One way to measure the success of a website is to know how much website traffic it receives. Traffic or visitors doesn’t just flock a website once it’s launched out of nowhere, so some effort need to be poured to get the traffic you want.
Increasing website traffic requires quite a bit hard work, and it is a continuous process. It might be slow at first, but once it reach its tipping point, things will work automatically as the job is carried out by the visitors, voluntarily. All you need to do at that time is to monitor and promote the process.
