The main objective of web analytics is to gain knowledge about who is coming to your website in order to make more and more people come to your website. The owner of the website really wants so many people to come to their site in order to either purchase their products or services.
They may also want people to just visit their site. There are some free sites that get their money through advertisements. They are not selling anything on their sites. Their whole purpose is to use web analytics in order to get more people to not only come to their site but also to stay there. They want the people to stay on their site for as long as possible.
