Having a website is great for any business, but figuring out whether it's attracting new customers is more of a challenge. Google Analytics is a powerful product that tracks all kinds of information about who visits you online and how they interact with your website, including:
The city or country visitors are browsing from
How long they stay on your website
Which pages they visit the most
Where they click through from
What parts of your website they click on
The most common routes visitors take through your website from page to page
You can also filter data based on a particular day, week, month, or whatever time period you wish to look at. This can help you gauge your website's performance over time and determine whether certain changes to your marketing strategy are having the desired effect.
