In order to analyize and track your sites traffic and keywords you will need to install Google Analytics.
If you don’t have a Google Account nows the time to get one! Next you will need to visit http://www.google.com/analytics and enter a few peices of info about your site. Notice the account number you are assigned. It should begin with a “UA-“.
Lastly you will need to download a neat little Google Analytics plugin for WordPress. Simply install it to your content/plugins folder, then activate it inside WordPress Plugins Manager. While in WordPress, don;t forget to enter your UA # into the config box for the plugin.
This whole process will take you about 10 minutes and will give you detailed info about your traffic that is vital to the overall success of your site.
