Simply put,. Integrating your account with Analytics will provide you with more detailed information about traffic to your pages and how users interact with your site. Many websites already have analytics included- and can be easily accessed. If you are not sure, call the web-site tech support and they can walk you through what they have. If you want more, you can add the Google analytics. It can be very helpful in telling you how to improve your website, ,and what just does not work! You should not go forward with any kind of marketing unless you are able to track the results, otherwise it is likely money wasted! Hope this helps.
