To get set up for Google Analytics, visit Google Analytics. You may need to set up an account and a profile for your Omeka site.
Log onto Google Analytics;
Click "Edit" for the profile you wish to use;
Click "Check Status" (it will be a small link near the top of the page);
Copy all of the text in the box labelled "Paste this code on your site"; and
Paste it into the box on the plugin configuration page.
That's it. You should start seeing results in Google Analytics in 24-48 hours.
