When to use
Optional for each product
CLA custom labels are designed to help Comparison Shopping Services better organize CLA Shopping campaigns. CLA custom labels can be used for CLA campaigns, while existing custom labels are used for Shopping ads campaigns. This provides additional options to structure CLA campaigns without affecting the structure of Shopping ads campaigns.
The CLA custom label attributes are numbered 0–4:
- CLA custom label 0
[cla_custom_label_0] - CLA custom label 1
[cla_custom_label_1] - CLA custom label 2
[cla_custom_label_2] - CLA custom label 3
[cla_custom_label_3] - CLA custom label 4
[cla_custom_label_4]

Minimum requirements
These are the requirements you'll need to meet to show your product. If you don't follow these requirements, we'll disapprove your product and let you know in the Diagnostics page of your Merchant Center account you manage.
- Submit only 1 value for each CLA custom label
[cla_custom_label]attribute. - Create up to 1,000 unique labels for each CLA custom label attribute across your account (up to 5,000 labels total, 1,000 labels per attribute). If you submit products with a custom label after you exceed the limit, you won’t see reporting on products with those additional labels. You might also see other reporting errors. To fix the issue, reduce the number of unique labels, and then resubmit your product data.
- Use the CLA custom label attributes for CLA Shopping campaigns only. For Display with dynamic remarketing campaigns, use the ads labels
[ads_labels]and ads grouping[ads_grouping]attributes. Learn more about the Display ads attribute specification
Best practices
These best practices can help you go beyond the basic requirements to optimize your product data for performance.
- Create up to 5 CLA custom labels for each product: CLA custom label 0
[cla_custom_label_0]through CLA custom label 4[cla_custom_label_4] - Choose your own definition for each of the 5 CLA custom labels. You can add the values to each product in your Merchant Center account based on your definition.
- Use Feed Rules to assign CLA custom labels automatically based on values you already submitted in your product data. If you want a custom label to represent different price ranges, you could set a rule that automatically applies a certain value to CLA custom label 0
[cla_custom_label_0]based on the price range. For example, you might use the following labels: 0-5, 5-10, 10-20, 20+.
Examples
Set up your own definitions for CLA custom labels and include only one type of label per attribute. This definition isn’t something that you enter in Google Ads or Merchant Center, but it will help your own understanding of what values you should include.
| Attribute | CLA custom label 0 [cla_custom_label_0] |
| Your definition | Season |
| Example values | winter, spring, summer, fall |
| Attribute | CLA custom label 1 [cla_custom_label_1] |
| Your definition | Top Sellers |
| Example values | best seller, low seller |
| Attribute | CLA custom label 2 [cla_custom_label_2] |
| Your definition | Price ranges |
| Example values | 0-5, 5-10, 10-20, 20+ |
| Attribute | CLA custom label 3 [cla_custom_label_3] |
| Your definition | Margin |
| Example values | low margin, high margin |
| Attribute | CLA custom label 4 [cla_custom_label_4] |
| Your definition | Release year |
| Example values | 1998, 2000, 2010, 2016 |
For each product that you submit, you can include only one label (for example, “summer”) per attribute (for example, CLA custom label 0 [cla_custom_label_0]). However if you want to include multiple labels, add the other custom label attributes.
Remember that each of these attributes is optional. So include a CLA custom label only if it’s helpful to you.
