Web traffic is like when a lot of people show up to an event. Just like if you have a party at your house, you would expect that different people will show up at different times and some will stay longer than others. Web traffic is like that but instead of people showing up, it is visitors or users coming to the website. It is the number of visitors who show up to the website and how long they stay. It can tell us how popular the website is, what kinds of people are coming to the website, and where they are coming from.
