The aim is to use your website traffic statistics to figure out how well or how poorly your site is interacting with its visitors, and then take the actions to improve your website's performance.
What you need to do:
1. Study your statistics, those that are important for your particular site.
2. Set your goals.
3. Formulate a strategy, based on your goals and current website's statistics.
4. Implement your strategy, making the necessary changes on your site.
5. Measure the effects of your implementation, comparing current statistics with previous ones, after a given period of at least 1 week.
6. Start again at step 2.
This process is ongoing and continuous.
