How much does it cost to bring in a visitor? Some web traffic is free, but many online stores rely on paid traffic — such as PPC or affiliates — to support and grow their business. Cost of Acquiring Customers (CAC) and Cost Per Acquisition (CPA) are arguably the two most important ecommerce metrics. When balanced with AOV (average order value) and CLV (customer lifetime value), a business can assess and adjust its ad spend as necessary.
Web traffic is the amount of data sent and received by visitors to a website. This necessarily does not include the traffic generated by bots. Since the mid-1990s, web traffic has been the largest portion of Internet traffic. This is determined by the number of visitors and the number of pages they visit. Sites monitor the incoming and outgoing traffic to see which parts or pages of their site are popular and if there are any apparent trends, such as one specific page being viewed mostly by people in a particular country. There are many ways to monitor this traffic and the gathered data is used to help structure sites, highlight security problems or indicate a potential lack of bandwidth.
