Prices must always be denoted in a simple numerical form using dot as the decimal separator. For example,
1.234,45 is invalid while 1234.45 is valid.Categories must always be delimited by a slash. For example,
/Home/Accessories is a valid category while Home > Accessories is not.The id of every category in the category hierarchy should be tagged. For example, if the product's category is
/Home/Accessories/Hats, the ids of Home, Accessories and Hats should be tagged.Currencies should always be represented in the ISO-4471 three-letter format. For example, use the code
USD instead of $ to represent the United States Dollar.The availability of a product is represented by
InStock or http://schema.org/InStock for products that are in stock and saleable. For products that are out of stock or you don't want to be recommended, you can use OutOfStock or http://schema.org/OutOfStockThe category of your item based on the Google product taxonomy. Use the schema provided by Google here (https://support.google.com/merchants/answer/6324436?hl=en)
The rating of a product must be represented as a number between 0.0 and 5.0. For example, a product cannot be rated 9.1. You must normalize your rating value to fit our specified range.
The three tag fields,
tags1, tags2 and tags3 are simply labels that can be used to annotate tags like discounted, limited collection or other use cases where you might want to filter your Nosto recommendations by certain product groupings.Custom fields accept a key:value pair where the
class of the attribute is the key. Common use cases are material, color or other similar unique identifiers.It is possible to tag also the currently viewed product sku. Typically this would be done on a product detail page when the user chooses a specific color or size and you would like to update recommendations to highlight other products with similar attributes. Most common approach would be to implement it by calling the Session API or the JS API from a click-listener to send the sku information and update the recommendations. If however the preference is to use tagging to specify the selected sku instead, that can be done through tagging by adding a span under product with the class name
selected_sku_id, for example: <span class="selected_sku_id">40822930473153</span>Nosto also supports two attributes that are not crawlable through tagging. This is due to the sensitive nature of the attributes. They are:
supplier_cost and inventory level. To send these two values to Nosto you will need to use the Products API.Many e-commerce stores utilize SKU:s or "child" products that are sorted under the same "parent" product. To extend the above example with SKU support refer to this article
In cases where a product might have multiple prices in differing currencies, you can also add support for multi-currency. Refer to this article
If you want to use Nosto’s margin filter, you need to send supplier cost via API since it's a sensitive data that you might not want to expose in the product tagging.
Once included on all pages, you can review if the site is transmitting data using the Nosto Debug Toolbar. If you can see product attributes being picked up under "Tagging" then the product details are correctly set up. You can further verify that products are being indexed to the catalog under the Nosto admin by navigating to Tools → Products: https://my.nosto.com/admin/$accountID/campaigns/products/list
