What is the meaning of Comparison Shopping Engines?
Comparison shopping engines – also known as price comparison websites – are websites that consumers can use to browse the same product sold by multiple retailers. Google Shopping is one prominent example; part marketplace, part advertising platform, it allows ecommerce businesses to store product catalogues and create campaigns to present ads to customers searching on Google. By integrating with Google, ecommerce sites can update products, prices, and stock levels to the Google Shopping platform.
