In my experience, a lot of people are more open about sharing traffic stats then you would think. You see this not just in interviews but if you peruse through the archived articles on a blog, there’s a good chance you’ll stumble upon a “blog in review” or “traffic report” post. With those stats, you can start to figure out how much traffic the site is getting today.
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.
