How to display my product price per measure unit?
This FAQ only applies to merchants who have a Google Merchant Center Pro version higher than or equal to 1.7.0.
For some product types (perfume, food, hardware, ...) the Google Shopping users may be interested in knowing the price per unit of volume, weight, surface, length, ... To see the product types primarily concerned click here.
Then, Google set two tags: "Unit pricing measure" and "Unit pricing base measure" that will be used with your product "price" tag. The "Unit pricing measure" tag is the total quantity or dimension of your product. The "Unit pricing base measure" matches the volume / surface / dimension etc... your users will want to considere as a reference to make, for example, product comparisons.
Example: you sell €18.55 a 30ml bottle of perfume. Your users may want to know the price for 100ml.
- The "Price" tag matches your product price: €18.55
- In the "Unit pricing measure" tag you must indicate the product volume: 30ml
- In the "Unit pricing base measure" tag you must indicate the reference volume: 100ml
Then Google will automatically calculate the unit price: (18.55*100)/30 = €64.83/100ml
"Unit pricing measure" and "Unit pricing base measure" tags are optional, but you may be required to provide this information based on local laws or regulations. For example, if your products target any of the EU member states or Switzerland, please consider the legal requirements on this matter defined in the national implementation acts of the EU directive 2010/30/EU and any other applicable local law.
Please read the Google's official guidelines about "Unit pricing measure" and "Unit pricing base measure" tags of the products advertised in Google Shopping attentively. Check well the units and values accepted by Google.
Important note: if you already use the "Energy efficiency class" tag for certain products (see our FAQ on it), do not use the "Unit pricing measure" tag for these products because Google will not display both. If both are present in the feed for a given product, Google will only display the information on the energy efficiency class.
The Pro version of our Google Merchant Center module allows you to include the "Unit pricing measure" and "Unit pricing base measure" tags in your product feed.
First of all you must create an "Unit pricing measure" feature in your PrestaShop back office:
and assign it the values matching with your products (for example "150ml", "30sqm", etc...). Do not put spaces between the number and the unit.
Then, you must assign the matching value of this feature to each relevant product directly in its product file:
Repeat the procedure by creating a "Unit pricing base measure" feature and assigning it reference values (for example "100ml", "100sqm", ...). Do not put spaces between the number and the unit.
Use the same units as for the "Unit pricing measure" tag. For example, if you used the ml for the "Unit pricing measure" feature values (for example "150ml", "30ml", ...) then also use the ml for the base measure (for example use "1000ml" and not "1l").
Go back again to the previous product files and assign them the correct reference value:
Once done, go to the "Advanced feed options" tab of the module "Product feed management" section and select "YES" for the "Do you want to include unit pricing measure tags?". A new option appears matching with the "Unit pricing base measure" tag. Also check "YES":
Save and for the option to insert "Unit pricing measure" tags, click "Configure the tag for each category".
You get a pop-up that lists all your categories(*). Assign the "Unit pricing measure" feature to each category including products for which you want to display the unit price value:
(*)Warning : please note that the categories we are talking about are the DEFAULT categories.
Then, in the blue box select the "Unit pricing base measure" tag type (or click "Update" and then click "configure the tag for each category" for the "Unit pricing base measure" tag option):
Assign the "Unit pricing base measure" feature type to the same categories as for the "Unit pricing measure" tag. Click "Update" and save the "Advanced tags" tab:
Once your product feed is sent, Google will calculate the unit price and display it in your Google Shopping ads.
