campaigns. Shopify Compass provides you with webinars and courses on things like store design, marketing, and more. It’s 100% free for everyone and new content is being added all the time. This program will help you drive more traffic into your store and also convert that traffic into sales.
I do hope this helps!
@Moira thanks for the guide.. after checking Google shows each variants ads separately
Hey @Grace_01
My pleasure, I’m glad to hear you have utilized the Ad Preview Tool! Have you ensured your products have met the conditions in order to show the parent products? Including the item_group_id in the product feed would ensure that all variant/child products are grouped under the parent product, and variants should never be displayed on their own:
Let me know how you get on,
@Moira The product is already have color, size, age group , gender.. and item group id is updated by shopify google channel in feed. So as far as I know the product should display in group.
What type of product are you working with @Grace_01 ? I’d be happy to take a closer look to ensure all conditions have been met. I have attached an example of product data for a T-Shirt below:
Look forward to hearing from you!
@Moira Yes all the details are updated as showing in your screenshot.. product like hand gloves , socks
I found another post on Google forums where a few people are having the exact same problem:
Google decides the format and display of all submitted data. Currently, there is a method to force items to be shown individually, or as a group, or in any other grouping, format, or display.
There are likely many internal and external factors that may help determine how submitted items are formatted and displayed by Google’s automated systems such as submitted data rules, a user’s search behavior, how users search, especially over time, etc. So far, Google has not published any such details.
Parent-products, representative products, sets of product categories, or similar items that are not physically in stock and can be shipped to the user, are not allowed to be submitted, at all.
My suggestion from here is to try reaching out to Google Support as they will be able to directly access your products and provide an explanation as to why the variants are displaying separately. You can find their contact details below:
All the best,
I have created bundles of my products and while the individual products have a UPC, I don’t sell them individually on my website. How can I get google to accept these bundles on their channel? Sometimes it accepts them and sometimes it doesn’t.
Thanks so much!
Hey @CLKNC ,
That’s interesting that sometimes the bundles are accepted and sometimes they are not. Have you come across any notable difference between the products that are accepted?
According to the article linked below, if you are selling a multipack or bundle, use the GTIN of ONE of the products:
Hi,
I encounter the same issue. I am not totally sure I understand but I will try again.
However, I would like to make sure of one thing:
I am an illustrator and I use Print On Demand companies within my Shopify store.
Therefore, is it not these companies that should know/provide the gtin/mpn? How can I know which gtin/mpn to use?
I also chose the option of “custom product” thinking I can skip this process but through your answer I understood that this is not correct.
It would be great if I can learn exactly how to give a gtin/mpn in each product and get approved by google. Without it, it is almost meaningless to have a store.
Looking forward to your reply,
Kind regards,
Vasiliki, rocketsack.com
I get the same message. It is very helpful to know that even after we add all data correctly, there is a waiting period for approval of custom products. Also thanks for the bulk product editor suggestion!
