First steps to setting up Google Analytics for your Web site
Make sure you have the Web site tracking code in the <head> tag on every Web page for your site.
Then setup Google Webmaster Tools for your Web site.
In the Admin tab on Google Analytics, navigate to Property -> Property Settings so you can connect Webmaster Tools for your site to your Google Analytics.
This enables organic keyword average positions to be tracked in your Google Analytics.
Once you have it connected and after 2 calendar days or more have past, navigate to Traffic Sources -> Sources -> Search -> Search Engine Optimization -> Queries in Google Analytics.
This displays any queries your site has organically appeared for in Google’s Search Engine Results Page (SERP, for short).
With these few steps you have setup your Google Analytics account to track the necessary data for an SEO to begin optimizing your site.
If your site serves a purpose, you can create Goals within Google Analytics to track conversions for the intended purpose of your site, so you can better optimize around the intended point of conversion you’d like people take.
A simple example of this is a Checkout page for a shopping cart, or a Success page for form submissions.
If you have these setup properly in Google Analytics, you’re already way ahead of the game to help improve your site over time for your customers/viewers.
