1. Track and analyze your web site traffic.
Most web hosts offer traffic analysis data to their clients, and it is arguably the most important tool at your disposal in measuring the effectiveness of your website. By taking the time to understand this data, you can begin to understand the motivations and interests of your audience. Are many of them leaving on one particular page? Perhaps you should make some changes to keep their interest. Are most of them looking at one particular part of your site? Perhaps you should make it a more featured area. Since this data updates on a regular basis, you are also able to gauge the effectiveness of any changes that you make. These are the most basic examples, as there are many more useful bits of information available- what search terms your visitors are using to find you, what sites are bringing you the most traffic, how long your visitors are staying, etc. Maintaining a successful website is an ongoing process, and visitor data is crucial to getting optimum results.
