Every online business watches certain statistics about its website like a hawk. A website is designed to facilitate transactions, whether they involve purchasing products from the site itself or being redirected to another site. These transactions are a measurable variable that can be studied statistically. Each transaction represents a successful transition from visitor to customer. This transition is known as a “conversion.” Every conversion can be tallied and measured against the total number of visitors. The number of customers divided by the number of visitors yields a percentage that is called the conversion rate.
