PureClarity adds a number of attributes to Magento Products to help with PureClarity features.

When editing a Product in Magento admin, scroll down towards the bottom of the page and expand the PureClarity section and you’ll see the PureClarity attributes you can set against the product:

Search Tags are used in recommenders based on Search. You can add search tags to products, e.g. ‘Summer’, to boost the relevance of products based on visitors’ search terms. Enter a comma separated list of words or phrases that you’d like to be sent to PureClarity as Search Tags.

Set this to "Yes" to stop a product from being included in PureClarity recommenders. You may want to do this for small priced items.

Set if a product should be treated as a new arrival by PureClarity. This enhances recommenders and helps to target customers by showing hot new arrival products that may interest them.

Set if a product should be treated as an on-offer product. This enhances recommenders and helps to target customers by showing them products that are on promotion. PureClarity will do this automatically if products are on sale, however, you may want to override this if a product doesn’t currently have a special price, but you’d like it to be treated as a promoted product.
