Custom label (custom_label_0–4)
Definition: Custom labels (custom_label_0 to custom_label_4) are five optional feed attributes you use to group products in Google campaigns, for example Performance Max, Shopping and Demand Gen. Shoppers do not see them. Each attribute takes one value per product, from 1 to 100 characters.
They are your own tags: “bestseller”, “sale”, “season”. The platform does not interpret them, it just lets you filter by them.
Also called: custom_label, custom label attributes, custom_label_0

Why it matters for a shop
Labels let you split budget by your own grouping, for example promote new items and sale items separately. Without them you only have splits the platform knows: brand, category, price. They are the only way to carry what you know about your range into a campaign.
How Basketly handles it
- Feeds → Fixes and rules: set custom_label_0–4 from a template of attributes or through an “x => y” table (for example shop category → label).
- Products: the “no custom labels” check is a tip for Google, with no effect on refusal.
- The “Wyniki produktu” block in a flow lets you label products by impressions, clicks, orders or sales over the last 7–90 days.

What Custom label (custom_label_0–4) does not do
- A label does nothing by itself: its value must be used in a campaign.
- Shoppers do not see labels, so they do not replace a description or title.
Five attributes (0–4), each with one value per product and up to 1,000 unique values per account.
They are Google attributes. Meta has its own fields for grouping in product sets, so do not assume a label works the same way.
From shop data: category, price, date added. With a feed rule you can build a value from a template of attributes.
