How does it benefit me?
Global Popularity is a powerful recommendation tool in Personalization Rules, which helps you create a general list of the most popular products. It includes the most-viewed and most-purchased items in the past 90 days from the customers’ Product catalog.
Use cases

Recommending popular items based on a certain price point

How does it work?
In order to create personalized recommendations we need to combine the following information:
- Your contact's browser history
- An item-to-item similarity based on the co-occurrence of products in the historical user sessions.
Interpreting the main logic
Globally popular products are the most popular products in a brand's product catalog. The ranking is based on the most-purchased and most-viewed products in the last 90 days from the brands product catalog.
- All products are considered that have at least 1 view or purchase event in the past 180 days.
- It is counted how many contacts have viewed or purchased each product and create a score.
- Filtering rules are applied (e.g., keep items above a certain price or items that belong to a certain category)
- The number of products that are returned to each contact is limited to 20.
Known limitations
Currently we do not have support for the following:
- Missing Parent-child level matching: One of the elements of our calculation is item-to-item similarity. This means that we might show the same item multiple times in one recommendation, just in different sizes, or color.
- Localized Fields: Not available yet.
- Like other Personalization rules, Personal Logic can only be used in batch type email campaigns. It cannot serve Transactional use cases (for e.g. abandoned cart).
- You can only send product personalized email campaigns to those customers who received any email from you in the last 180 days.
- Product Availability needs to be selected and filtered manually.
