Default: Sorted by the default product list.
Position: Looks at the position from the product details page. If you have allocated position numbers to your products, this will sort by those numbers.
Price: Sorted by the base cost of your products.
Product title: Sorted alphabetically by the product title.
Date added: Sorted by the date products were added to your eCommerce store.
Popularity: Looks at products that have been purchased and viewed across all customers to sort by the most popular products.
Recommended for me: Uses an algorithm that factors in the customer’s previous purchases, product views, top categories, popularity across all customers, and more to create a relevance score for each product. You can also use boost factors to decide which criteria to give the most weighting to. For example, you might want to give the highest boost value to recent orders, second highest boost value to recent views, third highest boost value to less recent orders, and fourth highest boost value to less recent views.
