The first thing to investigate after a major dip in traffic is your website itself. Is it actually working? Is there a problem with the domain? Mechanically, is everything functioning as it should? If all that checks out, make sure the critical inbound links are still intact. If the majority of your traffic comes from inbound campaigns, ensure your inbound marketing platform is working properly. - Jeffrey Kamikow, Cross Audience

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.[1] 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.
