--- title: Algorithms for widgets slug: product-recommendations/docs/algorithms-for-widgets docTags: createdAt: 2026-07-30T20:41:31.037Z --- Algorithms determine which products a widget recommends. You can add up to 11 algorithms to a widget to support your recommendation strategy. Each algorithm entry includes: - **Description** – The predefined logic the algorithm uses to recommend products. - **Compatible page types** – The pages where you can use the algorithm. You can apply [quick filters](docId\:fEZs5N4mm0r7o_ToL839S) and [advanced filters](docId:-TfhXXLAeMfX0v3UQ5AI4) to any algorithm to further personalize its recommendations. You should always have a fallback algorithm that is guaranteed to return recommendations when the other algorithms with more specific filters do not return a recommendation. :::hint{type="warning"} **Important** You should always have a fallback algorithm that is guaranteed to return recommendations when the other algorithms with more specific filters do not return a recommendation. ::: ## Abandoned basket - **Description** – Products abandoned in the user's basket. - **Page types** – All ## Added to basket after viewing - **Description** – Products added to the basket after viewing the current product. - **Page types** – Product, Basket, Checkout, WishList, Order ### Added to basket after viewing + smart score - **Description** – Products with the highest score and likelihood to be added to the basket after viewing the current product. - **Page types** – Product, Basket, Checkout, WishList, Order ### Added to basket after viewing + smart filter - **Description** – Products added to the basket after viewing the current product with the most statistically significant filter applied. - **Page types** – Product, Basket, Checkout, WishList, Order ### Added to basket from same category after viewing current product + smart filter - **Description** – Products from the same category added to the basket after viewing the current product with the most statistically significant filter applied. - **Page types** – Product, Basket, Checkout, WishList, Order ### Added to basket after viewing by segment - **Description **– Products added to the basket after viewing the current product, broken down by customer segment.  - **Page types **– Product, Basket, Checkout, WishList, Order  ## Basketed together - **Description** – Products added to the basket alongside the product currently being viewed. - **Page types** – Product, Basket, Checkout, WishList, Order ### Basketed together + smart filter - **Description** – Products added to the basket alongside the product currently being viewed with the most statistically significant filter applied. - **Page types** – Product, Basket, Checkout, WishList, Order ## Bestsellers by brand - **Description** – Products that sold the most for the specified brand. - **Page types** – All ## Bestsellers by units sold - **Description** – Products with the most units sold. - **Page types** – All ### Bestsellers by units sold in last 2 days - **Description** – Products with the most units sold within the last 2 days. - **Page types** – All ### Bestsellers by units sold in last 24 hours - **Description** – Products with the most units sold within the last 24 hours. - **Page types** – All ### Bestsellers by units sold in last 7 days - **Description** – Products with the most units sold within the last 7 days. - **Page types** – All ### Bestsellers by units sold + smart filter - **Description** – Products with the most units sold with the most statistically significant filter applied. - **Page types** – All ### Products in any category with most units sold - **Description** – Products from any category that have the most units sold. - **Page types** – All ### Bestseller by customer segments - Description – Products with the most units sold, by customer segment. - Page types – All - Variants – Two segment-matching variants are available: - OR – Recommends products to shoppers who belong to any selected segment. - AND – Recommends products only to shoppers who belong to all selected segments. :::hint{type="info"} **Note** As of version 1.4, a new field in the tracking request lets you handle your customers in the tracking requests.
