Using Custom Labels to Optimise your Google Shopping Feed

The problem with Google is that unless you have a way to divide your products based on their attributes or performance, you’ll have to blanket bid, meaning you’ll be bidding the same amount on each product. This results in inefficient campaign management.

Custom Labels may not directly impact performance on Google Shopping, but it does make the management of your campaigns a whole lot easier. It also allows you to have more granular control over bidding.


What are custom labels?

The Google Merchant Centre allows you to split your campaign’s products in to five fields, numbered 0 to 4, and these are called custom labels. You can then assign a definition to the labels and value to each product. For example:


Custom Label Your Definition Your Choice of Possible Values

Custom label 0


Winter, Spring, Summer, Autumn

Custom label 1


BestSeller, LowSeller

Custom label 2



Custom label 3


LowMargin, HighMargin

Custom label 4


50% off, 25% off


Assigning values to your products

For each product, you can assign a different value. For example, if the product falls under the custom label: “season”, then your products can be assigned the value “Winter”, “Spring”, “Summer”, “Autumn”, or can alternatively be left blank.

For example, not all products will have a profit margin.


Item id custom_label_0 custom_label_1 custom_label_2 custom_label_3
Item #1


Best Seller Clearance Low Margin 50% Off
Item #2


    High Margin  
Item #3  

Low Seller

    25% Off


No two product data feeds are alike and as campaigns run, they change based on the performance of certain groups of products.  

Therefore, there are two types of custom labelling: product attribute-based custom labels and performance-based custom labels.

Both allow you to adapt your product feed so that you can increase visibility and key performance indicators (KPIs) such as clicks or impressions.  

The key differentiator in performance, however, is whether you can apply these labels at scale, dynamically.


Product attribute-based labels

This is a way to divide your products based on physical characteristics such as:

  • Colour
  • Gender
  • Age group
  • Size
  • Brand

It also allows you to adjust bids, set rules or exclusions based on more popular characteristics.

For example, if you are a footwear retailer, you may find that your black shoes sell better than your navy shoes. You might, therefore, want to bid up on the black shoes.

This is how custom labels allow you to customise at a granular level.  


Performance-based labels

These labels relate to how products perform. When it comes to bidding, it’s important that all decisions are informed and based on how well a product is performing.

Custom Labels allow you to bid smarter. For example, you can reduce bidding on products under the label “low seller” and raise bids on those labelled “best seller”. You could also separate products based on whether they are “new in” or “old stock”. This will ensure the continued performance of your best-selling products and allow you to manage your stock efficiently.


Margin-based labels

Another way to segment your products is based on whether it has a high or low margin. This will help you drive profit as quickly as possible and prevent you from over-spending on CPC.


How Intelligent Reach enables retailers with the Label Manager

The Intelligent Reach Product Visibility Cloud allows retailers to simply create, assign and manage labels at scale in a matter of minutes.



Based on rules, the Label Manager allows you to separate your products based on attributes such as stock, price or margin so that you can better manage your data feed and avoid blanket bidding.
