Once you have created and promoted your website, it is time to check on your site traffic. The basic statistics are: the number of visitors per day, where are they from, how they found your site and which pages they visited. Be wary of anyone quoting hits. To display a web page with 5 images takes a minimum of 6 hits. The real measurements are visitors and pages displayed. A visitor is a person or process accessing a page of your site.
Part of the code will be the Google Analytics’ UID. The structure will be UA-123456-1.
In the Website Profiles listing, this UID will be displayed beside the site address. The 123456 will be your account number. The first site will have -1 with each additional site -2 and so on.
Once installed, activate then go to Settings/Google Analytics and put in the UID supplied by Google when you added the site. There are other options that can be set such as not logging in when an administrator is visiting the site. This keeps the stats more accurate by removing your visits from it. Update the settings.
To validate that the plugin is working, visit your website and do a “Right Click-View Source.” You should see some code close to the top with your UID. It will take Google at least a day before any statistics will appear.
Google has excellent documentation on how to use the service. Now you can visit Google Analytics for statistics on your sites. There are other Google Analytic plugins, but this is the one I am most familiar with. It has served me well.
