Online shopping is the activity or action of buying products or using services over the Internet. It means shopping online, landing on a seller’s website, selecting something, and arranging for its delivery. The buyer either pays for the goods or service online with a credit or debit card or select cash on delivery option. Online shopping has experienced a rapid growth during the past years due to its unique advantages for both consumers and retailers, which includes shopping at round the clock facilities, decreasing the frequency to store visits, saving travel costs, increasing market area, decreasing overhead expenses and offering a wide range of products.
More than 85% of the world’s online population has ordered goods over the internet during the recent years. Predicting and analyzing users' intentions for a particular product, or field, based on activities within a website is crucial for e-commerce websites and ad display networks, mostly for retargeting. By keeping records of the search patterns of the consumers, online merchants can have a clear understanding of their behaviors and intentions. In mobile e-commerce a good set of data is available and potential consumers browse for product details before making a purchase, thus reflecting consumer’s purchase intentions. Users always show different search patterns, i.e, time spent per item, search frequency and returning visits.
