According to many experts, a website search function is important for
all the following reasons:
sales. Effective site search means better usability, so customers can find
things more quickly. This can translate into higher sales, as customers
who find what they are looking for easily are more likely to make a purchase,
while site search also offers opportunities for merchandising.
conversion rates. More intuitive search and navigation means higher
site usage. A better user experience means that customers are more likely
to spend more time on the site, and can boost the number of registrations and
customer retention and loyalty. More loyalty as customers know they can find
products more easily.
