What is popularity sorting?
Sort by popularity is a filter tool that helps consumers choose to show targeted products with specific filter options related to the popularity of products like bestseller items, top ratings, and most reviewed items. Online shoppers love this function because they can investigate other previous buyers' experiences.
What is relevance sorting?
The default sort order is descending: The first results to be output are those at the top of the order. For example, the most relevant results are displayed at the top if they are sorted by relevance, the most recent results are displayed at the top if they are sorted by date, and so on.
