Cassini is eBay’s search engine, which operates much like Google does. Cassini uses three main factors in its algorithm:
Keywords – Cassini includes both the title and description sections when it analyzes your website.
Buyer behavior – People’s behavior when searching for a product and buying it is classified as click-throughs. Cassini will rank products higher if other people have clicked on them more often than others.
Seller performance – Cassini’s rankings also take into account sellers’ previous performance, including sales that have been successful, customer service and ratings.
