Google 产品数据违规
若要在 Google 上展示您的产品，您需要遵循 Google 的产品数据指南。Google 要求您提供有关产品的准确信息，以便向相应客户（例如搜索了您产品描述中包含的关键词或浏览了您的产品所属的产品类别）显示这些信息。如果您没有提供准确的信息，那么 Google 上的客户可能会通过搜索找到您的产品，但您的产品与他们要搜索的内容并不相关。这意味着客户购买您产品的可能性较小，并可能导致 Google 停止向客户展示您的产品。
如果您的产品缺少产品数据或产品数据无效，它们则不会出现在免费产品页面和 Google 购物广告中，或者显示效果有限，例如展示次数和点击次数较少。
常见的数据质量警告
为确保产品获得批准并展示给 Google 用户，请查看以下解决方案，然后更新相关产品的数据。

步骤：
在您的 Shopify 后台中，转至销售渠道 > Google。

在在 Google 中供应列中，取消选中每个存在错误的产品。
点击保存。
产品标识问题
大多数产品都有产品识别码，例如全球贸易项目代码 (GTIN)、制造商零件编号 (MPN) 或产品厂商（品牌）。Google 会检查您为产品添加的任何识别码。如果产品识别码存在问题，您的产品上可能会显示以下错误之一：
条码错误
缺少 ID（GTIN 或 MPN 和品牌）
值无效 (GTIN)
识别码不正确 (GTIN)
值无效 (MPN)
产品识别码不正确 (GTIN)
无效 [条码]
条码长度不正确
具有产品标识问题的产品会获得有限的显示效果；
缺少 GTIN 的产品不会同步到您的Merchant Center 账户 (MCA)。
GTIN 不正确或缺少 GTIN 的产品不会同步并且不会获批。
缺少 GTIN 和 MPN 的产品会获得有限的显示效果。
请查看以下解决方案，然后更新相关产品的数据：
分配给适用产品的有效唯一产品识别码 (UPI)。UPI 包括 GTIN、MPN 和品牌名称。
GTIN 是商品的唯一数字识别码，通常与零售商品上打印的条码相关联。
如果您的产品没有 GTIN，您可以使用 MPN 和条码值。
GTIN 通常由 8、12、13 或 14 位数字构成。请检查您提交的 GTIN 数字位数是否过多或过少。
定制产品（例如艺术品或手工商品）不需要 GTIN。若要将您的产品指定为定制产品，请查看产品多属性并选择更多操作 > Google 字段 > 产品识别码，然后勾选这是定制产品。
缺少值 [品牌]
存在此错误的产品不会在 Google 上显示。
您需要为所有新产品添加品牌值，电影、书籍和音乐录制品品牌除外。请查看下面的解决方案，然后更新相关产品的数据：
在 Shopify 后台中，在组织下的厂商字段中，向产品详情中添加品牌。
请勿提交诸如无、通用、无品牌或不存在之类的值。
如果您自己制造产品，或者产品属于通用品牌类别，那么您可以提交商店名称作为品牌值。
如果产品没有品牌，请使用制造商或供应商名称。
过度使用大写字母
存在此错误的产品不会在 Google 上显示。
请查看以下解决方案，然后更新相关产品的数据：
删除过度使用的大写字母或花哨的大写字母用法，这可能导致客户不信任您的广告和产品页面。
查看 Google 销售渠道的设置选项卡，确定将向 Merchant Center 账户发送哪些产品标题和描述。
从 Shopify 后台的产品部分中，更新 Google 提取标题的位置（主标题和描述或是位于底部的 SEO 信息）中的标题。
通用图片
存在此错误的产品不会在 Google 上显示。
请查看以下解决方案，然后更新相关产品的数据：
对于每款商品，您需要上传一张能够清晰展示要宣传的产品的主图片。
不允许使用的通用图片示例包括 logo 图片或表示“无可用图片”的文本。
图片上存在促销叠加内容

请查看以下解决方案，然后更新相关产品的数据：
上传不含促销文字（如 logo 或行动号召 (CTA)）且没有水印等阻碍因素的新图片。有关详细信息，请参阅 Google 的帮助文档修复图片上的促销叠加内容和选择接受自动图片改善。
图片过小

图片的文件大小必须小于 16 MB。
请勿放大图片或提交缩略图。我们建议产品占整个图片的 75%–90%。
值无效 [Google 产品类别]
出现此错误的产品会获得有限的显示效果。
请查看以下解决方案，然后更新相关产品的数据：
提供有效的 Google 产品类别 (GPC) 值。
输入尽可能具体的类别。例如，仅输入礼服会导致错误，但输入“服装和配饰”>“服装”>“套装”>“礼服”则会被接受。
存在冲突的值 [GTIN、品牌]
出现此错误的产品会获得有限的显示效果。
请查看以下解决方案，然后更新相关产品的数据：

