Your website is like a salesperson available 24 hours a day. You will need to be able to gauge how profitable it is: these are statistics.
This makes it possible to find out:
- how many visitors your website receives (per day, month, ...)
- which pages are most visited
- the conversion rate, that is the percentage of visitors who have taken a particular action (for instance bought an article on line, registered for a newsletter, etc.). It all depends on the objectives you have set for your site.
You will be able to follow the success of your site step by step and correct any shortcomings to attract more visitors.