Google Product Data Violations
To show your products on Google, you need to follow Google’s product data guidelines. Google requires that you provide accurate information about your products so that they can be displayed to the appropriate customers, such as those searching for key terms that are found in your product description or browsing a product category that you product belongs to. If you don't provide accurate information, then customers on Google might find your products through searches that are unrelated to what they are searching for. This means that customers are less likely to purchase your products, and can lead Google to stop showing your products to customers.
If your products have invalid or missing product data, then they don't appear in free listings and Google Shopping ads or they appear with limited performance, such as lower impressions and clicks.
Common data quality warnings
To ensure your products are approved and are shown to people across Google, review these solutions and then update the data for the affected products.
If you have a product warning from Google that isn't listed on this page, then visit the Google Help Center and search for the specific error.
Violation of Shopping ads policy
Product identification issues
Missing value [brand]
Excessive capitalization
Generic image
Promotional overlay on image
Image too small
Invalid value
Conflicting values [GTIN, brand]
Violation of Shopping ads policy
Products with this error aren’t shown on Google.
Review these solutions and then update the data for the affected products:
This error indicates that some or all of your products violate the Shopping ads policies.
If you request a re-review of your products and aren't approved, then remove all violating items from your product data.
Steps:
From your Shopify admin, go to Sales channels > Google.
Under the Product status section, click Manage availability.
In the Available to Google column, uncheck each product with an error.
Click Save.
Product identification issues
Most products have a product identifiers, such as a Global Trade Item Number (GTIN), Manufacture Part Number (MPN), or the product vendor (brand). Any identifiers that are added to your products are checked by Google. If there is an issue with a product identifier, then one of the following errors might display on your product:
Barcode errors
Missing IDs (GTIN or MPN and brand)
Invalid value (GTIN)
Incorrect identifier (GTIN)
Invalid value (MPN)
Incorrect product identifier (GTIN)
Invaild [barcode]
Barcode not correct length
Products that have product identification issues have limited performance;
Products with a missing GTIN won’t be synced to your Merchant Center Account (MCA).
For incorrect or missing GTIN errors, products aren’t synced and are disapproved.
Products that are missing a GTIN and MPN have limited performance.
Review these solutions and then update the data for the affected products:
Valid unique product identifiers (UPI) assigned to applicable products. UPIs include GTINs, MPNs, and brand names.
A GTIN is a unique numerical identifier for commercial products that’s usually associated with a barcode printed on retail merchandise.
If your product doesn't have a GTIN, then you can use an MPN and barcode value.
GTINs are typically 8, 12, 13, or 14 digits. Check if the GTIN you submitted has too many or too few digits.
Custom-made products, such as art or handmade goods, don’t need a GTIN. To designate your product as a custom item, view your product variants and select More actions > Google fields > Product identifier, and then check This is a custom product.
Missing value [brand]
Products with this error aren’t shown on Google.
You need to add a value for all new products except for movies, books, and musical recording brands. Review these solutions and then update the data for the affected products:
In your Shopify admin, add the brand to your product details within the Vendor field under Organization.
Don’t submit values such as N/A, Generic, No brand, or Does not exist.
If you manufacture the product yourself or the product falls into a generic brand category, then you can submit your store name as the value for the brand value.
If the product doesn’t have a brand, then use the manufacturer or supplier name.
Excessive capitalization
Products with this error aren’t shown on Google.
Review these solutions and then update the data for the affected products:
Remove excessive or gimmicky use of capitalization, which can cause customers to perceive your ads and listings as untrustworthy.
Check the Settings tab of the Google sales channel to determine which product title and description is sent to the Merchant Center Account.
Update the titles in the Products section of your Shopify admin in the location that Google takes them from, either the main title and description or the SEO information, located at the bottom.
Generic image
Products with this error aren’t shown on Google.
Review these solutions and then update the data for the affected products:
For each item, you need to upload a main image that clearly shows the product being advertised.
Examples of generic images that aren't allowed include logo images or text that says "No image available".
Promotional overlay on image
Products with this error aren’t shown on Google.
Review these solutions and then update the data for the affected products:
Upload new images with no promotional text like logos or Calls to Action (CTAs), and no obstructing elements like watermarks. For more information, refer to Google's help article on fixing a promotional overlay on an image, and opting in for automatic image improvements.
Image too small
Products with this error aren’t shown on Google.
Review these solutions and then update the data for the affected products:
Upload new images that meet these size requirements:
Apparel & Accessories images need to be at least 250 x 250 pixels and no larger than 64 megapixels.
All other products need to be at least 100 x 100 pixels and no larger than 64 megapixels.
Images must have a file size smaller than 16 MB.
Don’t scale up images or submit thumbnails. We recommend the product take up 75%–90% of the full image.
Invalid value [Google product category]
Products with this error have limited performance.
Review these solutions and then update the data for the affected products:
Provide a valid Google product category (GPC) value.
Enter the most specific category possible. For example, entering only Tuxedos will cause an error, but Apparel & Accessories > Clothing > Suits > Tuxedos will be accepted.
Conflicting values [GTIN, brand]
Products with this error have limited performance.
Review these solutions and then update the data for the affected products:
Provide a GTIN value that's associated with the brand you submitted for the product.
Use the GS1 GEPIR tool to help verify GTINs for US brands.
